Dear customer,

Congratulations on choosing the Noctua NF-A12x25 PWM.

Our fans are renowned for their impeccable quality and outstanding longevity and

like all Noctua fans, the NF-A12x25 PWM features an MTTF rating of more than

150.000 hours that’s backed up with our 6 years manufacturer’s warranty.

Each Noctua fan is double checked for flawless operation by our quality control team

before it leaves the factory and I’m confident that you will be able to sense some of

the research, attention and care we’ve put into making this product.

Enjoy your NF-A12x25 PWM!

Yours sincerely,

Roland Mossig, Noctua CEO

User Manual

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 don’t use a vacuum cleaner as this may apply excessive

force to the fan.

In order to ensure flawless operation over many years of usage, the

NF-A12x25 PWM’s premium grade SSO2 bearing 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.

Warranty and Support

Even with high-grade products and strict quality control, the possibility

of defects cannot be eliminated entirely. Therefore, we aim at providing

the highest possible level of reliability and convenience by offering a war-

ranty period of 6 years and direct, fast and straightforward RMA service.

Should you encounter any problems with your NF-A12x25 PWM, please

don’t hesitate to contact our support team (support@noctua.at).

The NF-A12x25 PWM comes with a 4-pin PWM fan connector for

fully automatic speed control via your motherboard’s 4-pin PWM fan

headers. Please note that the fan can also be connected to 3-pin fan

headers though. When connected to 3-pin fan headers, the NF-A12x25

PWM will run at full speed (unless the motherboard supports voltage

based speed control).

If you’re using multiple NF-A12x25 PWM fans, you can use the sup-

plied y-cable (NA-YC1) to connect several fans to one PWM fan header.

This way, your motherboard will set all the connected fans to run at

the same speed.

The NF-A12x25 PWM features a short 20cm primary cable in order

to help you minimise cable clutter in typical applications. If you need

a longer cable, please add the supplied 30cm extension (NA-EC1).

The NF-A12x25 PWM comes with a Low-Noise Adaptor (NA-RC14) that

allows you to reduce the fan speed from 2000 to 1700rpm. You can

either use the adaptor to set the fan to a fixed speed of 1700rpm

(if speed control is deactivated) or to cap the maximum speed to

1700rpm during PWM speed control.

Connection

The NA-AVG1 gasket can also be used for other applications that

benefit from a tighter seal with the fan.

If you replace an existing 120mm fan with the NF-A12x25 PWM in

other devices, it is generally recommended to fix it with the screws (or

other mounting mechanism) used for the original fan.

When installing the NF-A12x25 PWM as a case fan, you can either

use the supplied mounting screws or NA-AV2 silicone anti-vibration

mounts.

For installing the NF-A12x25 PWM on a CPU heatsink or watercooling

radiator, please use the fan mounting mechanism supplied with said

product (fan clips, screws, etc.).

For optimal cooling performance on watercooling radiators, it is

recommended to change the stock NA-AVP1 anti-vibration pads for

the included NA-AVG1 anti-vibration gasket in order to reduce air loss

between the fan and the radiator:

Installation Cleaning and Maintenance

If you prefer anti-vibration mounts with flat case-side ends, please

purchase the optional NA-AV4 mounts.

For installing the fan using the NA-AV2 mounts, please first pull the F

side through the fan’s mounting holes and then pull the C side through

the mounting holes of the case:

F = fan side C = case side

If the long ends of the mounts are in the way, you can use scissors to

cut them after installation. Note that this will then make them difficult

to reinstall in the future.
