Next-generation performance

Next-generation performance

Noctua’s 120mm fans such as the NF-F12 and NF-S12A are renowned as being among the best on the market and have received more than 400 awards and recommendations from the international press. With its further improved efficiency and novel, state-of-the-art engineering, the NF-A12x25 represents another step up in performance and manufacturing.
Highly optimised P/Q curve for all applications

Highly optimised P/Q curve for all applications

The NF-A12x25’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.
Excellent on-application acoustics

Excellent on-application acoustics

While many fans produce unpleasant, high-pitched noises when installed in typical applications such as on heatsinks or radiators, the NF-A12x25 has been carefully fine-tuned for optimal on-application acoustics. It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (SPL) when working against back pressure.
Flow Acceleration Channels

Flow Acceleration Channels

The NF-A12x25 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.
Ultra-tight tip clearance

Ultra-tight tip clearance

The NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.
Metal-reinforced motor hub

Metal-reinforced motor hub

The centrepiece of the NF-A12x25’s motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination, both measures ensure ultimate precision and increased stability in the critical hub area.
Sterrox® liquid-crystal polymer compound

Sterrox® liquid-crystal polymer compound

The NF-A12x25’s impeller is made from Noctua’s novel Sterrox® liquid-crystal polymer (LCP) compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics that are ideal for reducing resonance and vibration phenomena in advanced fan-blade designs.
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 screws and other mounting systems.
Anti-vibration gasket for watercooling radiators

Anti-vibration gasket for watercooling radiators

The NF-A12x25 includes a silicone gasket that can be used when installing the fan on watercooling radiators or other applications that benefit from a tighter seal with the fan. The gasket helps to damp minute vibrations and to reduce air loss between the fan and the radiator for optimal cooling performance.
SSO2 bearing

SSO2 bearing

The NF-A12x25 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.
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 NF-A12x25 sports 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 fan uses 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.
Smooth Commutation Drive 2

Smooth Commutation Drive 2

The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the fan remarkably quiet even at very close distances.
Low-Noise Adaptor

Low-Noise Adaptor

The NF-A12x25 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 2000 to 1700rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1700rpm 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 fan to the same PWM fan header for automatic control.
Optional adaptor for 140mm watercooling radiators

Optional adaptor for 140mm watercooling radiators

Thanks to its superior efficiency, the NF-A12x25 can outperform many 140mm fans. Combined with the optional NA-FMA1 adaptor frame that allows it to be installed on 140mm radiators, the NF-A12x25 is a great upgrade for 140mm-based watercoolers.
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-A12x25 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer’s warranty.

NF-A12x25 PWM Review

Four and a half years of investment into research and development, for any product, would almost certainly yield impressive results, but when all of that effort is focussed onto one fan, available in one colour and one size, the results are amazing. Our testing showed this fan blows everything else out of the water, including the Corsair ML-120, a fan known for its excellent performance. The construction of the fan is “no compromise” in every single way, going to unbelievable lengths to ensure optimal performance and minimal noise in the process. The fan is easily the heaviest we’ve encountered, tipping the scales at a mighty 201g. A Corsair ML Series 120mm fan, for example, weighs 148g. Noctua believe in their product so much, they tag it with a 6-year warranty; not shabby at all! To round up, if you’re after the best performance or silent operation, this is the only fan we can recommend, full stop. Yeah, it’s pricey at £26, but that is absolutely warranted in our opinion.
Test verdict: "Noctua’s design team have definitely earned their bonus this year; the NF-A12x25 is incredible in every way" (Matthew Hodgson, Vortez.net)

NF-A12x25 PWM Review

Uns hat der fast spaltlose Lüfter überzeugt: Die etwas bessere Kühlleistung verglichen mit dem NF-F12 bei deutlich geringerer Lautheit machen den neuen NF-A12x25 zur Empfehlung für Silent-Freunde, die Wert auf ein extrem leises System legen und den vergleichsweise hohen Anschaffungspreis nicht scheuen.
Test verdict: "Selten haben wir einen so nahezu lautlosen Lüfter gehört - Noctuas Bemühungen zahlen sich definitiv aus." (Marc Sauter, Golem.de)

NF-A12x25 PWM Review

Il test è stato condotto con un microfono posto a 20 cm di distanza per capire come la nuova struttura influenzasse la rumorosità e sono rimasto veramente colpito da come queste nuove ventole riescano ad avere un flusso d’aria così elevato ed uniforme, ma allo stesso tempo una bassissima rumorosità che si aggira intorno al 25% in meno rispetto le ventole NF-F12 se portate a pari velocità.
Test verdict: "Noctua come al solito non ha deluso le aspettative su questi nuovi prodotti, ed è riuscita a migliorare le sue proposte più performanti, tramite la nuova serie NF-A12x25 con l’utilizzo del nuovo materiale a cristalli liquidi Sterrox® LCP, andando così ad aumentare le prestazioni mantenendo una bassissima rumorosità."

NF-A12x25 PWM Review

The Acoustic performance of the Noctua NF-A12x25 speaks for itself, that's if you can even hear it! You can see all that slaving away by Noctua to fine tune every part of their Noctua NF-A12x25 fan has paid off.
Test verdict: "The Noctua Noctua NF-A12x25 may only be a fan, but I have never seen a fan where so much attention to detail has been made to every aspect of its design, airflow, noise, power consumption, aesthetics, accessories, durability and quality." (Ambrosidou Nat, XtremeSystems.org)

NF-A12x25 PWM Review

Mit einem Blick auf das erreichte Kühlergebnis ist zu erkennen, dass sich der neue NF-A12x25 PWM im guten Mittelfeld des Testfeldes platziert hat. Der NF-A12x25 PWM ist seitens Noctua als Allroundtalent entwickelt worden, wodurch er sich gleichermaßen als Lüfter auf einem Radiator, CPU-Kühler oder als Gehäuselüfter eignen muss. Dies gelingt dem NF-A12x25 aufgrund der PWM-Steuerung sehr gut. Dank dieser ist der Lüfter bei dem Einsatz als Gehäuselüfter unhörbar leise. Nutzt man den Lüfter mit voller Drehzahl, so kann er auch hier nicht nur mit einer ausreichend hohen Kühlleistung punkten, mittels welcher man auch eine übertaktete CPU kühlen kann, sondern auch durch eine vergleichsweise geringen Geräuschkulisse.
Test verdict: "Mit dem NF-A12x25 PWM hat Noctua sein Sortiment um einen 120-mm-PWM-Lüfter erweitert, in dessen Impeller man knapp 5 Jahre Entwicklungszeit gesteckt hat. Diese lange Entwicklungszeit hat sich aus unserer Sicht jedoch gerade im Hinblick auf die geringe Geräuschkulisse voll und ganz gelohnt. Der NF-A12x25 PWM konnte in unserem Test jedoch nicht nur durch eine geringe Geräuschkulisse gepaart mit einer guten Leistung punkten, sondern vor allem durch die sehr hochwertige Verarbeitung sowie einem umfangreichen Lieferumfang."

NF-A12x25 PWM Review

Az évek során megszokhattuk, hogy a Noctua kiváló minőségű hűtési megoldásokat dob piacra. Tőlük nem kell várnunk különféle RGB-s ventilátorokat, vagy méretes vízhűtéseket – bár utóbbi termékvonal a pletykák szerint hamarosan érkezni fog – , hanem inkább abban jeleskednek, amiben szerintünk a legjobbak, azaz a ventilátorok terén igyekeznek évről évre maradandót alkotni. A kiváló minőséget a több száz elnyert díj és a pozitív vásárlói visszajelzések is bizonyítják. Persze a minőséget (és természetesen a kutatási költséget) meg kell fizetni… Mai tesztünkben két új ventilátorral ismerkedhettek meg, valamint elhoztunk nektek egy érdekes kiegészítőt, mellyel a Noctua a vízhűtés szerelmesei számára kínál egyfajta alternatívát.
Test verdict: "A Noctua NF-A12x25 ventilátorra úgy gondolom megérte a több, mint négy év várakozás, hisz egy nagyon jó hűtő sült ki a hosszadalmas fejlesztési folyamat eredményeképp. A PWM, FLX és ULN modellek alacsony zajszintűknek és magas hűtési teljesítményüknek köszönhetően használhatók rendszerhűtőként, léghűtéses hűtőbordákhoz és radiátorokhoz egyaránt."

Information Sheet (PDF)

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 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:

  • 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.

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.

Please contact your network device manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and 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.

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!

D15S

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.

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:

pin configuration

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).
