Installation

When installing the NF-A15 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-A15 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:

If necessary, you can easily remove the NF-A15's integrated anti-vibration pads:

Connection

The NF-A15 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-A15 will run at full speed (unless the mainboard supports voltage based speed control).
If you're using multiple NF-A15 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.
The NF-A15 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-A15 comes with a Low-Noise Adaptor (NA-RC9) that allows you to reduce the fan speed from 1200 to 900rpm. You can either use the adaptor to set the fan to a fixed speed of 900rpm (if speed control is deactivated) or to cap the maximum speed to 900rpm 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-A15'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.
