Noctua Black NA-FC1 PWM Fan Controller [PC]

The Noctua NA-FC1 is a compact and super - flexible 4 - pin PWM fan controller. It can work independently for manual speed reduction or cooperate with the motherboard's automatic fan control. By turning the speed control dial, you can manually set the PWM duty cycle from 0 to 100% or lower the cycle from the motherboard to make fans run slower. The orange status LED shows the current dial setting, and the push - button switches it to 'no stop' mode, keeping the fan above 300rpm. With the included 3 - way split cable and power supply adaptor, you can control up to 3 fans at once.

Using the Noctua NA - FC1 is easy. First, connect the fans to the controller using the 3 - way split cable and the power supply adaptor. You can control up to 3 fans simultaneously. To adjust the fan speed, simply turn the speed control dial. You can set the PWM duty cycle manually from 0 to 100% or reduce the cycle supplied by the motherboard to slow down the fans. The orange LED will show you the current setting on the dial. If you don't want the fan to go below 300rpm, press the push button to switch to 'no stop' mode. When it comes to maintenance, keep the controller in a clean and dry place. Avoid getting it wet or exposing it to extreme temperatures. If you notice any issues with the controller, check the connections first. If the problem persists, it might be a good idea to contact customer support.
