Noctua NA-FC1 Fan Controller
Noctua NA-FC1 Fan Controller
The controller needs 4 pins to control the PWM signal for the fan. Only fans with 4-pin cables allow the speed to be adjusted, fans with 3-pin cables have a fixed speed.
So the cable connecting the controller to the fans must always be 4-pin, or the controller makes no sense. The power supply to the controller can be achieved with an adapter which taps the power at the PSU or other power source.
