Q & A
Some motherboard’s 4pin fan header actually do not provide PWM signal control and may only provide the same functionality as a 3pin fan header. So if you were unable to control fan speed (with all fan running only at full speed), please connect to 4pin fan header labeled or designated as for CPU fan. In addition, please make sure that all fans you have are also PWM capable.
