Conçu pour offrir une comptabilité accrue tant au niveau des modules de mémoire que des slots PCIe, le NH-D15S est une version asymétrique simple ventilation issue du célèbre modèle phare NH-D15 de Noctua. Grâce à son design asymétrique, le NH-D15S libère de l’espace pour les slots PCIe sur la plupart des cartes mères µATX et ATX. De plus l’utilisation d’un seul ventilateur et la réduction des ailettes inférieures du radiateur assurent une compatibilité parfaite avec les modules mémoire pouvant atteindre 65mm. Pour les utilisateurs ayant une certaine marge de manœuvre au niveau de l’espace disponible, il est par ailleurs possible d’améliorer encore les performances en installant, sur la face avant du radiateur, un deuxième ventilateur 120mm ou bien un modèle rond 140mm. Livré avec le système de fixation professionnel ultra sécurisé et multi-socket SecuFirm2™, la célèbre pâte thermique Noctua NT-H1 et assorti d’une garantie fabricant totale de 6 ans, le NH-D15S constitue une solution premium complète combinant l’efficacité d’un radiateur à double empilage d’ailettes avec un niveau incroyable de modularité et de compatibilité.

Un NH-D15  révisé pour un compatibilité extrême

Un NH-D15 révisé pour un compatibilité extrême

Comparée au célèbre NH-D15, la version S jouit d'un design déporté asymétrique et se voit dotée d'un seul ventilateur NF-A15 (au lieu de deux). De telles mesures permettent à ce nouveau modèle d'atteindre un niveau de refroidissement excellent tout en garantissant une meilleure compatibilité RAM et PCIe.
Compatibilité RAM excellente

Compatibilité RAM excellente

Grâce à des ailettes inférieures réduites, le radiateur du NH-D15S dégage un espace de 65mm pour les dissipateurs de modules mémoire hauts ce qui le rend compatible avec la plupart des meilleurs modules du marché. Grâce à un retrait des ailettes inférieures des deux côtés du radiateur, la compatibilité est excellente sur les LGA115x et AMD mais aussi sur les LGA2011, ces derniers possédant des emplacements mémoire des deux côtés du socket.
Un design asymétrique pour une compatibilité PCIe accrue

Un design asymétrique pour une compatibilité PCIe accrue

Compte tenu du fait que la plupart des cartes mères sont pourvues d'emplacements PCIe x16 aux proches abords du socket, les empilages d'ailettes volumineux restent un obstacle. Grâce à son asymétrie, l'empilage d'ailettes du NH-D15S est décalé en direction de la partie supérieure de la carte mère lors d'une installation traditionnelle. Sur la plupart des cartes mères µATX et ATX*, ceci permet de libérer de l'espace pour les emplacements PCIe x16 situés en extrémité.
Ventilateur NF-A15 140mm

Ventilateur NF-A15 140mm

Répondant aux critères du standard AAO de Noctua, le NF-A15 possède un design bénéficiant des dernières avancées en matière d'aérodynamisme telles que les Flow Acceleration Channels. Il s'est ainsi rapidement forgé une solide réputation pour devenir aujourd'hui un des meilleurs ventilateurs 140mm du marché.

Grâce à l'utilisation des agrafes pour ventilateurs fournies, le NH-D15S peut être équipé, au choix, d'un second ventilateur 140mm à cadre rond avec orifices de fixation à la norme 120mm (par exemple le NF-A15) pour une performance maximale ou bien d'un ventilateur 120mm traditionnel (tel que le NF-F12) afin d'assurer un gain de performance tout en garantissant une compatibilité avec les modules de mémoire atteignant une hauteur de 45mm.
Compatibilité PWM et Adaptateur Faible bruit (L.N.A.)

Compatibilité PWM et Adaptateur Faible bruit (L.N.A.)

Le ventilateur haut de gamme NF-A15 fourni avec le NH-D15S est compatible PWM pour un pilotage automatique et confortable de la vitesse via la carte mère. De plus, et afin de réduire encore le niveau sonore, la vitesse de ventilation peut être plafonnée (de 1500 à 1200 tr/min.) grâce à l'utilisation de l'adaptateur faible bruit (L.N.A.).
Un refroidissement efficace des composants de la carte mère

Un refroidissement efficace des composants de la carte mère

Dépassant la simple zone de l'empilage d'ailettes sur sa zone inférieure, le positionnement du NF-A15 permet au NH-D15S de refroidir efficacement le CPU mais aussi de délivrer un flux d'air important en direction des composants et autres dissipateurs environnants présents sur la carte mère qui se trouve ainsi refroidis avec grande efficacité.

NH-D15S test

Esistono in commercio moltissimi dissipatori ad aria che fanno più o meno il loro dovere. Il Noctua NH-D15S però, è secondo me il miglior dissipatore ad aria per processori Intel e AMD che esistano sul mercato. Difficile trovare un dissipatore in commercio per appassionati o per utenti che vogliono il “Top” che riesca ad offrire qualità, prestazioni, silenziosità e facilità di montaggio. Tutte queste ottime caratteristiche e tutte le tecnologie utilizzate in un unico dissipatore, ne giustificano pienamente il prezzo. Questo dissipatore Noctua NH-D15S è abbastanza simile all’NH-D15, ma non è la stessa cosa. Ha una ventola in meno, è progettato meglio nel design per essere compatibile con tutti i moduli RAM ed è ancor più silenzioso.
Verdict du test: "Se volete il “Top” dei dispositivi di raffreddamento ad aria, il Noctua NH-D15S è proprio il dissipatore che stavate cercando." (TechUniverse.it)

Noctua NH-D15S nėra silpnesnė ar galingesnė NH-D15-ojo versija. Ji yra tiesiog kitokia. Viskas tarsi „sufotošopionta“ – perstumta kitaip, tačiau nenutrinta ar nepripiešta. Labai neįprasta matyti asimetriškos formos procesoriaus aušintuvą – tokie sprendimai yra ypač reti, ypač Tower tipo aušintuvuose. Keista matyti kaip pastačius aušintuvą ant lygaus pagrindo jis ima virsti ant šono.

NH-D15S test

Oba modely rakúskeho výrobcu sú porovnateľné a veľmi vyrovnané chladiče do PC, ponúkajú takmer rovnaké parametre (teda až na to, že NH-D15S ponúka v základe jeden NF-A15 a v prípade potreby si druhý kus musí používateľ kúpiť samostatne). Oba modely sú za danú cenu vhodné na kúpu do každého počítača, potešia však najmä hráčov a náročných používateľov. Mnohí však v dnešnej dobe siahnu aj po novom fenoméne – vodnom chladení (či už ide o skladacie, alebo oveľa prístupnejšie AiO – teda all-in-one). Ten v skrinke síce lepšie vyzerá, ale mnohí majú radi klasiku. A ktorý z dvojice testovaných modelov odporúčať? Podľa nás sú výborné oba, avšak vzhľadom ku kompaktnejším rozmerom a o niečo nižšími nameranými hodnotám, sa prikláňame k modelu Noctua NH-D15S. Ponúkne totiž pomerne tichý chod, podáva výborné chladiace výkony a má širokú podporu socketov. Páči sa nám dizajn dvoch veží, medzi ktoré sa umiestni ventilátor „dovnútra“ chladiča a okolo neho tak zostane dostatočný priestor pre pohodlné usadenie RAM a ostatných komponentov v blízkosti chladiča.
Verdict du test: "Podľa nás ide jednoznačne o výbornú voľbu medzi vzdušnými chladičmi a oba modely rozhodne odporúčame!" (Martin Klokner, DigitalPortal.sk)

Noctua wist weer een goed product op de planken te leggen. Ik verwachtte ook een zeer goede prestatie van deze koeler. Ik heb al diverse ventilatoren in mijn computer geplaatst voor betere airflow en koeling. Waar ik heel erg blij mee ben is dat ze geruisloos de strijd aan gaan met de warmte van de computer. Perfecte koeling, luxe uitstraling en een lange garantie van 6 jaar. Wat wil je als gamer nog meer? Je wordt niet geïrriteerd door suizende ventilatoren of irritante tikjes. Conlusie: de producten van Noctua kan ik zeer zeker aanbevelen. Wil je jouw game level naar een nog hoger niveau brengen? Ben je opzoek naar een luxe product voor een fantastische prijs? Dan zal ik er vandaag nog een aanschaffen! Leuk voor onder de kerstboom. ;-)
Verdict du test: "Deze processorkoeler van Noctua stel je niet teleur! Het is een geweldig product, ik had zeer hoge verwachtingen en deze werden boven verwachting waargemaakt. Alles draait als een zonnetje en ik hoor de koeler haast niet tijdens mijn game sessies. Na een lange tijd op 100% te hebben gedraaid, maakt hij geen ratelende of irritante geluiden. ‘High class product!’" (Rob Lammerts, Tweakers.net)

NH-D15S test

Ce NH-D15S est une véritable réussite. Simple et rapide à monter. Compatible avec des kits de RAM avec radiateur, il faudra tout de même veiller à ce que votre tour soit assez large pour pouvoir l'intégrer. Quant à son efficacité, c'est simple, il est excellent, un des meilleurs actuellement. Alors oui il ne révolutionne pas les solutions de type aircooling, mais il a le mérite de bien remplir son rôle. Cela dit au prix de 80 euros c'est logique. Mais avec ce NH-D15S, vous êtes tranquille et votre CPU au frais. Paradoxalement, je ne le conseillerais pas à tout le monde d'une part parce qu'il demande un boitier assez volumineux mine de rien et d'autre part parce qu'il n'est pas à la portée de toutes les bourses. Ce ventirad s'adresse avant tout aux personnes ayant un bon budget et une tour imposante qui l'acceptera. Pour ceux qui souhaitent l'acquérir, une chose est sûre, vous ne regretterez pas de casser votre tirelire. C'est un produit fini et complet qui vous suivra un bon moment vu qu'une prise en charge des futurs sockets est prévue.

NH-D15S test

Noctua NH-D15S крайне схожа с предшественницей в лице NH-D15. Не держа в руках одновременно оба охладителя даже отличить сложно. По сути, NH-D15S можно назвать работой над ошибками. В свое время кулер NH-D15 был великолепен и изумителен, но мог вызвать немало головной боли из-за перекрытия слотов расширения, а на некоторых платах и вовсе перекрывал единственный слот PCI-Express. Не изменяя существенно конструкцию радиатора, которая свою эффективность доказала не раз и не два, инженерам Noctua удалось добиться гораздо лучшей совместимости, и в первую очередь на платах форм-фактора mini-ITX и micro-ATX, набирающих все большую и большую популярность.

Pokud se někdo lekl toho, že D15S je menší a má jen jeden ventilátor v základu než předchozí D15, tak už vidí, že není čeho se bát. Ano, v extrému může mít i malinko nižší výkon, ale rozdíl je naprosto zanedbatelný v praxi. D15S má dokonce osazena dvojicí ventilátorů (což je stále možné), o malinko lepší výkon než D15. Nicméně cílem bylo hlavně zlepšit kompatibilitu osazení chladiče a tady musíme říci, že se mise opravdu velmi zdařila.

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.

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.

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:

Base Protection Cover

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:

Xeon Compatibility

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.

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

Please refer to our socket compatibility chart.

Is the cooler compatible with the LGA2011-3 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA2011-0 and 2011-3, the cooler supports both types of LGA2011-3.

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.

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.

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

Please refer to our TDP guide for information on maximum recommended TDP and heat dissipation.

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 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 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, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

How big is the NH-D15S and how much clearance does it provide for RAM and mainboard heatsinks?

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

D15S

Is the cooler compatible with the LGA1151 socket?

Yes. Due to the heatsink mounting mechanism being identical on LGA1150, LGA1151, LGA1155 and LGA1156, the cooler also supports LGA1151.

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

The supplied backplate is for LGA115x only and there is no backplate required for installation on LGA2011. Please refer to the installation manual for how to install the heatsink on LGA2011.

My case supports CPU coolers of up to XXXmm height, which model should I choose?

Please refer to our TDP guide in order to select the cooler that offers the best cooling performance at a given height.

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 cooler off. Noctua cannot be held responsible for any damage that may arise due to excessive stress during transport if you keep the heatsink installed.

Does the NF-A15 PWM that comes with Noctua coolers run at a different speed (1500rpm) than the retail model (1200rpm)?

Yes, the NF-A15 PWM bundled with our heatsinks is specified to run at 1500rpm (see cooler specifications for details) and the retail model is specified to run at 1200rpm (see fan specifications for details). The 1200rpm retail model is ideal for setting up push/pull configurations in combination with the coolers’ 1500rpm stock fan because the combination of the 1500 and 1200rpm models provides a better balance of performance and noise than the combination of two 1500rpm versions. On dual-tower coolers such as the NH-D15S, we recommend to run the 1500rpm version in the center and the 1200rpm version on the front. On single-tower coolers such as the NH-U14S, we recommend to run the 1500rpm version on the front and the 1200rpm version on the back of the cooler. The NA-YC1 y-cable supplied with the retail fan can be used in order to control both fans via one PWM fan header. In this case, both fans will scale individually according to the PWM duty cycle supplied by the motherboard, e.g. they will run at ~1500/1200 respectively at 100% duty cycle, ~750/600rpm at 50% duty cycle, etc. Both at 100% and lower speeds, the speed difference between the fans reduces resonance phenomena and thus helps to achieve the best balance of performance and noise.

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:
Screw typeMax. torque
NM-SSC1 screws for fixing the fastening brackets to the base of the heatsink0.5 Nm
NM-ITS1 thumb screws for fixing Intel mounting bars0.5 Nm
NM-ALS1 screws for fixing AMD mounting bars0.6 Nm
Spring-loaded screws for fixing the heatsink to the mounting bars0.6 Nm

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.

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

Intel's unlocked CPUs (K, X and C suffix) can dissipate more heat than indicated by the TDP specification if
  1. the TDP limits are extended or disabled in the motherboards' BIOS.
  2. the motherboard applies automatic overclocking by default, e.g. by raising the supply voltage of the CPU and using higher Turbo-Mode multipliers.
  3. some software creates untypical loads, e.g. Prime95 with AVX2 support and a) and/or b) apply.

This can lead to temperature issues, especially when using smaller coolers or compact cases.

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 and limit the TDP to the specified value by choosing appropriate BIOS settings.

For Kaby Lake CPUs, 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.

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 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.

Which Noctua CPU coolers are compatible with Intel LGA2066?

Due to the heatsink mounting mechanism being identical on LGA2011 and LGA2066, Noctua’s SecuFirm2™ mounting systems for LGA2011 also support Intel’s upcoming ‘Basin Falls’ X299 HEDT (High End Desktop) platform for ‘Skylake-X’ and ‘Kaby Lake-X’ processors. Most current Noctua coolers already include SecuFirm2™ mounting systems for LGA2011 and can thus be used on LGA2066 motherboards without any upgrades or modifications.

The following models include a mounting-kit for socket LGA2011/2066 and are thus compatible out of the box:

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 where 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.

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).

Is it a problem that the CPU heatspreader is not covered completely by the heatsinkbase on LGA2011-3?

No. Depending on the orientation of the cooler, 1-2mm at the outer edge of the heatspreader may not be covered by the heatsink base. As the heat is concentrated at the center of the CPU and the outermost parts are irrelevant for heat-transfer, this is no problem at all.

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

Pourquoi le fond du refroidisseur Noctua n'est-il pas brillanté et poli ?

Etant donné que la plupart des enthousiastes d'ordinateurs personnels utilise encore aujourd'hui des pâtes thermiques à forte viscosité, le fond du refroidisseur Noctua a été optimisé pour l'utilisation de ces pâtes. Les fines rainures (micro-grooves) dans la surface du fond du refroidisseur Noctua permettent d'appliquer les pâtes thermiques à forte viscosité de manière homogène en une couche ultramince et sans aucune inclusion d'air n'existe entre le refroidisseur et la processeur central. Le risque d'une application non homogène serait beaucoup plus élevé si la surface était brillantée et polie. Des couches de pâte thermique trop épaisses et des inclusions d'air altérant sensiblement la transmission calorifique, les micro-rainures sont d'une importance décisive pour la performance de refroidissement totale du refroidisseur Noctua en cas d'utilisation des pâtes thermiques courantes à forte viscosité.
