Question about Noctua NA-FC1 Fan Controller
Can I also connect a 3 pin plug?
Helpful answer
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.
Use the part to turn down the fan in the RaspberryPie with a 2 PIN connection.
Yes, this should work without any problems.
