Noctua NF-A12x25 PWM - 2000RPM 120mm Quiet Fan Manual

Installation

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:

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 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.

If you prefer anti-vibration mounts with flat case-side ends, please purchase the optional NA-AV4 mounts.

Connection

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 supplied 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.

Cleaning and Maintenance

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