Installation

When installing the NF-B9 on a heatsink or radiator, please use the mounting mechanism supplied with your heatsink

or radiator (fan clips, screws, etc.) as described in the respective manual.

When installing the NF-B9 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-B9 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-B9 will run at full speed (unless the mainboard supports voltage based

speed control).

If you’re using multiple NF-B9 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-B9 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-B9 comes with a Low-Noise

Adaptor (NA-RC7) that allows you to reduce the fan speed from 1600 to 1300rpm. You can either use the adaptor to

set the fan to a fixed speed of 1300rpm (if speed control is deactivated) or to cap the maximum speed to 1300rpm

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-B9’s premium grade SSO 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.

Should you encounter any problems with your NF-B9, please don’t hesitate to contact our support team (support@noctua.at).
