Installation
When installing the NF-A6x25 PWM on a heatsink, radiator or other devices that use a custom mechanism for fan
installation (fan clips, proprietary screws, etc.) please use this mechanism for installation.
When installing the NF-A6x25 PWM as a case fan, you can either use proprietary clip systems (if your case features a
clip system for fan installation) or the supplied mounting screws and silicone anti-vibration mounts. In order to install
the fan using the silicone mounts, please first pull the silicone mounts through the mounting holes of the case. Then
put the fan onto the silicone mounts and pull them through the mounting holes of the fan:
Connection
The NF-A6x25 PWM comes with a 4-pin PWM fan connector for fully automatic speed control via your mainboard’s
4-pin PWM fan headers. Please note that the fan can also be connected to your mainboard’s 3-pin fan headers
though. When connected to 3-pin fan headers, the NF-A6x25 PWM will run at full speed (unless the mainboard
supports voltage based speed control).
If you’re using multiple NF-A6x25 PWM fans, you can use the supplied y-cable (NA-YC1) to connect several fans to
one PWM fan header. This way, your mainboard will set all the connected fans to run at the same speed.

If you need a longer cable, please add the supplied 30cm extension (NA-EC1).
The NF-A6x25 PWM comes with a Low-Noise Adaptor (NA-RC7) that allows you to reduce the fan speed from 3000 to
2100rpm. You can either use the adaptor to set the fan to a fixed speed of 2100rpm (if speed control is deactivated)
or to cap the maximum speed to 2100rpm 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-A6x25 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.
