Award-winning NF-F12 design

Award-winning NF-F12 design

Having received more than 150 awards and recommendations from the international press, Noctua's NF-F12 has become a proven premium choice for 120mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
chromax.black.swap edition

chromax.black.swap edition

Maximising colour choices, Noctua’s chromax.black.swap edition fans can be colour-customised using the included swappable anti-vibration pads as well as optional anti-vibration mounts and cables. This makes them ideal for enthusiasts looking for true premium-grade fans that can be colour-coordinated with popular build themes such as all black, black & white or black & red.
Swappable anti-vibration pads in 6 colours

Swappable anti-vibration pads in 6 colours

The NF-F12 PWM chromax.black.swap comes with 4 black, white, red, blue, green and yellow NA-AVP1 anti-vibration pads respectively. By combining the various colours with black or leaving off the pads on one side, the fan can be coordinated with most popular build colour schemes out of the box. Additional NA-SAVP1 sets for outfitting both sides in one colour can be purchased separately.
Heptaperf™ Impeller

Heptaperf™ Impeller

Custom designed for the new Focused Flow™ frame and to work in tandem with the eleven stator guide vanes, the NF-F12's seven blade Heptaperf™ impeller has been carefully optimised to achieve a perfect balance between power and quietness.
Optional coloured cables

Optional coloured cables

Noctua’s chromax line fans use a modular cabling system and come pre-fitted with a fully sleeved black NA-EC1 30cm cable. For refined colour coordination, white, red, blue, green and yellow 30cm NA-EC1 cables plus corresponding NA-YC1 y-cables are available separately.
Optional coloured anti-vibration mounts

Optional coloured anti-vibration mounts

To complement the coloured anti-vibration pads included with the fans, users can purchase chromax line NA-SAV2 anti-vibration mounts that enable the convenient, quick and vibration-free installation of fans in standard mounting holes for case fans.
Focused Flow™ frame

Focused Flow™ frame

Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flow™ frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-F12 to rival the performance of conventional fans running at much faster speeds.
AAO frame

AAO frame

Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
Varying Angular Distance and Vortex Control Notches

Varying Angular Distance and Vortex Control Notches

The NF-F12's stator guide vanes are set out in Varying Angular Distance and feature Vortex-Control Notches. Both measures help to spread the noise emission over a broader frequency spectrum and thus make the fan's sound pattern more agreeable to the human ear.
Stepped Inlet Design

Stepped Inlet Design

Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.
Inner Surface Microstructures

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
SSO2 bearing

SSO2 bearing

The chromax line fans feature the further optimised second generation of Noctua’s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
Metal bearing shell

Metal bearing shell

In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the chromax edition fans sport a CNC milled bearing shell made entirely from brass.
Custom-designed PWM IC with SCD

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the chromax edition fans use Noctua’s custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the chromax edition models feature an MTBF of more than 150,000 hours rating and come with a full 6-year manufacturer's warranty.

NF-F12 PWM chromax.black.swap Review

Svi testirani ventilatori imaju ram izrađen od kvalitetne plastike, sa „stepenastim“ oblikom koji smanjuje turbulencije. Svaki se oslanja na nove SSO2 lagere, što im omogućava tih i efikasan rad uz dug životni vek od 150.000 časova. Svaki od ovih modela stigao je u Chromax paketu jer koliko god da su ovi ventilatori funkcionalni i kvalitetni, neki korisnici jednostavno ne vole kombinaciju crne i braon boje. Za one koji ne žele da stavljaju ventilatore sa braon detaljima u svoje novo crno‑crveno kućište, gde je svaka komponenta prilagođena upravo toj kolornoj šemi, Noctua je ponudila novu liniju Chromax dodataka.
Test verdict: "Noctua je oduvek imala specifičnu kolornu šemu koja nije bila po ukusu svakoga i zbog toga je bilo vreme da se kompanija prilagodi tržištu. U skladu s tim, sada možete da imate Noctua kuler bez bež i braon nijansi, što će svakako obradovati estetski orijentisane korisnike, koje je možda samo to sprečavalo da ugrade neki od ovih proizvoda u svoje kućište."

NF-F12 PWM chromax.black.swap Review

Der Chromax NF F12 Lüfter wird in einem Dreiergespann getestet und muss gegen zwei starke Konkurrenten antreten. In vier Einstellungen geht der 120 mm Chromax Lüfter als Sieger hervor. Auch die Gesamtwertung im Bereich der Temperaturen kann sich dieses Beast holen. Der Chromax NF A14 ist gegen den mitgelieferten Eiswind 140 von Alphacool angetreten und schaffte es diesen doch sehr guten Lüfter mit minimalen aber dennoch niedrigeren Temperaturen, zu unterbieten.
Test verdict: "Die neue Noctua Chromax Serie überzeugt uns. Wir wurden nicht enttäuscht und freuen uns auf weitere Erneuerungen. Die Kabel sind gut und sicher zu verlegen und haben eine durchweg hohe Qualität. Die Anschlüsse sind sauber und die Sleeves werden ihrem Eindruck gerecht. Die Chromax Lüfter sind wirklich sehr gut und machen ihren Job perfekt. Kaum ein Lüfter kann eine so ausgewogene Leistung bieten." (Dennis Trägner, hardwareinside.de)

NF-F12 PWM chromax.black.swap Review

Noctua étoffe largement sa gamme Chromax et ce n’est pas pour nous déplaire que cette dernière intègre maintenant quelques ventilateurs. Certes les ventilateurs Noctua ont une sacré réputation associant des performances à un niveau sonore relativement bas mais surtout à une très bonne fiabilité. Mais la ou plutôt le duo de couleurs d’origine se révèle être un frein pour des potentiels acheteurs… La gamme Industrial PPC propose d’ors et déjà des ventilateurs arborant une tenue noire, même si les silentblocs restent de couleur marron … Mais c’est surtout leur vitesse de rotation élevée qui engendre un niveau sonore conséquent (même si nous pouvons toujours adapter leur vitesse de par une gestion PWM). Aujourd’hui nous disposons d’un panel de 4 ventilateurs issus de la gamme « classique » des ventilateurs Noctua. [...] La gamme Chromax a débuté avec des silentblocs colorés ainsi que des attaches souples du même ordre. Avec ses nouveaux ventilateurs, Noctua équipe ces derniers d’un lot de silentblocs proposant ainsi chacune des couleurs (Noir, Blanc, Bleu, Rouge, Vert et Jaune). Cependant, mis à part le NF-A15 HS PWM, nous n’avons qu’un jeu de 4 silentblocs de chaque couleur ne permettant d’équiper qu’une seule face du ventilateur. Alors, avons nous besoin d’équiper les 8 coins du ventilateur avec la même couleur? Ou pouvons nous simplement mettre les noirs du coté radiateur et laisser la couleur sur la face opposée? La question reste dans le domaine esthétique et donc totalement subjective… Il reste que Noctua propose toujours à la vente séparée les kits NA-SAVP1 contenant 16 silentblocs de même couleur. On apprécie le système de câblage modulaire présent sur cette nouvelle gamme de ventilateurs. Cela permet de troquer l’extension de couleur noire incluse dans le bundle par une extension (NA-SEC1) adoptant la couleur des silentblocs que l’on a choisi de mettre en place. Voire de mettre directement en place l’adaptateur en Y que propose les kits NA-SYC1, utile dans le cas d’un ventirad comportant deux ventilateurs. La cerise sur le gâteau du geek est que la gamme Chromax propose aussi d’habiller deux des nombreux ventirads Noctua : NH-U12S et NH-D15 et les versions qui se déclinent de ses produits. Car il est un « défaut » esthétique qu’ont tous en commun ces ventirads, c’est l’extrémité des caloducs qui émergent de la dernière ailette… Avec le carénage que propose Chromax, on habille littéralement le radiateur d’une robe noire ou blanche avec ou sans petites touches de couleur. On peut même laisser libre cours à notre imagination pour remettre une seconde couche de peinture sur la base poudrée dont est revêtue la structure en aluminium, histoire de pousser encore plus loin la personnalisation !!! Amis artistes, à vos pinceaux… On rajoute que le montage est simple tout en étant efficace donc que du bon.
Test verdict: "Après quelques « hésitations » en nous présentant sa gamme Redux ou Industrial, Noctua élargit sa gamme Chromax à quelques uns de ses ventilateurs en les habillant d’une robe entièrement noire ! Mais on ne s’arrête pas là car cette gamme Chromax touche aussi des câbles ainsi que certains ventirad…." (Bertrand Curras, modding.fr)

NF-F12 PWM chromax.black.swap Review

A Noctua tipikusan az a gyártó, aki nem úszik az árral, ha a szükség úgy hozza. A folyadékhűtéses megoldások megjelenésével nem próbálta felvenni a harcot a konkurens gyártókkal, hanem inkább a meglévő léghűtéses processzorhűtőit tökéletesítette annak érdekében, hogy a vásárlók igényeit maximálisan kielégítsék. A komplett processzorhűtők mellett a ventilátorok terén is sokak számára bosszankodásra adott okot, hogy a kezdetek óta barna színösszeállítást használja a gyártó. A Noctua aztán engedett a gyeplőn és piacra dobta Redux sorozatát, valamint az industrialPPC sorozatét, mely színben eltért a megszokottól.
Test verdict: "Ezen is tovább lépve aztán létrejött a chromax elnevezés, mely olyan termékeket gyűjt össze melyekkel más színbe öltözhetnek a processzorhűtők, ventilátorok és egyéb kiegészítők." (Kocsis Bence, Rendszerigény.hu)

Information Sheet (PDF)

Can I use the NF-F12 in push/pull configurations?

Yes, the NF-F12 can be used in push/pull setups. However, the NF-F12 at full speed produces so much static pressure that even a single fan can push the air through fin-stacks with wide to medium fin spacing (such as the one of the popular Noctua NH-U12P heatsink) very effectively. In these cases, adding a second NF-F12 fan for a push/pull setup may not provide significant improvements in performance over a single NF-F12. We thus only recommend push/pull setups on heatsinks or radiators with denser fin stacks or if you plan to run the NF-F12 fans at slower speeds (e.g. via the supplied L.N.A. and/or PWM control).

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?

Noctua 12V fans comply with the established specifications for standard PC systems issued by Intel and AMD. Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often deviate from these specifications e.g. by using proprietary fan headers, custom pin-alignments or pin-configurations, different methods of fan speed control, etc. This can lead to compatibility issues when using Noctua fans in systems from said brands. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues (e.g. errors or shutdowns due to low fan speed) can often not be resolved. As a result, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

Can Noctua fans be used to replace noisy stock fans in NAS devices?

Noctua fans such as the 40, 60, 80 or 92mm NF-A series models are ideal for replacing noisy stock fans in NAS devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their NAS units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their NAS device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing NAS fans are:

  • Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some NAS units use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your NAS device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
  • Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some NAS units use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your NAS device uses the same pin functions.
  • Firmware speed control: Some NAS devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
  • Different starting voltage: Most NAS devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the NAS device to display errors or even shut down because it suspects a fan failure.
  • Different power draw: Some NAS devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.

Please note that most NAS manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. For example, there are excellent video tutorials available for changing the fans in popular Synology NAS models (DS416j, DS1515+ and DS1812+ in English, DS416/DS415/DS916/DS216/DS214 and DS1515+ in German). Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your NAS fan are applicable to your specific model as well as your specific hardware and firmware revision.

Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their NAS fans. Please note that since there are so many different NAS models and most of them lack documentation for aspects such as fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing NAS fans. Please contact your NAS manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.

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 check if my 4-pin fan header supports PWM?

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).

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:

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:

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.

How should I clean my Noctua fan?

Fans inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fans regularly 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.
In order to ensure flawless operation over many years of usage, Noctua’s premium grade SSO bearings are fully sealed to prevent the entering of fine dust particles. Please 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.

How can I find out the direction of airflow and sense of rotation?

When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:

What pin configuration do Noctua 12V fans use?

All Noctua fans feature the standard pin-configurations set out in the Intel and AMD specifications. These standard pin-configurations are used on most mainboards and fan controllers today:

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.

Can I run 4-pin PWM fans on 3-pin fan headers?

PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though. When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).

Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?

In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please 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.

It is thus recommended to clean your fans 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 don’t use a vacuum cleaner as this may apply excessive force to the fan.

Can I use Low-Noise Adaptors with y-cables / multiple fans?

Yes, Low-Noise Adaptors (L.N.A.s) can be used with y-cables, but please make sure to use one L.N.A. per fan and to place the L.N.A.s between the y-cable and the fans as shown below. Never use one L.N.A. for two (or more fans) by placing it between the mainboard and the y-cable!

D15S

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

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

Can I paint my Noctua fan in order to change its color?

Since even small variations in the layer of paint can lead to an imbalance of the impeller, resulting in vibrations, higher noise levels, increased stress on the bearing and thus reduced lifespan, we do not recommend painting the fan. Please note that for the reasons stated above, painting the fan will void your warranty.

Can I use the fan with all-in-one watercooling solutions?

Yes, this fan is ideally suited for use with all-in-one watercooling solutions. However, please note that some of these coolers use proprietary methods for automatic fan speed control which can lead to problems with speed control when using fans other than the stock one. Should you experience any problems with automatic fan speed control when the fan is connected to the fan header of your watercooling solution, please simply connect it directly to your mainboards CPU fan header instead.

Can Noctua fans be used to replace noisy stock fans in switches, routers or other network devices?

Noctua fans such as the 40, 60, 80 or 92mm NF-A series models are ideal for replacing noisy stock fans in switches, routers and other network devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their network device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing pre-installed fans are:

  • Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some network devices use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
  • Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some network devices use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your device uses the same pin functions.
  • Firmware speed control: Some network devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
  • Different starting voltage: Most network devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the device to display errors or even shut down because it suspects a fan failure.
  • Different power draw: Some network devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.

Please note that most network device manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your fans are applicable to your specific model as well as your specific hardware and firmware revision.

Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their pre-installed fans in network devices. Please note that since there are so many different devices and most of them lack documentation for aspects such as fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing pre-installed fans. Please contact your network device manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.
