Noctua NF-A12x25 PWM chromax.black.swap 12V 2000RPM 120mm Fan

Noctua’s NF-A12X25 series of fans took Noctua almost five years to develop. They are crammed with features which when all added together achieve performance like no other 120mm fan. They even outperform many 140mm fans!

Features

All black version of the award winning NF-A12x25 series
Impressive performance and low noise from 18.8 dB(A)
Manufactured from Sterrox liquid-crystal polymer compound
Ideally suited for any application
Improved SS02 bearings
Six year warranty

Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctua’s flagship model NF-A12x25 has established itself as a true deluxe choice when it comes to premium-quality quiet 120mm fans. Various state-of-the-art technologies and a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox liquid-crystal polymer material, allow it to achieve superb results in all types of usage: Whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators, the NF-A12x25 is a proven winner.

The chromax.black.swap edition combines the NF-A12x25’s signature quiet cooling performance with an attractive black design and a bundle of swappable red, white, blue, green, grey, yellow and black anti-vibration pads that allow the colour-customisation of the fan to match individual build colour schemes. For further customisation, a wide range of accessories such as coloured cables and anti-vibration mounts are available separately. Topped off with Noctua’s trusted premium-grade SSO2 bearing, more than 150,000 hours MTTF and a 6-year manufacturer’s warranty, the NF-A12x25 PWM chromax.black.swap is the perfect choice for all users who value individual, focused build aesthetics just as much as class-leading quality and performance.

Award-winning NF-A12x25 design

First introduced in 2018, the NF-A12x25 has taken the hearts of quiet cooling enthusiasts around the world by storm and reshaped the common perception of what 120mm fans can do. With more than 100 awards and recommendations from the international press, it’s widely considered to be the best 120mm fan on the market.

Swappable anti-vibration pads in 7 colours

The NF-A12x25 PWM chromax.black.swap comes with 4 white, red, blue, green, grey, yellow and black NA-AVP1 anti-vibration pads. By combining the various colours with black or going all-black using the supplied NA-AVG1 anti-vibration gasket, 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.

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.

FAQ

How do I measure fan size?
The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

I received a small cable (resistor) with my fan; what is it for?
The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.
How can I tell which way the air blows through the fan?
Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.
Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?
Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.
