El NH-U12A es el más novedoso de los disipadores, la 5ª generación de disipadores de CPU de la galardonada serie NH-U12 de Noctua, de 120 mm, silencioso y de primera calidad. Concebido para traspasar los límites del factor de forma de 120mm, combina dos ventiladores NF-A12x25 PWM de 120mm, uno de los modelos más característicos de Noctua, con un disipador de 7 heatpipes y aletas con superficie ampliada para una mayor disipación térmica. De esta forma, el NH-U12A puede competir con el rendimiento de muchos de los disipadores de 140mm pero manteniendo una caja de 120mm y compatibilidad PCIe. También incluye el increíble y totalmente fiable sistema de montaje profesional multi-socket SecuFirm2™, el componente térmico de eficacia probada NT-H1 de Noctua y 6 años de garantía de fabricación, por lo que el NH-U12A se convierte en una opción de lujo que combina un rendimiento de máxima calidad con una excelente compatibilidad y un funcionamiento sorprendentemente silencioso.

Serie galardonada NH-U12

Serie galardonada NH-U12

La serie NH-U12 se presentó por primera vez en 2005 y ha sido galardonada con más de 600 premios y recomendaciones de sitios web y revistas internacionales especializadas. El NH-U12A es la última incorporación a esta prestigiosa serie y se ha establecido como una referencia entre los disipadores silenciosos de 120mm de mejor calidad.
Rendimiento de 140mm en tan solo 120mm

Rendimiento de 140mm en tan solo 120mm

Gracias a la disposición de los 7 heatpipes, completamente actualizados y optimizados, un 37% más de superficie en las aletas (comparado con el NH-U12S) y una configuración de entrada y salida con doble ventilador que utiliza los novedosos ventiladores de última generación NF-A12x25, el NH-U12A amplía los límites de los disipadores de 120mm y puede igualar o incluso superar a la mayoría de los disipadores de 140mm.
100% compatibilidad RAM para LGA115x y AM4

100% compatibilidad RAM para LGA115x y AM4

Debido a su diseño asimétrico, el NH-U12A no sobresale por encima de las ranuras de la RAM de las placas basadas en Intel LGA115x y AMD AM4, lo que garantiza un fácil acceso y una compatibilidad del 100% con dispersores de calor más altos. En el LGA2066, el ventilador trasero sobresaldrá por encima de las ranuras de la RAM en el lado izquierdo del socket, por lo que los módulos RAM no deberían superar los 42mm de altura.*
Tamaño de tipo torre clásico de 120 mm para una excelente compatibilidad con cajas y PCIe

Tamaño de tipo torre clásico de 120 mm para una excelente compatibilidad con cajas y PCIe

Con 158 mm de alto, el NH-U12A es lo suficientemente pequeño como para encajar en la mayoría de cajas de torre actuales de tamaño mediano y grande. Este disipador de 125 mm de ancho (incluyendo ventilador y sus ganchos de ajuste) se mantiene alejado de la parte superior de la ranura PCIe en la mayoría de placas base estándares ATX o Micro-ATX, garantizando la mejor compatibilidad posible con configuraciones multi-GPU.
Doble ventilador NF-A12 de 120mm

Doble ventilador NF-A12 de 120mm

El NF-A12x25 es un ventilador de 120 mm optimizado y de nueva generación que integra las últimas novedades de Noctua en ingeniería aerodinámica para conseguir un nivel de refrigeración silenciosa sin precedentes. El uso de este ventilador exclusivo con una configuración de entrada y salida de doble ventilador es uno de los puntos claves del magnífico rendimiento y eficiencia acústica del NH-U12A.
Soporte PWM y adaptador para la reducción del ruido

Soporte PWM y adaptador para la reducción del ruido

Los ventiladores NF-A12 de 120mm incluidos en el NH-U12A son compatibles con PWM para un cómodo control automático de la velocidad a través de la placa base. Pleno rendimiento con carga, prácticamente en silencio cuando se encuentra en reposo. Además, para conseguir un funcionamiento más silencioso, al utilizar los adaptadores para disminución de ruido que se incluyen, la velocidad máxima del ventilador puede reducirse de 2000 a 1700 rpm.
Sistema de montaje profesional multi-socket SecuFirm2™

Sistema de montaje profesional multi-socket SecuFirm2™

El sistema de montaje SecuFirm2™ de Noctua se ha convertido en sinónimo de calidad, seguridad y fácil instalación. El sistema de montaje SecuFirm2™ que se incluye con el NH-U12A es fácil de instalar, proporciona una presión de contacto perfecta y resiste el paso del tiempo incluso con un uso intensivo. Es compatible con Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156) y LGA20xx (LGA2066, LGA2011-0, LGA2011-3) así como con AMD AM4, AM3(+), AM2(+), FM2(+) y FM1.
Compatibilidad con los antiguos y nuevos sockets

Compatibilidad con los antiguos y nuevos sockets

Gracias al ecosistema del SecuFirm™ de Noctua, el NH-U12A es compatible con los antiguos sockets LGA1366 y LGA775 si se utiliza el kit de montaje opcional NM-I3 proporcionado gratuitamente. Si es técnicamente posible, Noctua también suministrará kits de actualización para sockets que aparecerán en el mercado en el futuro, lo que convertirá al NH-U12A en una inversión segura a largo plazo.
Compuesto térmico NT-H1

Compuesto térmico NT-H1

El aclamado NT-H1 de Noctua es una solución térmica de nivel profesional que proporciona una resistencia térmica mínima, gran facilidad de uso y una destacada fiabilidad. Se ha establecido como una referencia entre los compuestos térmicos de gran calidad ya que es uno de los más elegidos entre los overclockers y aficionados de todo el mundo.
Interfaz de soldadura entre heatpipes y aletas

Interfaz de soldadura entre heatpipes y aletas

En muchos disipadores las aletas se unen con presión a los heatpipes. Debido a los diferentes coeficientes de expansión térmica del cobre y del aluminio, esta unión podría soltarse con el paso de los años, lo que provocaría una disminución del rendimiento. En cambio, las aletas del NH-U12A están soldadas a los heatpipes para garantizar una interfaz térmica de mayor calidad que no se deteriore incluso tras varios años de uso.
6 años de garantía de fabricación

6 años de garantía de fabricación

Los productos Noctua son conocidos por su magnífica calidad y su destacada durabilidad. Para continuar con esta tradición, el disipador NH-U12 está diseñado para durar y, al igual que todos los ventiladores Noctua, el NF-A12x25 ofrece un MTTF (tiempo medio de fallo, sin posibilidad de reparación) de más de 150.000 horas. El paquete completo incluye una garantía de fabricación de 6 años.
*En cajas con un hueco para el disipador de CPU de más de 158mm, el ventilador trasero puede moverse hacia arriba para dejar hueco a los módulos de memoria que tengan más de 42mm.

NH-U12A Opinión

Now, onto the performance; this is where the Noctua takes the crown for the quietest cooler, thanks largely to those NF-A12x25 fans, once again they’re almost unbelievable in how quietly they operate, we saw idle noise levels as low as 25.5dB(A) and an average of 26. Even with the CPU overclocked to 4.4GHz, with an idle CPU power draw of roughly 70w, the fans didn’t nudge up by more than a single dB. While making a quiet cooler can be seen as relatively easy, you could just turn down the fan speed or reduce its size; maintaining decent CPU temperatures at the same time is what requires real expertise. Our Core i7 3930K didn’t peak any further than 63°C with our 4.4GHz overclock applied and stayed well below 60°C at stock clocks. Considering the 135W TDP, at stock, of this CPU, that result cannot be dismissed; there are coolers that are slightly better, but they all produce more noise in doing so. Pricing is somewhat of an Achilles heel of the Noctua NH-U12A, at currently around £20 more than the be quiet! Dark Rock Pro 4, which we feel is this heatsink’s biggest rival. The be quiet! Is a little louder but just as capable at keeping our i7 cool. However, things like memory compatibility will likely suffer with the Dark Rock. If quietness is paramount, then an extra £20 shouldn’t be too big of a hurdle.
Resultado del análisis: "If you absolutely must have a quiet system, this cooler is 100% for you; we can’t think of anything we’d recommend instead." (Matthew Hodgson, Vortez.net)

NH-U12A Opinión

Med resultaten i hand levererar nya NH-U12A riktigt bra prestanda med bara en grad över storebror NH-D15 i samtliga lägen. Det innebär att temperaturen aldrig stiger över 60 grader i redaktionens testmiljö, vilken är helt klart godkänt. Kylaren fortsätter att imponera sett till ljudnivå under full belastning, där lägsta ljudnivån mäter in på 36,5 dBA för LNA-läget. Nästa steg är PWM-styrningen på 37,5 dBA och fortfarande under närmaste läge för storebror NH-D15 på 39 dBA. Med datorn i vila blir kylaren helt knäpptyst på 34 dBA – samma nivå som rummets bakgrundsbrus och vi kan inte göra annat än imponeras av ljudnivån.
Resultado del análisis: "Prestandan och ljudnivån för NH-U12A är inget annat än imponerande och kombinationen den erbjuder är i dagsläget svårslagen. Det som håller den tillbaka just nu är priset, men samtidigt får köparen otroligt mycket tillbaka i form av ren prestanda." (Kenneth Lindqvist, SweClockers.com)

NH-U12A Opinión

A reality of coolers is that despite AIO liquid coolers often presenting themselves very impressively, a good solid air cooler will usually have it beat in terms of all-round performance. In this regard, the Noctua NH-U12A represents, or in fact is, one of the best coolers currently on the market. Furthermore, possibly one of the best ever made. Yes, it doesn’t carry the best aesthetics, but if (like me) you care more about performance than having seizure inducing RGB effects, then this is without a doubt one of the best coolers on the market at the moment!
Resultado del análisis: "Put simply, the Noctua NH-U12A is one of the best air-coolers currently on the market! As can be seen in both our stock and overclocked performance figures, it easily handled everything that was thrown at it while keeping the CPU cool and itself surprisingly quiet!"

NH-U12A Opinión

Ook maakt Noctua wat ons betreft zijn basisclaim - 14 cm koelprestaties in 12 cm form factor - waar. Weliswaar is het soms nek-aan-nek met de U14S, soms ligt die een neuslengte voor, dan weer een haarbreed achter, in de basis levert de NH-U12A exact wat er wordt beloofd. Dat is knap, want de recente jaren hebben we duidelijk gemaakt dat er niet veel rek meer zit in het perfectioneren van luchtkoeling. Ook in de grafieken is te zien hoe dicht de deelnemers bij elkaar liggen.Zeker bij relatief kleine hoeveelheden warmteproductie (65W, zoals een doorsnee mid-range processor levert) zit er amper 3 graden verschil tussen de nummer 1 en de nummer 17. Noctua kiest dan ook voor zo'n beetje de enige overgebleven manier om zich te onderscheiden (naast met montagegemak, afwerking en garantie), en dat is door dezelfde prestatie met een kleiner formaat te leveren.
Resultado del análisis: "De Noctua NH-U12A is zonder meer een technisch hoogstandje: voor zijn afmetingen is het de best presterende koeler die we hebben getest. Het rijtje 12cm-koelers dat hem überhaupt kan evenaren is beperkt: de Scythe Mugen 5 PCGH en Ninja 5, de Be quiet! Dark Rock Pro 4 - en alle zijn beduidend breder, waardoor je sneller tegen beperkingen bij het monteren aanloopt." (David van Dantzig, Hardware.Info)

NH-U12A Opinión

Der NH-U12A positioniert sich im Testfeld als leistungsstärkster Luftkühler. Und das auch, obwohl wir das große Dual-Tower-Modell NH-D15S als Vergleichsmodell extra noch einmal nachgemessen haben. Die Kombination aus Single-Tower-Kühler und Dual-Lüftern kann die Kombination aus Dual-Tower-Kühler mit einzelnem Lüfter sowohl bei maximaler Drehzahl als auch bei 1.000 U/min knapp schlagen.
Resultado del análisis: "Wenn diese wuchtigen Dual-Tower-Modelle aus Platz- bzw. Kompatibilitätsgründen nicht in Frage kommen, schlägt aber die Stunde des NH-U12A. Wir zeichnen diesen gelungenen Premiumkühler deshalb auch mit unserem Excellent-Hardware-Award aus." (Philipp Moosdorf, Hardwareluxx.de)

NH-U12A Opinión

Poboljšali su kompatibilnost s modulima radne memorije, te su poboljšali rashladna svojstva redizajnom tijela i povećanjem broja toplovodnih cijevi. Novi ventilatori su donijeli efikasniji prijenos topline u okolinu, a pri tome nisu pretjerano bučni (uz LN adapter i gotovo nečujni). Kvaliteta materijala i izrade je vrhunska kao i do sada i rijetko tko od konkurencije se može pohvaliti ovom razinom kvalitete. Zadržali su isti onaj jednostavni način ugradnje kompatibilan s većinom socketa na tržištu, a bundle je potpun. Jedino što bi voljeli da je nova NT-H2 pasta umjesto H1. Performanse hladnjaka NH-U12A su vrlo dobre, gotovo pa u rangu s nekim vodenim hlađenjima, a u slučaju neoverclockiranih procesora i bliske onima D15. Kada krenemo s overclockingom razlika postaje malo veća, no ne i tolika da ne bi U12A uzeli u obzir i dali mu prednost pred D15. Ponajprije zbog manjih dimenzija i veće kompatibilnosti.
Resultado del análisis: "Noctua nastavlja unaprjeđivati svoje već ionako odlične proizvode i ova nova generacija 120-milimetarskog hladnjaka za procesore je skoro pa bez mane." (Krešimir Matanović, PCEkspert.com)

NH-U12A Opinión

Nous avons intégré les résultats obtenus avec deux solutions en Aircooling et en Watercooling. Vous trouverez le Dark Rock 4 de Be Quiet! et le Watercooling AIO Kraken M22 de NZXT. Nous avons des solutions de refroidissement aux performances très proches. Le NH-U12A se positionne cependant devant ses deux concurrents avec un processeur à plein régime. L’usage des câbles L.N.A a un impact assez faible. Nous perdons 1°C au repos et 2°C en burn. Cette baisse des performances de refroidissement s’accompagne d’une chute des nuisances sonores. Le NH-U12A devient moins bruyant à plein régime. Notre sonomètre passe de 43.9 à 39.7 dBA. Avec deux ventilateurs de 120 mm en action, il n’arrive pas à égaler le Dark Rock 4. En considérant les nuisances sonores, ce NH-U12A signe de belles prouesses à la hauteur du Dark Rock 4 surtout en mode N.L.A.
Resultado del análisis: "Ce NH-U12A propose des prestations de premier plan. Ses performances de refroidissement font face à de forts besoins tandis que les nuisances sonores de ses deux ventilateurs sont bien maitrisées. Le bilan est donc positif avec un ventirad haut de gamme et soigné." (Jérôme Gianoli, GinjFo.com)

NH-U12A Opinión

The NF-A12x25 offers the silent level operations according to my ears listening and I can leave both fans at 100% of the speed at all the times. I personally don’t feel a need for the LNA. The graphs are self-explanatory when it comes to the thermal performance. The 120mm size cooler is offering the 140mm size cooler’s performance with an utmost clearance which is unlike the 140mm size coolers. Keeping in view the totality of the above factors, the price of the NH-U12A seems just right. The cooler has been tested on the Intel LGA2011(3) and AMD AM4 sockets. The cooler has beaten the other 120mm size coolers and 140mm coolers except the NH-D15 but it was sitting closer to the NH-D15 which is too good to speak of from this 120mm size cooler. The Noctua’ claim of 140mm size performance in 120mm size cooler is not without some truth and our testing is showing it to be. Just to validate the results, the other coolers were tested again using the same settings and methodology. Noctua once again delivered a powerful punch has left me wondering if they have raised the bar not only for the competition but for themselves as well, what would be their next gen dual tower 140mm cooler like!
Resultado del análisis: "This cooler with its extreme compatibility, low acoustic levels and better thermal performance has won our Must Have Award and comes recommended by us." (Nauman Siddique, EnosTech.com)

NH-U12A Opinión

Noctua vient marquer les esprits avec cette nouvelle révision du NH-U12, 14 ans après la sortie de celui-ci. La finition monte en gamme, la compatibilité est totale et les performances élevées pour ce modèle tour de 120 mm plutôt compact (bien que culminant à 158 mm). Le montage reste un régal sur les modèles de chez Noctua, surtout si vous possédez un socket LGA-20xx. L'artillerie déployée permet au NH-U12A de délivrer des performances d'un très bon niveau pour un modèle 120 mm. Si vous cherchez les performances dans un espace "réduit", ce modèle est en bonne place pour vous séduire. Les nuisances sonores générées par le ventirad sont élevées à pleine vitesse comme le montre le relevé effectué. Cependant, elles restent parfaitement maitrisées. Même à fond et largement audible, le bruit n'est pas gênant pour autant. La présence d'un bundle complet, l'ajout de deux caloducs et la présence des tout derniers NF-A12x25 fait monter le modèle en gamme, tant sur les performances que sur le prix.
Resultado del análisis: "À l'issue de notre test, nous laissons repartir le NH-U12A de Noctua avec la plus haute distinction. Le modèle est soigné, haut de gamme, bien équipé, facile à installer, très performant" (Thierry Comtesse, Le Comptoir du Hardware)

NH-U12A Opinión

Mit Blick auf die Lautstärke sei gesagt: Im Betrieb ist der NH-U12A bei halbierter Drehzahl überhaupt nicht hörbar. Und selbst bei 75 Prozent der Maximaldrehzahl kann nur ein nicht unangenehm auffälliges Luftrauschen vernommen werden - ruhig ist es auch hier. Hörbar und für Nutzer mit sensiblen Ohren nicht ganz bequem wird es bei maximaler Lüfterdrehzahl. Festzuhalten ist aber, dass die beiden NF-A12x25-Fans ihre Arbeit effektiv erledigen: Der statische Druck ist hoch, es entsteht ordentlich Durchzug, selbst bei verringerter Drehzahl, was unsere folgenden Messwerte im Hinblick auf die Temperaturen bestätigen. Denn hier glänzt Noctua erneut mit extrem guten Werten. Es macht hierbei praktisch keinen klar messbaren Unterschied, ob die Lüfter mit 50 oder 75 Prozent der maximalen Drehzahl drehen. Es bleibt recht kühl und bei maximaler Drehzahl kühlt der NH-U12A den Prozessor auf Mitte 50 Grad Celsius. Ein sehr guter Wert, wobei die Silent-Qualität hervorgehoben werden sollte: Langsam drehende Lüfter kann der NH-U12A gut ab, denn weitere Messungen mit unhörbaren 30 Prozent der maximalen Lüfterdrehzahl waren genug, um den Prozessor weiterhin unter die 60-Grad-Celsius-Marke zu halten.
Resultado del análisis: "Noctua macht es wieder: Ein top verarbeiteter Kühler, in dem viel Effort des Herstellers steckt, dazu mindestens genauso gute Lüfter - das zusammen ist eigentlich genug. Doch mit dem bekannten und einfachen SecuFirm2-Montagesystem setzen die Österreicher das I-Tüpfelchen. Beim NH-U12A handelt es sich um einen Kühler der Spitzenklasse, der sich auch mit deutlich voluminöseren Kühlern messen kann." (Issam Ammour, PC-Max.de)

How can I check whether my case is wide/high enough for the cooler?

How big is the NH-U12A and how much clearance does it provide for RAM and motherboard heatsinks?

Please refer to the following drawing for the exact measurements and clearance for RAM and motherboard heatsinks:

U12S

Due to its asymmetric design, the NH-U12A does not overhang the RAM slots on Intel LGA115x and AMD AM4 based motherboards, which ensures easy access to the modules and 100% compatibility with tall heat-spreaders. On LGA2066, the rear fan will overhang the RAM slots on the left-hand side of the socket, so RAM modules should not exceed 42mm in height. In cases with more than 158mm CPU cooler clearance, the rear fan can be moved upwards to make room for memory modules taller than 42mm.

What Thermal Design Power (TDP) is this cooler recommended for and how much Watt (W) of heat can it dissipate?

Please refer to our CPU compatibility list for information on maximum recommended TDP and heat dissipation.

Can I install a Noctua cooler in my system from Acer, Dell, HP or Lenovo?

Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often use motherboards which differ slightly from the specifications issued by Intel and AMD. While those changes are usually subtle, they can lead to compatibility issues with coolers that were built to comply with these specifications.

Even in case the cooler is mechanically compatible and can be installed, other issues can occur, e.g. proprietary fan connectors, BIOS errors due to a low fan speed, shutdowns, etc. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues can often not be resolved.

Due to the large number of possible issues that cannot be resolved with different mounting parts alone, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 600 or 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value in the BIOS that would suit the low minimum speed of Noctua PWM fans. The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply). Please note that any modifications performed with 3rd party tools are done at your own risk and that Noctua can not be held responsible for any possible issues.

Why doesn't the supplied backplate fit my LGA2066 / LGA2011 motherboard?

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA20xx (LGA2066, LGA2011-3, LGA2011-0). Please refer to the installation manual or our installation video for how to install the heatsink on LGA20xx.

I have difficulties installing the cooler, can you help?

Please refer to the installation manual and our video installation guides for detailed instructions on how to install the cooler.

Should I take the cooler off before transporting my system?

As it is not possible to reliably calculate or control the forces that act upon a system during transport (e.g. in shipping), we generally recommend, for safety reasons, taking the fan off the heatsink in order to reduce the weight below 700g. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the fan installed.

Can I keep using the backplate / mounting system of my previous Noctua cooler for my new one?

Most Noctua SecuFirm™ mounting parts are cross-compatible, so if you’re replacing one Noctua cooler with another, it is usually possible to keep the original backplate and/or mounting system in place in order to re-use it for the new cooler. If you had your previous Noctua cooler installed on an Intel LGA115x (LGA1156, LGA1155, LGA1151, LGA1150), LGA2011 (LGA2011-0, LGA2011-3) or LGA1366 system and replace it with an NH-U14S, NH-U12S or NH-U9S, you only need to replace the original mounting bars with the NM-IMB3 ones supplied with the new cooler. For all other models, you can keep the entire mounting system in place on the aforementioned Intel sockets. On AMD AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+, you only need to replace the original mounting bars with the ones supplied with the new cooler.

How much torque should be applied when tightening the screws of a Noctua CPU cooler?

All screws should be tightened gently until they stop without using excessive force. Please do not exceed the following values for maximum tightening torque:

Which Noctua fan or CPU cooler should I buy? How to choose the right model?

Not sure which Noctua product to buy? Our detailed buying guides for fans and CPU coolers help you to choose the model that works best for you.

How can I determine if the motherboard’s UEFI BIOS is overclocking my processor by default and deactivate this automatic overclocking?

Most motherboard vendors allow their overclocking-enabled products (e.g. those with Intels X- or Z-series chipsets) to run the processor at increased clock speeds by default, without requiring any user action at all. Since TDP (Thermal Design Power) limits are usually also disabled by default, this leads to the CPU exceeding the rated TDP to a varying degree, depending on the used applications and their workloads. Due to the increased heat output of the CPU, you may see higher CPU temperatures than expected.

In order to find out if your motherboard is overclocking your processor by default, please enter the UEFI BIOS and select the “advanced” or “overclocking” menu. There you should be able to find options such as “MultiCore Enhancement” (options: enabled/disabled), “CPU Ratio Apply Mode” (options: all/per core) or similar. To disable the automatic overclocking, adjust the settings either to “disabled” or “per core” and make sure that the individual multipliers match the original specifications.

In doubt, please contact your motherboard vendor for detailed instructions on how to disable this feature.

Can I upgrade my existing Noctua cooler to socket TR4 or SP3?

Unfortunately, it is not possible to upgrade existing Noctua heatsinks to support the AMD TR4 and SP3 sockets for Ryzen Threadripper (X399) and Epyc CPUs. TR4/SP3 CPUs have much bigger heatspreaders (as compared to e.g. LGA2066 or AM4 processors) and the contact surfaces of standard Noctua heatsinks would cover only about half of these heatspreaders, which would result in insufficient cooling performance. On top of that, the heatpipes of bigger cooler models like the NH-D15 or NH-D15S would completely block the RAM slots on many TR4/SP3 motherboards. For this reason, Noctua has introduced the new NH-U14S TR4-SP3, NH-U12S TR4-SP3 and NH-U9 TR4-SP3 cooler models that feature bigger contact surfaces and have been tailored to fit TR4 and SP3 systems. Please choose these models for AMD Ryzen Threadripper and Epyc systems.

Is it possible to use the cooler with vertical graphic cards?

Depending on the chassis, card and motherboard being used, installing PCIe cards in a vertical position using riser cards may cause compatibility issues with CPU coolers. Whether there will be a problem or not depends on the exact position of the card (which is determined by the PC case and/or optional vertical GPU holder bracket), the width of the card as well as the position of the CPU socket on the motherboard. In order to verify that there is sufficient space for the cooler, please measure the distance between the centre of the CPU socket and the top of the PCI card in order to make sure that the cooler fits.

My Intel CPU is running too hot although my heatsink supports the specified TDP, what's the problem?

Current processors from Intel, especially the unlocked models with the suffixes C, K, X or XE (e.g. Core i7-8700K, Core i9-7900X oder Core i9-9900K) can dissipate noticeably more heat than indicated by the TDP specification.

While many motherboard models stick to the recommended power levels and clock speeds settings from Intel, there are models where the UEFI BIOS is configured in such a way that:

  1. the TDP limits are extended or disabled.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.

Depending on the load scenario and CPU configuration settings, the actual power draw can be 1.5-3 times as high the stated TDP value. This can lead to temperature issues, especially when using smaller coolers, compact cases or cases with poor airflow, when some applications create very high loads, e.g. Prime95 with AVX2 support, 3D-rendering or simulation software.

The actual power draw of the processor can be monitored with software provided by the motherboard vendor or with 3rd party tools like HWInfo or HWMonitor.

If you encounter temperature issues (>90°C) and notice a higher than specified power draw, please ensure that no automatic overclocking is applied. You might also want to limit the TDP to either the specified value by Intel or a value that is 5-10W below the value previously read out from the CPU. This can be done in BIOS by setting the “Long Term Duration Power” manually instead of “Auto”.

Furthermore, it may also help to lower the CPU clock speed for applications that heavily use the AVX instruction set, which can lead to higher loads and power draw. This option is usually referred to as “AVX offset” and makes it possible to lower the multiplier specifically for AVX based applications without reducing performance when using other instruction sets. Depending on the quality of the CPU and the programs being used, a reduction of 2-3 steps usually gives very good results.

The option to set an AVX-offset value is usually available for the following CPU generations:

  • LGA1151:7th, 8th and 9th generation (Kaby Lake, Coffee Lake)
  • LGA2011-3: 6th generation (Broadwell-E)
  • LGA2066: 7th and 8th generation (Skylake-X)

Please contact your motherboard vendor for details if you have trouble finding the appropriate settings in the BIOS.

All our TDP recommendations are based on thorough testing with the default values specified by Intel using popular applications such as Asus Realbench and prime95. Please note, however, that prime95 creates a particularly high load that goes beyond most typical application scenarios and this leads to elevated temperatures. We thus recommend using other programs such as Realbench for checking the stability and temperatures of the CPU in realistic scenarios.

Please also note that CPUs that use thermal paste instead of soldering between the DIE and the heatspreader generally run hotter. Due to the thermal bottleneck created by the thermal paste, temperatures can be high even at the specified TDP.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

    Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

    Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.


    If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

Which sockets are supported or can be supported using upgrade kits?

Please refer to our socket compatibility chart.

I can't open the socket due to the mounting bars!

Please first loosen one of the two thumbscrews that hold the mounting bars in place. Then untighten the second screw so that you can swivel the mounting bar and open the socket. Depending on the position of the mounting bars, you may need to swivel both.

Can the cooler be installed turned by 90° on AMD sockets?

No. The new SecuFirm2™ mounting system for AM2, AM2+ and AM3 uses the same standardised hole spacing as the Intel system and thus allows for a much easier installation, but the cooler cannot be installed turned by 90°.

Does the package include a backplate for AMD AM2(+)/AM3(+)/FM1/FM2(+)?

No. As most AMD mainboards come with a stock backplate preinstalled, the cooler doesn’t include an AMD backplate. If your mainboard doesn’t have a backplate, please contact our support team at support@noctua.at.

amd backplate

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independently from the second fan’s rpm signal.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

How can I check whether my AMD mainboard has a standard AMD backplate that’s compatible with the SecuFirm2™ mounting system and how should I proceed with the installation?

The SecuFirm2™ mounting system requires a standard AMD backplate (either plastic or metal) with screw threads as shown on the pictures below. These backplates are pre-installed on the rear side of most AMD mainboards (see first picture below) and fixed to the retention module with four screws (see second picture below). If your retention module is fixed with plastic bolts instead of metal screws, please contact support@noctua.at in order to obtain an appropriate backplate.

In order to proceed with the installation of your Noctua cooler, please remove the four screws and the retention module but keep the backplate in place so that you can see the screw threads from the top side of the motherboard (see third picture below). You can then proceed with the installation of the SecuFirm2™ mounting kit as described in the manual (see fourth picture below).

How to remove the base protection cover?

Noctua CPU coolers are shipped with a plastic protection cover at the bottom side of the cooler, which protects the contact surface against scratches and other damage.

The base of Noctua CPU coolers is made from hard-wearing nickel plated copper, so there's nothing to worry about if you buy a Noctua cooler from second hand or if your cooler didn't come with a protection cover. Please proceed with the installation as explained in the manual.

You can simply remove the cover as shown below:

I get a CPU fan error using my Noctua PWM fan, is it faulty?

Noctua PWM fans feature a minimum speed of 300rpm to allow for ultra quiet operation when your CPU is at idle state and doesn’t require higher cooling performance. Some mainboards display error messages such as “CPU fan error” during the booting process when the fan speed is below a certain level. If you get such error messages using your Noctua PWM fan and if such options are available in your BIOS, please either adjust the minimum fan speed monitoring limit to 200rpm or increase the minimum PWM duty cycle. If your BIOS doesn’t offer these options, please disable CPU fan errors. For detailed information on BIOS fan settings, please consult your mainoard’s manual or contact your mainboard manufacturer.

Does the mounting-system support LGA2011 based Xeon CPUs?

There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing. The Square ILM socket is mechanically identical to the LGA2011 socket for Core i7, so the mounting-system is fully compatible, but it is not compatible with Xeon mainboards that use the Narrow ILM:

How should I clean my Noctua cooler?

Dust: Fans and heatsinks inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fan and heatsink regularly. For cleaning, please first remove the fan from the heatsink and clean it using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please do not use a vacuum cleaner as this may apply excessive force to the fan and do not put the fan under running water as water residues inside the motor may lead to short circuits. Please also note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty. Before reinstalling the fan, clean the heatsink itself with a duster or vacuum cleaner. Do not use water to clean the cooler. Finally put the fan back on and connect it to your motherboard fan header or fan controller.
Thermal paste residues: Whenever you take off the heatsink from the CPU, we recommend to clean the CPU as well as the base of the cooler before re-applying thermal paste and re-installing the cooler. You can either just wipe the base and the CPU clean with a dry, lint-free tissue or, for more thorough cleaning, use a lint-free tissue moistened with either a mild solution of washing-up liquid or isopropyl alcohol. Do not put the cooler or CPU under running water. Note that both the base of the heatsink and the CPU should be dry, free from residues of thermal compound and free from grease before re-applying thermal paste and re-installing the cooler.

Why is the cooler’s contact surface slightly convex?

As the Integrated Heat Spreaders (IHS) of today’s CPUs are slightly concave, the cooler’s contact surface has been deliberately designed to be slightly convex in order to ensure optimal contact. This way, more contact pressure will be applied at the centre of the IHS directly above the DIE, which results in better heat transfer and improved overall performance.

Is the cooler compatible with LGA775 and LGA1366?

The cooler does not support LGA775 and LGA1366 out of the box, but can be made compatible using the NM-I3 mounting kit. Noctua provides the NM-I3 kit free of charge if a proof of purchase (scan, photo or electronic copy of the invoice) of the cooler and an LGA775 or LGA1366 motherboard or CPU are presented. In order to install the cooler using the NM-I3 kit, please first unscrew the center screw of the original one-piece fastening bracket (you can reach through the fin stack using the long screw driver supplied with the cooler) and remove it. Then install the two fastening brackets of the NM-I3 kit as described in the NM-I3 installation manual.

I’ve used all the NT-H1 thermal compound that came with the cooler, can you send me more?

Please kindly note that the NT-H1 thermal compound supplied with our coolers is a consumable item so our manufacturer’s warranty does not include providing additional thermal compound. You can purchase NT-H1 from our resellers.

How can I check whether my case is wide/high enough for the cooler?

Most case manufacturers provide specifications for maximum CPU cooler height/clearance. Please refer to these specifications in order to verify that the cooler will fit the case. If no specifications are available, please contact the case manufactuer or measure the distance from the motherboard tray to the side panel (tower cases) or top panel (desktop cases). If this distance is bigger than the height of the cooler + 15mm (mainboard spacers + mainboard + CPU), the height/width of your case should be sufficient.
