Details
14mm Low Profile Design

14mm Low Profile Design

Measuring only 14mm in thickness, the NF-A9x14 is much slimmer than standard 92x25mm fans. This makes it ideal for all applications where standard fans would take up too much space, such as low profile CPU coolers in HTPC builds or server environments.
Flow Acceleration Channels

Flow Acceleration Channels

The NF-A9x14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
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.
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.
Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
SSO2 Bearing

SSO2 Bearing

The NF-A9x14 features 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.
Custom-designed PWM IC with SCD

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the NF-A9x14 uses Noctua's novel, 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 lower speeds.
Low-Noise Adaptor

Low-Noise Adaptor

The NF-A9x14 is supplied with a (L.N.A.) that reduces the maximum fan speed from 2200 to 1700rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control.
Extensive cabling options

Extensive cabling options

The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second NF-A9x14 fan to the same PWM fan header for automatic control.
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 NF-A9x14 features an MTBF rating of more than 150.000 hours and comes with a full 6-year manufacturer's warranty.

NF-A9x14 PWM Review

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.
Test verdict: "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 Review

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.
Test verdict: "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)

NF-A9x14 PWM Review

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.
Test verdict: "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 Review

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.
Test verdict: "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)

Installation Manual (PDF)

Information Sheet (PDF)

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 independent from the second fan’s rpm signal.

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.

Can I disassemble my fan for cleaning?

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 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.

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.

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:

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.

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.

    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).

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

What pin configuration do Noctua 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:
