Digne successeur du célèbre NH-L12, le NH-L12S est un ventirad pour CPU compact et de faible hauteur combinant des niveaux de compatibilité, d’efficacité et de flexibilité étonnants. Grâce à la présence d’un ventilateur faible hauteur au format 120mm (NF-A12x15 PWM,), le NH-L12S offre des niveaux de refroidissement et de silence améliorés par rapport au précédent modèle alors équipé d’un ventilateur 92mm. Mais le NH-L12S est aussi extrêmement modulable : avec le ventilateur installé au-dessus du dissipateur, le ventirad devient compatible avec des modules de RAM pouvant atteindre 48mm alors que l’installation du ventilateur en dessous des ailettes limite la hauteur totale à 70mm et permet au ventirad d’être compatible avec de nombreux boîtiers HTPC et Small Form Factor. Assorti du système de fixation professionnel multi-sockets SecuFirm2™, de la célèbre pâte thermique NT-H1 Noctua ainsi que d’une garantie constructeur complète de 6 ans, le NH-L12S constitue une solution faible hauteur de haut vol pour les plus exigeants.
Le NH-L12S est un ventirad silencieux de taille réduite spécifiquement conçu pour les environnements Small Form Factor et HTPC. S’il offre une performance de premier ordre dans sa catégorie, il n’est néanmoins pas indiqué pour l’overclocking et exige une certaine prudence avec les CPU dépassant une TDP (Thermal Design Power) de 95W. Merci de consulter le guide TDP afin de déterminer si votre CPU est compatible avec le NH-L12S.

Basé sur le célèbre NH-L12

Basé sur le célèbre NH-L12

Avec plus de 200 prix et recommandations de la part de la Presse et des media internationaux spécialisés, le NH-L12 est devenu une référence incontournable dans l’univers des ventirads 120mm puissants de faible hauteur. Pourvu du nouveau ventilateur NF-A12x15, la dernière version (nommée “S”) offre une meilleure flexibilité ainsi qu’une performance accrue en montage « faible hauteur ».
Montage « faible hauteur»

Montage « faible hauteur»

Quand le ventilateur NF-A12x15 est installé sous le dissipateur, le NH-L12S occupe une hauteur de seulement 70mm. Le ventilateur peut être installé dans les deux sens, offrant au choix un flux d’air ascendant ou descendant en fonction de la logique de circulation d’air de votre boîtier.
Montage « grand espace »

Montage « grand espace »

L’installation du ventilateur NF-A12x15 au sommet du dissipateur permet de laisser un espace aéré plus conséquent sous l’empilement d’ailettes. Ce type de montage offre une parfaite compatibilité avec modules de RAM équipés de dissipateurs thermiques hauts de 48mm ainsi qu’avec les dissipateurs de sockets.

NH-L12S test

Новый процессорный кулер Noctua, получивший имя NH-L12S, можно назвать примером того, как надо работать над улучшением продукции. При уменьшенном радиаторе и с использованием лишь одного вентилятора, новинка демонстрирует чрезвычайно высокую эффективность при, не побоимся сказать этого слова, экстремально низком уровне шума! Новинка без проблем может справиться с разогнанным до 5 ГГц процессором Intel Core i7-8700K, что очень и очень хорошо. Благодаря своей конструкции, NH-L12S прекрасно подойдёт для сборки компактной системы с флагманскими комплектующими — высота кулера составляет всего 70 мм, что позволит собрать игровую систему в действительно тонком корпусе.
Verdict du test: "Браво, Noctua! Именно так надо обновлять свои решения!" Владимир Солонин, GreenTechReviews.ru)

NH-L12S test

Noctua propose avec ce NH-L12S de revisiter son NH-L12 premier du nom. Nos tests dévoilent des performances capables de refroidir une puce au TDP de 95 Watts, un Ryzen 5 1600X dans notre cas. La position du ventilateur influe sur les prouesses de l’engin. En mode PWM, nous avons un refroidissement de bonne tenue et silencieux. Sa taille lui permet de s’adresser à des configurations à petit facteur de forme et 45 mm peuvent être libérés pour l’usage de barrettes mémoire hautes. Ses prestations ne le positionnent pas sur le haut du tableau en matière de refroidissement mais cela n’est pas son objectif. Noctua le précise en soulignant que l’overclocking n’est pas conseillé.
Verdict du test: "Le but de ce NH-L12S est de proposer de la compacité et un refroidissement silencieux. Affiché à 49, 90€ , l’objectif est atteint." (Jérôme Gianoli, GinjFo.com)

NH-L12S test

Najniższe obroty jakie uzyskałem to 950 RPM dlatego to właśnie na nich przeprowadzone zostały także testy. Chłodzenie wypada w nich lepiej niż się spodziewałem. NH-L12S spokojnie da sobie radę z lekko podkręconym procesorem, nawet na najmniejszych obrotach. Wtedy też jest konstrukcja jest niesłyszalna. Obroty 1400 RPM to pewien kompromis pomiędzy wydajnością a kulturą pracy a 1850 RPM to zdecydowanie tryb wydajnościowy – jest wtedy głośno.
Verdict du test: "Jest to świetne chłodzenie dla komputerów typu SFF albo HTPC." (Michał Andruszkiewicz, WhatNext.pl)

Для оценки эффективности Noctua NH-L12S мы использовали Intel Core i7-7740X с TDP 112 Вт. Обозреваемый кулер без проблем справился с охлаждением 4-ядерного камня в номинальном режиме. Вентилятор NF-A12x15 PWM не разгонялся выше 1400 об/мин, это бесшумный формат работы.
Verdict du test: "Новинку от австрийского производителя премиальных систем охлаждения стоит рекомендовать для установки в любой, даже самый миниатюрный корпус, и для отвода тепла от производительных камней, в том числе Intel Core i7 и AMD Ryzen 7, главное не прибегать к разгону."

NH-L12S test

Wenn das Gehäuse nicht ganz so limitiert und wir zu einer etwas größeren Kühllösung greifen können, denn kommt der NH-L12S ins Spiel. Im High Clearance Mode kommt er auf nur 70 mm Höhe und danke des SecuFirm2 Montagesystem ist er ebenfalls schnell und einfach montiert. Klar dauert es etwas länger als beim L9a, aber dafür haben wir hier den Support von Intel und AMD Systemen und können kostenlos auf neuere Sockel upgraden. Die Temperaturen werden sehr niedrig gehalten und dank des mit 15 mm besonders flachen 120 mm Lüfters auch leise erreicht. Im high Clearance Mode, mit dem Lüfter auf dem Kühler, sind sowohl die Temperaturen, als auch die Geräuschemissionen dazu noch etwas besser – etwas höhere RAM Module werden so auch möglich.
Verdict du test: "Insgesamt ein sehr ausgewogenes Paket, bei dem wir rein gar nichts zu beanstanden haben." (Dennis Heinze, hardwarepoint.net)

NH-L12S test

Aki olcsó processzorhűtőt szeretne kompakt számítógépéhez beszerezni, hisz egy modellért 16 ezer forintnál is többet kérnek el (ami viszont Noctua márka alatt nem számít soknak). De aki egy csendes megoldásra vágyik és komolyabb, akár Core i7-es, vagy AMD Ryzen processzort használ és nem sajnál ekkora összeget kiadni, annak mindenképp csak ajánlani tudjuk (már a 6 év garancia miatt is) az NH-L12S beszerzését.
Verdict du test: "A Noctua ismételten szép munkát végzett, hisz nem egy újabb, palettát gyarapító modellt dobott piacra, hanem a hűtő bevezetését azzal a céllal lépte meg, hogy egy újabb prémium kategóriás megoldással örvendeztesse meg a vásárlókat." (Kocsis Bence, Rendszerigény.hu)

Mit einem Blick auf die erreichten Temperaturen kann man aber mit Gewissheit sagen, dass der NH-L12S in der Lage ist, auch mit einer recht potenten CPU zurechtzukommen. Einzig Übertaktungsversuche sollte man mit diesem Kühler sein lassen.
Verdict du test: "Durch den besonders flachen Lüfter, welcher seitens Noctua auf dem NH-L12S eingesetzt wird, kann der Kühler bei den gleichen Platzverhältnissen eine bessere Kühlleistung erzielen, als es noch sein Vorgänger mit einem verbauten 92-mm-Lüfter konnte." (Patrick Seus, mod-your-case.de)

Testler esnasında AMD Ryzen 1800X işlemci normal, webde gezinirken ile oyun oynarken ve 3D Mark testlerindeki sıcaklık değerlerini amd'nin wraith soğutucusu ile karşılaştırarak gözlemledim. Küçük yapısı, ince radyatörü ve fanına göre kaslı amd wraith soğutucuya göre biraz daha başarılı olan soğutucu beni oldukça şaşırtdı. Aslına bakarsanız biraz geride kalacağını düşünmüştüm. Birde noctua soğutucunun gürültü seviyesinin daha düşük olduğunu unutmayalım.
Verdict du test: "Noctua NH-L12S işlemci soğutucusu fanı, 4 adet bakır ısı boruları ve kaliteli ısı tabanı sayesinde iyi performans gösterirken, oldukça da sessiz görevini yerine getiriyor. Ayrıca Mini ITX, HTPC kasa kullanıcılarına çok iyi bir çözüm sunuyor. " (Murat Yildirim, Turkchip.com)

NH-L12S test

Come avete potuto vedere il nuovo dissipatore Noctua NH-L12S, è capace di far fronte ad un buon overclock tenendo le temperature nella norma e dando la possibilità di spingere ancora più in la CPU praticando anche un leggero overvolt. Le temperature registrate vanno a confermare l’ottima costruzione e l’ottimo utilizzo dei materiali, non ché la loro qualità.
Verdict du test: "Per tanto non possiamo che consigliarlo a chi vuole un ottimo dissipatore da montare in un Mini-PC o in un HTPC, senza rinunciare alle prestazioni ed utilizzarli anche per il gaming." (Da Igor Lucifaro, HardwareMAX.it)

NH-L12S test

O Noctua NH-L12S é um cooler com um preço aproximado de 50€ com uma ventoinha slim PWM de 120 mm. Tem grande compatibilidade com os sockets da Intel e AMD, incluindo o mais recente AM4. É um cooler de baixo perfil com apenas 70 mm de altura, boa qualidade de construção e instalação fácil graças ao sistema SecuFirm2. Os resultados estão dentro do esperado para um cooler deste género, contudo, como foi possível ver nas temperaturas quando o CPU está em stress, não é apropriado usar este cooler em sistemas com overclock.
Verdict du test: "O Noctua NH-L12S é uma alternativa nas caixas estreitas onde não cabem os tradicionais coolers de 120 mm e onde o silêncio é importante." (João Teixeira, JotaReviews.pt)

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.

In which orientation should top-flow coolers (NH-C series, NH-L12) be installed?

When using top-flow coolers in a tower-style case, we strongly recommend installing the cooler with the heatpipes in horizontal position or with the bends of the heatpipes pointing downwards. Please avoid installing the cooler with the bends pointing upwards as this may result in reduced cooling performance. In desktop cases, the cooler can be used in any orientation.

Orientation

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.

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.

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

Please refer to our socket compatibility chart.

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.

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.

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 AMD AM4 (Ryzen)?

The following models include a mounting-kit for socket AM4 and are thus compatible out of the box:

NH-D15 SE-AM4
NH-U12S SE-AM4
NH-L12S
NH-L9x65 SE-AM4

The following models are not compatible with the AM4 socket and can not be upgraded:

NH-U12DO A3
NH-U9 DO A3

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:

NH-C14S
NH-D14 SE2011
NH-D15
NH-D15S

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).
