Nettet7. des. 2024 · The HUBs normally get the fan power through a SATA or Molex power connector and then let the mobo control all the fans like they would be just one using a 4-pin PWM connector. You'll also only get the RPM readout from 1 fan. NettetAnswer (1 of 3): If I needed to control a fan without the special connector, I would setup a PID loop on the CPU temperature and control the fan speed’s power line with a PWM.
