Le NH-D9L est un ventirad haut de gamme à double batteries à ailettes spécialement conçu pour délivrer un haut niveau de refroidissement malgré une hauteur de seulement 110mm. Son encombrement exceptionnellement faible (15mm de moins que les modèles 9cm classiques tels que le NH-U9S) lui assure non seulement une pleine compatibilité 3U mais permet aussi à ce modèle de parfaitement s’intégrer au sein de HTPC compacts et de boîtiers ayant un facteur de forme réduit où la circulation du flux d’air s’effectue parallèlement à la carte mère. Grâce à un encombrement de 95x95mm, le NH-DL9 n’empiète pas sur les emplacements mémoire ni sur les ports PCIe sur l’ensemble des cartes mères ITX Intel et sur la plupart des modèles pour AMD. Le ventilateur NF-A9 inclus, compatible PWM, permet un pilotage automatique de la vitesse de rotation et donc un fonctionnement étonnement silencieux. Un second NF-A9 optionnel peut par ailleurs être installé, en Dual Mode, pour répondre à un besoin accru de performance le cas échéant. Complété du système de fixation multi-sockets SecuFirm2™, vraie référence haut de gamme dans le domaine, et de la célèbre pâte thermique NT-H1 mais aussi assorti d’une garantie constructeur de 6 ans, le NH-D9L constitue une solution premium très compacte idéale pour les environnements restreints.

Détails
Un ventirad tour de faible hauteur pour un flux d'air optimisé

Un ventirad tour de faible hauteur pour un flux d'air optimisé

Alors que les ventirads de forme plus ramassée soufflent généralement perpendiculairement à la carte mère (en frontal), le NH-D9L est un modèle de type tour soufflant parallèlement à la carte mère. Il offre ainsi un rendement de ventilation meilleur au sein de boîtiers pourvus de ventilateurs en succion (devant) et en échappement (arrière) qui créent un écoulement d'air parallèle à la carte mère.
Compatiblité 3U

Compatiblité 3U

Alors que les ventirads 9cm standards, avec une hauteur de 125mm, sont prévus pour les boîtiers et les racks 4U, le NH-D9L possède une hauteur de seulement 110mm qui lui permet de s'intégrer aux boîtiers 3U. Il constitue ainsi une solution parfaite pour les applications 3U où le niveau sonore reste un sujet sensible (ex : stations de travail audio ou vidéo).
Compatiblité RAM totale

Compatiblité RAM totale

Grâce à son encombrement de 95x95mm, le NH-D9L n'empiète pas sur les emplacements mémoire des cartes mères Intel et AMD actuelles. Cela offre un accès complet aux barrettes de mémoire et assure une compatibilité totale avec les dissipateurs hauts et les ventilateurs optionnels pour mémoire.*
100% compatible avec les cartes PCIe au sein des mini-ITX

100% compatible avec les cartes PCIe au sein des mini-ITX

De nombreuses cartes mères mini-ITX Intel LGA115x possèdent des ports PCIe situés juste à côté de la zone dédiée au socket faisant 95x95mm. Alors que les ventirads excédant cette zone ont tendance à condamner l'usage des ports PCIe, l'encombrement du NH-D9L (95x95mm) lui assure une pleine comptabilité avec les cartes PCIe, en format ATX, microATX ou ITX.
Ventilateur haut de gamme NF-A9

Ventilateur haut de gamme NF-A9

Le ventilateur hautement optimisé NF-A9 se distingue par son cadre AAO Frame ainsi que par les nombreuses optimisations aérodynamiques dont il bénéficie (telles que les Flow Acceleration Channels) qui lui confèrent une efficacité dépassant celle des modèles Noctua 92cm précédents ; d'où une maximisation des performances de refroidissement du NH-D9L.
Compatibilité PWM et adaptateur faible bruit L.N.A.

Compatibilité PWM et adaptateur faible bruit L.N.A.

Le ventilateur NF-A9 92cm fourni avec le NH-D9L est compatible PWM et autorise ainsi un pilotage automatique de la vitesse au travers de la carte mère. De plus, pour un fonctionnement encore plus silencieux, la vitesse maximale de rotation peut être plafonnée de 2000 à 1550 tr./min. grâce à l'utilisation de l'adaptateur L.N.A.
Compatibilité Dual Mode (Double Ventilation)

Compatibilité Dual Mode (Double Ventilation)

Pour satisfaire les utilisateurs désireux de renforcer les performances de refroidissement, le NH-U9L est livré avec un kit additionnel d'agrafes permettant de fixer un ventilateur NF-A9 additionnel sur la batterie à ailettes frontale. Grâce à l'utilisation du câble en Y fourni avec le ventilateur NF-A9 PWM, il est possible de brancher les deux ventilateurs à un seul connecteur de ventilation CPU.**

Garantie Fabricant de 6 ans

Garantie Fabricant de 6 ans

La réputation des ventilateurs Noctua n'est plus à faire tant pour leur qualité que pour leur étonnante longévité. Comme pour tous les modèles de ventilateurs Noctua, le NF-A9 jouit d'un MTTF de plus de 150 000 heures ; la totalité des éléments du package NH-D9L bénéficie d'une garantie fabricant totale de 6 ans.
* Sur certaines cartes mères AMD spécifiques, qui ne respectent pas les normes d’accessibilité définies par AMD (96x114mm), le NH-D9L ne pourra être installé qu’avec des barrettes mémoire n’excédant pas une hauteur de 30mm. Veuillez consulter le tableau détaillé se rapportant à la compatibilité. **Le ventilateur optionnel frontal se loge au-dessus des modules de RAM et en fonction de la hauteur de ces derniers il peut devenir obligatoire de déplacer sensiblement le ventilateur vers le haut. Cette manipulation peut avoir pour effet de dépasser la hauteur de 110mm. De fait, le ventirad pourrait ne plus rentrer au sein d’un boîtier 3U. Ainsi, et afin de garantir une pleine compatibilité 3U en Dual Mode (double ventilation), veuillez n’utiliser que des barrettes n’excédant pas une hauteur de 22mm.

NH-D9L test

When it comes to cooling your system, there are few that do that job better than Noctua. While the cooler may not have had the best cooling performance we’ve ever seen, this much was to be expected, as it is still quite a compact unit. It’s also impressive how many systems this cooler is compatible with, thanks to 100% ram compatibility and a design that shouldn’t conflict with any motherboard VRM, compact and low-profile chassis’ should be an issue and so much more. However, what really shines through is the acoustic performance, as I literally could not hear this cooler running without the fan blades hitting my ears! Obviously, this wasn’t the case after prolonged load on a heavily overclocked CPU, but this cooler wasn’t design for that task anyway. The build quality is as good as it gets and from the contact plate to the tip of the heat pipes, it’s easy to see that a lot of care has gone into the material choices and construction. This is also one of the reasons the price is a bit higher that similar price and performance products, as the Noctua product has a sublime six-year warranty and I’ve no doubt it’ll long outlast even that. The same can be said for the fan, Noctua fans are regarded as some of the finest in the world, it’ll stay cool and quiet for a very long time. If you’re on the market for a compact, powerful, whisper-quiet cooler that doesn’t cost the Earth, then you’ll be very happy with what Noctua have to offer here. It’s a perfect cooler for a non-overclocked CPU, a workstation or office system.
Verdict du test: "Compact, well made and excellent value for money, the Noctua NH-D9L is perfect for those that want a quiet, reliable and widely compatible CPU cooler." (Peter Donnell, eTeknix.com)

NH-D9L test

The Noctua NH-D9L performed very well considering its size being the smallest heatsink in the set. Performance level is very similar to the extremely popular and larger CM Hyper 212+ and dual NH-U9B SE2 in the standardized overclocked test. It placed last in the stock benchmarks but handled overclocks better than the dual-fan NH-U9B SE2 once additional voltage is introduced and the CPU was overclocked. Adding a second NF-A9 fan to the NH-D9L pushed performance closer to the NH-U9S. In terms of noise level, the NF-A9 fan on the NH-D9L is also the quietest and even with the added fan, it is still quieter than the previous generation NH-U9B SE2 which is running at a lower RPM.
Verdict du test: " heatsink with such small footprint is designed primarily to be able to fit in tight-spaced situations unlike regular tower coolers so it will be unfair to just strictly look at the NH-D9L from a cooling performance standpoint but it manages to impress even out of that context. The dual-tower design also allows it to provide superior clearance even compared to the NH-U9S when it comes to either RAM, PCI-E expansion card or MOSFET heatsinks. The NH-D9L also boasts a mere 110mm height clearance which fits under 3U specifications. Coupled with the NF-A9 low noise fan, the NH-D9L not only finds usefulness inside HTPC systems but also noise sensitive audio/video production workstations." (Ron Perillo, Modders-Inc.com)

The Noctua NH-U9S and NH-D9L are welcome additions to the Noctua line of high quality CPU coolers. They expand cooling options for Silent PC enthusiasts seeking smaller quiet systems. Both of these coolers are very close to the size of the long discontinued Scythe Ninja Mini, a unique short tower heatsink in its day. The 110mm and 125mm height clearance and small footprint of these coolers allows them to be used in much smaller cases than tower coolers normally allow. They fare well in comparison to both tower and top-down 120mm fan heatsinks, though they can't challenge the best tested on our LGA1155 platform. The improved performance with an additional fan in push-pull mode at very low noise levels makes these coolers even more versatile. The big plus for the PC builder is that they're almost as low profile as the bigger top-down fan heatsinks, but have the advantage of blowing the heat out towards a nearby back or top panel vent. The efficient evacuation of heat from the case is a key element in quiet PC cooling. We've already used the NH-D9L successfully in such a role in two recent small Gaming Build Guides — Quiet Mini-ITX Gaming Build Guide #2: NCASE M1 Edition and Journey to a Silent MicroATX Gamer. In both of these builds the only other cooler we know of that might have fulfilled the same role is the NH-U9S. The traditional Noctua strengths of excellent secure mounting, ease of installation and thoughtful accessories combine with the absence of any real competition from other brands to make them compelling.
Verdict du test: "[I]f small and quiet is beautiful to you, these new 92mm fan tower coolers from Noctua are tough to beat." (Mike Chin, SilentPCReview.com)

NH-D9L test

En el grafico anterior podemos observar las temperaturas alcanzadas por el Noctua NH-D9L con uno o dos ventiladores. Vemos así como con una temperatura ambiente de 17ºC, alcanzamos los 66.5-67.75ºC bajo carga de trabajo (3.90 GHz) y subimos hasta los 83-84ºC realizando cierto overclocking al procesador (4.20 GHz). Teniendo en cuenta que nuestro i7-4770K es muy muy calentorro, son excelentes temperaturas para mantenerlo bien fresco con un uso convencional.
Verdict du test: "El Noctua NH-D9L es quizás uno de los mejores disipadores compactos que podemos encontrar en el mercado, pues con su altura de tan solo 110 mm permite ser instalado en chasis realmente estrechos. Su rendimiento está a la altura de lo que una marca como Noctua garantiza y más aún su sonoridad, por lo que su única pega puede ser el diseño de los ventiladores que no termina de convencer a todo el público."

NH-D9L test

Für Home-Theater-PCs, Small-Formfaktor-Konfigurationen oder auch kompakte Gaming-Rigs, bei denen das Hauptaugenmerk weniger auf einer High-End-CPU mit allzu hoher TDP liegt, können sowohl der NH-U9S als auch der NH-D9L mit ausgezeichneter Qualität und Verarbeitung punkten, wie wir es von Noctua gewohnt sind. Auch das Gesamtpaket mit einem anpassungsfreudigen PWM-Lüfter, der Möglichkeit einen zusätzlichen Fan problemlos zu integrieren und damit weitere Leistungsreserven auszuschöpfen sowie die Tatsache, dass vom Montagematerial bis hin zu kleinen Details wie einer - "gütig"- mangels anderen Wortes - dimensionierten Einheit Wärmeleitpaste oder dem hochwertigen Case-Badge keinerlei Kompromisse eingegangen wurden, zeichnen die beiden Kühler aus.
Verdict du test: "Auch wenn es sich bei den beiden neuen Kühlern von Noctua um keine Modelle mit brachialer Cooling-Performance handelt, liegen die verzeichneten Temperaturen in einem Bereich, der einige deutlich ausladendere Konkurrenten überflügelt. Zudem muss sich vor Augen geführt werden, in welchen Einsatzgebieten die Verwendung eines derart kompakten CPU-Coolers sinnvoll ist. Die kleinen Würfel machen aufgrund ihrer großen Kompatibilität mit umliegenden Bauteilen des Systems und der besonders im Falle des NH-D9L geringen Bauhöhe vor allem in kompakten Systemen viel her."

NH-D9L test

Der NH-D9L ist unter 7V Lüfterspannung sehr leise, selbst mit einer Doppelbelüftung steigt der Wert auf maximal 36,1dB. Dieser Wert deckt sich 1:1 mit dem des NH-U9S. Unter 12V ist er mit 39,7 respektive 40,9dB bei zwei montierten Lüftern minimal leiser als der Testpartner. Im Gegensatz zum NH-U9S skaliert der Kühler sehr stark mit einem zweiten Lüfter; schade, dass ausgerechnet dieser bei unserem Mainboard die beiden vorderen Ram-Slots blockiert. Auch hier kann die Lüfterdrehzahl durch den beiliegenden L.N.A. auf maximal 1550 Umdrehungen gedrosselt werden. Die CPU erreicht maximal 39 bzw. 34°C bei 7V Lüfterspannung, mit gesteigerter Umdrehungszahl sind es 34 respektive 30°C. Wird die Vcore erhöht und eine Lüfterspannung von 7V gewählt, werden Temperaturen von 61 bzw. 51°C erreicht. Mit 12V sind es nur noch 44 bzw. 41°C. Damit kann sich der NH-D9L einen Platz im oberen Mittelfeld sichern. Neben der ausgewachsenen Kühlleistung und dem umfangreichen Zubehör samt 6 jähriger Garantie und potenter Serienbelüftung erhält der Käufer ein durchdachtes Kühlkonzept, was einen Preis von 50€ rechtfertigt.
Verdict du test: "Noctua hat mit den kompakten Kühlern NH-U9S sowie NH-D9L zwei sehr potente Produkte auf den Markt geworfen, die sich, obwohl sie mit einer Grundfläche von nicht mal 10cm2 ideal für uATX und ITX Gaming Systeme geeignet sind, nicht vor den großen Konkurrenzprodukten – auch aus den eigenen Reihen – verstecken müssen."

NH-D9L test

Frère de l'excellent NH-U9S mais avec une compatibilité serveur 3U le NH-D9L propose une qualité de fabrication tout simplement excellente, le bundle est comme d'habitude très fourni, le montage est très simple grâce au système secufirm2 et la compatibilité mémoire ainsi que le premier port PCIe est totale! Du côté des performances il fait quasiment jeu égal avec le NH-U9S et compte tenu de sa taille s'en sort vraiment très bien, que ce soit avec 1 ou 2 ventilateurs. Les nuisances sonores sont très bonnes à part si le ventilateur est alimenté en 12V, le mode PWM restera le meilleur choix.
Verdict du test: "Le Noctua NH-D9L est un excellent choix lors du montage d'une configuration PC mini-ITX, un HTPC de très petite taille ou encore un serveur au format 3U qui se veut silencieux, du fait de ses très bonnes performances pour sa taille." (Christian Marchini, Conseil Config)

Noctua nous livre une fois de plus du bon Noctua. Le NH-D9L est soigné dans sa conception et offre une finition haut de gamme à l'autrichienne. Pour appuyer le côté premium du ventirad, il est accompagné d'un bundle très complet comme nous l'offre généralement la marque au hibou. Performant, compact et polyvalent, le petit double tour saura prendre soin de votre processeur, qu'il soit utilisé dans un serveur (compatibilité U3), dans une petite station de travail ou dans un home cinéma; sa hauteur ne sera pas contraignante. Nous apprécions toujours autant la facilité d'installation des produits Noctua, la fixation étant très simple à manipuler. Les performances sont excellentes pour ce petit modèle dont les capacités de dissipation max seront limitées à 140W. Au-delà de ce seuil, il sera nécessaire de l'équiper d'un second ventilateur et de l'installer dans un boîtier bien aéré.
Verdict du test: "À l'issue de notre dossier et à la vue de tous les éléments évoqués, nous n'hésiterons pas une seule seconde à gratifier le Noctua NH-D9L de nos 5 étoiles." (Thierry Comtesse, Le Comptoir du Hardware)

D15

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.

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.

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:

NH-C14S
NH-D14 SE2011

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.

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.

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.

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

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 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.

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.

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.

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.

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).

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

Please refer to our socket compatibility chart.

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.

My Intel -K series 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.

Should I take the cooler off before transporting my system?

Due to the low weight of the cooler, it is not necessary to take it off for transport.

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.

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

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

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.

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.

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.

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.
