NF-P12 Review

Hinsichtlich seines Geräuschbildes hebt sich der verbaute NF-P12 durchaus von seinen günstigeren Kontrahenten ab. Bei maximalen 1300 U/min sind leichte Luftumschlagsgeräusche zu vernehmen, die subjektiv etwas weicher ausfallen. Ab 7 Volt abwärts gibt der unorthodox gefärbte Ventilator absolut keinen Mucks mehr von sich. Entscheidend dabei: Nervige Nebengeräusche wie Rotorschleifen, -Rasseln oder -Klackern, wie wir sie häufig beobachten müssen, scheinen dem NF-P12 vollkommen fremd.
Test verdict: "Über die Vergabe unserer Redaktionsempfehlung für den NH-U12P, aber auch für den NF-P12 als Einzellüfter, muss überdies nicht weiter diskutiert werden." (Martin Eckardt, Computerbase.de)

NF-P12 Review

It beat out all of the other fans we put it up against even though the gap narrowed a bit in the last water cooling test. This shows that the high degree of engineering put into this product was not just window dressing since it performs exactly as Noctua promises and then some. Whether it was cooling a Thermalright heatsink or a Black Ice radiator, the NF-P12 proved that it was the best choice for applications which call for a high amount of static pressure. Without a doubt, every part of Noctua’s fan is top notch in terms of build quality and performance. I also like the fact that all of the mounting hardware is included and as well as two prepackaged adaptors for lowering the rotational speed of the fan. What really surprised me was the distinct lack of noise produced by this Noctua fan. I was prepared for a moderate increase in noise over the NF-S12 fans I was using on my case but lo and behold, the NF-P12 equaled the quiet performance of Noctua’s older fans. To have this kind of performance with the lack of blade or motor noise is a dream come true for people who demand the quietest PC possible. In many cases, an enthusiast will buy a fan speed controller or build their own resistors into a fan’s wiring in order to lower the amount of noise produced by a fan. With the NF-P12 that is no longer necessary since not only does it offer near-silent operation but Noctua has also included two fan speed adaptors to lower RPMs for even less noise.
Test verdict: "Personally, I think that the tests in this review speak louder than any conclusion I can write because the results were so convincing. The Noctua NF-P12 was the best fan we tested. Period." (SKYMTL, HardwareCanucks.com)

NF-P12 Review

Utilising both the NF-S12 and NF-P12 120mm fans on the radiator for our cooling tests yielded some interesting results. I have included some Scythe S-FLEX results in the chart to help make a comparison. The NF-S12 800 gets left behind at 7v, but the NF-P12 performs better than the Scythe S-FLEX's thanks to its increased static pressure. The NF-P12 certainly has the goods and it performs well whilst being almost totally quiet. Excellent effort Noctua!
Test verdict: "I have absolutely no hesitation in recommending the Noctua NF-P12 120mm cooling fans as a worthy addition to your cooling system." (Matthew Fogg, Overclock3D.net)

NF-P12 Review

The first thing you'll notice with the Noctua NF-P12 fan is the lack of noise at all rpm levels. The next thing you'll see in the testing results is that the Noctua fan performs better than the other fans while running at a lower fan speed. Obviously the design of the Noctua is excellent, allowing better performance at a lower fan speed while maintaining virtually no noise. Essentially what we are seeing here is that the Noctua NF-P12 is more efficient at moving air than the other fans tested, something that is very desirable with any type of fan.
Test verdict: "Noctua performs better than the other fans used in the comparison while running at lower speeds. Silence, performance and quality are things that have become synonymous with Noctua, they truly do make some of the best performing fans on the market today." (Kristofer Brozio, DragonSteelMods.com)

NF-P12 Review

As decibelmeters don't tell everything I also did some more subjective noise tests. I listened to the noise of both fans to judge which one makes the least noise but this wasn't an easy task as both fans are very quiet. At a distance of more than a meter you practically won't be able to hear them unless your room is very quiet. The noise production of both fans seems to be about even but I have to admit that the psychoacoustic optimizations seem to work as when I put the fans right next to my ear I found the noise produced by the NF-P12 a bit more pleasant.
Test verdict: "Once again Noctua doesn't disappoint. The NF-P12 produces a decent airflow, a high static pressure and is extremely quiet. This fan is perfect for low-noise CPU, radiator, PSU or case cooling." (Thomas De Maesschalck, DVhardware.net)

NF-P12 Review

It's incredible the volume that this fan produces and equally incredible when you see not only the airflow figures but the static pressures. It obvious that this fan has been designed for watercooling setups where static pressure plays a large role.
Test verdict: "Quite simply put, the Noctua NF-P12 is THE quietest wind maker I’ve ever seen." (Steve Parker, XSReviews.co.uk)

NF-P12 Review

Nous avons passé en revue les 20 modeles les plus courants, achetes en boutique et sur 5 sites Internet Vu la frequence de rotation plus Faible de ces modeles, nous avons choisi des tensions de 12/ 10/7 volts au lieu de 12/7/5 volts comme sur les 80 mm. Comme nous allons le voir, les ecarts sont nettement plus importants...
Test verdict: "[L]es ventilateurs de 120 mm justifient souvent le prix plus eleve demande par les fabricants haut de gamme. [...] Pour ceux qui veulent le silence quoi qu'il arrive, le Noctua NF-P12 (18 euros) remplit parfaitement son role, tout en maintenant une bonne efficacite."

NF-P12 Review

Noctua NF-P12 Bot die mit beste Leistung im Test, knapp vor seinem Markengefährten S12B und dem Cougar, aber hinter den drehzahlstärkeren Aerocool und Silverstone. Alle drei waren trotz deutlich geringerer Drehzahl aber minimal besser als der Enermax PWM. Nahezu unhörbar, frei von Nebengeräuschen, selbst der Luftumschlag auf dem Megahalems war kaum wahrnehmbar.
Test verdict: "Ein bewährter Spitzenlüfter, zu dem man auch auf Grund der Flexibilität über die beiliegenden Adapter weiterhin unbedenklich greifen kann. " (Michael Keilholz, Freeocen.de)

NF-P12 Review

The Noctua NF-P12 comes with plenty of accessories for installation/setup and if you watched the video without skipping, in the tests it was fantastic and absolutely silent on both of the lower speed settings (using both low noise adaptors), even when they are running at full speed you’d expect the noise level to rise but the noise level was not very high compared to other various fans I have used. I used five of the Noctua NF-P12 in the BitFenix Shinobi Window chassis and they noise level is just pleasant to my ears, silent indeed.
Test verdict: "For those who are into gaming and have high end components then the Noctua NF-P12 are perfect for giving the best airflow and keeping your pc cool and silent! I would highly recommend the Noctua NF-P12, top notch 120mm fan." (Shay Miah, Shay-Tech.co.uk)

NF-P12 Review

En los test con el Kit Corsair H60 hemos visto que tiene un comportamiento similar al Nidec de 1450 RPM, dando la talla perfectamente. Quizás su estética no sea muy llamativa pero ofrece un excelente rendimiento en todos los campos (silencio, ofimática, overclock...) En resumidas cuentas el Noctua NF-P12 sigue siendo una gran opción en el mercado
Test verdict: "Aunque el NF-P12 lleve casi cuatro años en el mercado, sigue siendo uno de los mejores ventiladores respecto RPM / Caudal de aire / Sonoridad." (Miguel Ángel Navas, ProfesionalReview.com)

Can I use Noctua fans on my fan controller?

Our fans are compatible with the vast majority of fan controllers on the market. However, there is a compatibility issue with a few models such as the Zalman ZM-MFC2 and Bitfenix Recon, which apply Pulse Width Modulation (PWM) on the 12V line and use an unfavourable PWM carrier frequency. This can create an oscillation when used with certain fans, which will result in the fan speeding up and down. We therefore recommend not using the Zalman ZM-MFC2 or Bitfenix Recon with our fans.

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.


The fan doesn’t start with the Ultra-Low-Noise Adaptor (ULNA)!

Unfortunately, many Gigabyte mainboards use a special control circuit that can lead to start-up problems in conjunction with the Ultra-Low-Noise Adaptor (ULNA). This control circuit remains active even when automatic fan control is disabled in the BIOS. In these cases, please use the fan without the ULNA or connect it directly to the power supply (or an external fan controller) in order to ensure reliable operation with the ULNA.

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 (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 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.

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:

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.

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!


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.

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.
