Détails
Conception faible épaisseur de 14mm

Conception faible épaisseur de 14mm

Avec une épaisseur de seulement 14mm, le NF-A9x14 est bien plus mince que les ventilateurs standards 92x25mm. Il devient ainsi le choix de prédilection pour les situations ne permettant pas, pour des raison d'espace, la mise en place d'une ventilateur standard, ce qui est le cas par exemple des ventirads pour CPU de petites taille équipant les HTPC ou les serveurs.
Canalisateurs de flux (Flow Acceleration Channels)

Canalisateurs de flux (Flow Acceleration Channels)

La turbine du NF-A9x14 est munie de canalisateurs de flux sur la face succion du ventilateur. L'accélération du flux générée aux extrémités des pales permet de créer une succion plus massive, moins dispersée, et accroit ainsi l'efficacité tout en réduisant les perturbations sonores liées aux vortex.
Cadre AAO

Cadre AAO

Les cadres AAO (Advanced Acoustic Optimisation) de Noctua sont équipés de silentblocs anti-vibrations et bénéficie d'optimisations exclusives permettant de repousser encore plus loin les limites de la performance et du silence : Stepped Inlet Design and Inner Surface Microstructures.
Conception en escalier de l'admission

Conception en escalier de l'admission

La conception en escalier de l'admission de Noctua ajoute une turbulence au flux entrant permettant ainsi un passage progressif d'un flux laminaire à un flux turbulent. Ce phénomène réduit les émissions sonores initiales, améliore la cohésion du flux et augmente la capacité de succion en particulier dans les environnements où l'espace fait défaut.
Conduit de contournement à microstructures

Conduit de contournement à microstructures

Les extrémités des pales évoluant à proximité de la surface intérieure du conduit (caractérisée par la présence d'une microstructure), la séparation des flux qui s'opère au niveau de la succion est quasi inexistante. Cette optimisation permet de réduire les émissions sonores liées au mouvement des pales, améliore le flux d'air ainsi que le niveau de pression.
Silentblocs anti-vibrations intégrés

Silentblocs anti-vibrations intégrés

Les silentblocs anti-vibrations intégrés, fabriqués à partir de silicone extra-souple, permettent de limiter la transmission des vibrations minute tout en assurant une parfaite compatibilité avec les vis et systèmes de fixations standards.
Roulement SSO2

Roulement SSO2

Le NF-A9x14 se voit doté de la célèbre référence du roulement Noctua : le SSO. Il s'agit ici de la toute nouvelle génération, encore plus optimisée. Le SSO2 est en effet équipé d'un aimant arrière plus proche de l'axe pour une meilleure précision, longévité et stabilité.
Circuit PWM exclusif doté du SCD

Circuit PWM exclusif doté du SCD

Permettant un pilotage automatique complet de la vitesse en PWM, le NF-P12 PWM utilise le tout nouveau circuit exclusif NE-FDI PWM qui intègre la technologie SCD (Smooth Commutation Drive). En favorisant des impulsions moins brutales au niveau du couple, le SCD élimine les bruits de commutation et permet ainsi au ventilateur de rester plus silencieux à faible vitesse.
PWM à 0%: arrêt

PWM à 0%: arrêt

Lorsque le ventilateur est réglé sur un rapport de cycle PWM de 0%, que ce soit via la carte mère ou un contrôleur de ventilation PWM, il s’arrête. Ceci permet de créer des configurations avec un refroidissement semi passif qui permet l’arrêt automatique des ventilateurs – pour assurer ainsi un fonctionnement totalement silencieux – en fonction des sollicitations et des niveaux de température.
Adaptateur faible bruit

Adaptateur faible bruit

Le NF-A9x14 PWM est livré avec un adaptateur L.N.A. qui permet de réduire la vitesse maximale de 2200 à 1700rpm. L'adaptateur L.N.A. peut être utilisé afin de rendre la vitesse de ventilation stabilisée à 1700 rpm ou bien de brider la vitesse lors d'une utilisation en pilotage PWM.
Nombreuses options de câblage

Nombreuses options de câblage

Si le câble principal d'alimentation du ventilateur est court (20 cm) afin de limiter l'encombrement dans les utilisations traditionnelles, celui de 30cm est fourni pour résoudre les problèmes éventuels de distance. Les deux câbles sont gainés et un câble en Y (4 broches) autorise le branchement d'un PWM additionnel au même connecteur pour un pilotage automatique.
Garantie Constructeur de 6 ans

Garantie Constructeur de 6 ans

Les ventilateurs Noctua sont connus pour leur qualité irréprochable et leur étonnante longévité. Comme tous les ventilateurs de la marque, le NF-A9x14 PWM affiche un MTTF de plus de 150 000 heures de test et se voit assorti d'une garantie constructeur de 6 ans.

Cijene manjih (A4x10/A6x25/A9x14 – 12,90/14,90/16,90€), kao i većih 140mm modela (21,90€) su uglavnom u skladu s dosadašnjom politikom Noctua proizvoda, koja se i dalje bazira na principu – kvaliteta prije svega, uz odgovarajuću cijenu. Nakon svega viđenog, zaista im ne možemo puno zamjeriti na tome, s obzirom na sve prednosti njihovih proizvoda iz nove A-serije za koje imamo gotovo isključivo riječi hvale.
Verdict du test: "Noctua nam je ovom prilikom priredila mnoga iznenađenja po pitanju novih proizvoda raznih veličina i namjena. Od minijaturnog 40mm A4x10 modela, preko A6x25 i A9x14, pa sve do 140mm inačica, svaki od testiranih ventilatora odaje onu poznatu Noctua kvalitetu i uglađenost u radu uz visoku funkcionalnost i bogatu dodatnu opremu. Za svakoga ponešto, bi možda bio najslikovitiji opis nove A-serije ventilatora, a što se nas osobno tiče, itekako bismo voljeli vidjeti par 140mm ULN modela i u našem testnom računalu. Za korisnike koji zahtijevaju veliku efikasnost i relativno umjeren nivo buke, tu su naravno A14 FLX i A15 PWM modeli, koji svojom fleksibilnošću, elegantnim radom ali i visokom kvalitetnom izrade itekako zaslužuju našu preporuku."

NF-A9x14 PWM test

Ξεκινώντας από τον "μεγάλο" της παρέας, ο NF-A9x14 ήταν ο ανεμιστήρας που ξεχώρισα από την πρώτη στιγμή. Η διάμετρός του ανέρχεται στα 92mm, αλλά το συνολικό του μέγεθος είναι αυτό που κερδίζει τα βλέμματα, καθώς οι διαστάσεις του ανήκουν στην κατηγορία ... "Super-Slim". Ναι, το ύψος του συγκεκριμένου ανεμιστήρα, μαζί με το πλαίσιό του φτάνει στα 1,4 cm! Ταυτόχρονα, υπόσχεται βέλτιστη στατική πίεση μέσω της ιδιαίτερης σχεδίασής του ανεμιστήρα και των flow drivers του. Παράλληλα, ο sleeved bearing μηχανισμός τους εγγυάται πρακτικά αθόρυβη λειτουργία στα 19,9 dB, διατηρώντας έναν χαμηλό ρυθμό περιστροφής με μέγιστο τις 2220RPM στα 12v, και όλα αυτά με υπολογισμένη διάρκεια ζωής (MTBF- Mean Time Between Failure) που αγγίζει τις 150000 ώρες - περίπου... 17 χρόνια 24/7 λειτουργίας θα χρειαστείτε μέχρι να χρειαστεί να τον αντικαταστήσετε. Ο συγκεκριμένος ανεμιστήρας έρχεται να σπάσει πολλά από τα "ταμπού" και τους μύθους που κυκλοφορούν γύρω από την αγορά ανεμιστήρων και συστημάτων ψύξης- ένας από τους οποίους είναι ότι μόνο ανεμιστήρες > 14cm εγγυώνται αθόρυβη λειτουργία και χαμηλό ρυθμό περιστροφής, για να μπορέσουν να "σπρώξουν" αρκετά λογική ποσότητα αέρα εντός του συστήματος.
Verdict du test: "Αν υπήρχε κάποιος από τους τρεις ανεμιστήρες που ξεχώρισα, αυτός είναι ο Noctua NF-A9x14 PWM, ο 92mm ανεμιστήρας που είχαμε στην διάθεσή μας. Δεν είναι μόνο το γεγονός μόνο ότι μπορεί να κάνει τα καταφέρνει εξαιρετικά σε θέματα απόδοσης και θορύβου, αλλά συνδυάζει και ένα super-slim profile το οποίο θα βοηθήσει την κατάσταση αρκετά ειδικά αν το σύστημά σας είναι αρκετά... "στριμωγμένο"! Η χρήση για μένα, μετά το πέρας των δοκιμών, ήταν να τον ενσωματώσω σε ένα Bitfenix Prodigy White σύστημα, στο οποίο η προσωπική μου ανοχή στον θόρυβο που παράγει είναι μηδενική! NF-A9x14 PWM με ικανοποίησε απόλυτα στο θέμα του θορύβου, σε σημείο που στα 7V δεν μπορεί κάποιος να ακούσει αν λειτουργεί ή όχι!" (Vasilis Galiouras, HWBox.gr)

Hemos probado los tres ventiladores y gratamente nos ha sorprendido su bajo nivel de ruido generado. El modelo de A4x10 es el único mínimamente más audible, pero por sus altas revoluciones es normal. Los modelos de 40 y 60 mm son perfectos para sistemas embebidos que requieren un ventilador para la extracción de aire, así como para los amantes del modding que deseen refrigerar zonas de su PC de menor superficie. El modelo de 90 mm es ideal para equipos HTPC con disipadores de perfil bajo, que lo verán aún más reducido al cambiar los habituales ventiladores de 25 mm de grosor por este de 14 mm.
Verdict du test: "Los ventiladores Noctua Serie-A ofrecen en formato compacto el rendimiento esperado por un ventilador de esta prestigiosa marca: gran flujo de aire a un mínimo nivel sonoro. Su uso está limitado a necesidades concretas, por lo que gran parte de los usuarios no tendrán necesidad de ellos. Sin embargo, los que requieran productos de estas dimensiones agradecerán en gran medida el lanzamiento de estos ventiladores tan eficientes por parte de Noctua."

NF-A9x14 PWM test

Malgré la taille qui présageait des nuisances sonores horribles comme nous avons tous l'habitude d'entendre venant de ventilateurs comme ceux-ci, et bien il n'en est rien! Le ventilateur qui me faisait le plus peur était le tout petit Ax410, un ventilateur de 4cm qui, tournant à 4500 RPM, me donnait mal aux oreilles avant même de le brancher, mais au final il se révèle être extrêmement silencieux, du très bon pour Noctua qui pourra enfin vous réconcilier avec vos appareils utilisant des ventilateurs de cette taille. Le A6x25 est le plus silencieux du lot, il n'y a aucun bruit parasite audible et il saura se faire discret même au maximum. Le A9x14, qui n'est autre qu'un ventilateur 92 mm au format "low profile" est un modèle qui est très intéressant si vous êtes en manque de place dans vote HTPC (ou tout autre boitier avec peu de place), il a une grande plage d'utilisation et saura se faire très discret, à noter qu'il émet un léger son aigu à plein régime.
Verdict du test: "Que dire de cette série un peu spéciale de chez Noctua? Au départ un peu sceptique quant au bruit que génèrent généralement ces types de ventilateurs il faut avoué que j'ai été agréablement surpris. [...] si vous cherchez à remplacer un ventilateur criard (par exemple dans un switch, ou un NAS etc..) par un silencieux vous avez trouvé ce qu'il vous faut!" (Christian Marchini, Conseil Config)

Can Noctua fans be used to make the Anycubic I3 Mega 3D printer run more quietly?

Yes, many users of the Anycubic I3 Mega have successfully used Noctua fans for reducing the noise emission of this 3D printer. In particular, the following three modifications have been reported to work well and make the printer much quieter in operation:
  1. Replacing the hot-end fan with the NF-A4x10 FLX as described here or here.
  2. Replacing the power supply fan with the NF-A9x14 PWM using a custom 3D printed casing for the power supply as shown here or here (also see this PSU cover for the NF-A6x25).
  3. Replacing the motherboard fan with the NF-A9x14 PWM using a custom 3D printed fan holder frame (also see this mainboard fan holder.

Disclaimer: While many users have reported good results, Noctua can not verify and assumes no liability regarding the correctness of the information contained in such user reports, videos or tutorials. Noctua can generally give no guarantee that a certain fan will work with a specific third-party device because usually, there is no detailed specification regarding fan compatibility and control available for such devices. 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 pre-installed fans in third party devices and that special care is exercised when handling sensitive components such as power supplies. Please note that since there are so many different devices and most of them lack detailed documentation for fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing pre-installed fans. Please contact your device manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control. The pin configuration of Noctua fans is detailed in this FAQ. Noctua can not be held responsible for any damage or losses that may occur when replacing fans in third party devices.

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.

How much torque should be used for fan screws?

Please use 0.6Nm to tighten fan screws. Make sure not to overtighten the screws as this may damage the fan frame.

Where can I find a technical documentation and specifications of the PWM speed control system of Noctua’s fans?

While using PWM (Pulse Width Modulation) based fan speed control in PC environments is usually straightforward and does not require any background knowledge, it can be vital when it comes to controlling fans via PWM in other environments. Please refer to our specification white paper for a detailed technical documentation of the PWM speed control features of Noctua’s 4-pin PWM fans. Detailing aspects such as connector types, pin configuration or RPM speed signal output as well as signal specifications and circuit design questions, it enables engineers to implement PWM based speed control for Noctua fans in custom circuit designs and applications.

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

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

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 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.

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

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

Unfortunately there is usually no option to set a lower minimum value in the BIOS that would suit the low minimum speed of Noctua PWM fans. The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

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.

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!

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.

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.

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:

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 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.

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

Noctua fans such as the 40, 60, 80, 92 or 120mm 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:
