The problem is my 3-pin AMD cpu stock fan runs full speed on the ASRock 980DE3/U3S3 I just replaced yesterday which has 4-pin header. It doesn't have the CPU Smart Fan Mode in the bios for me to set the Voltage mode for a 3-pin CPU fan. Neither SpeedFan nor ASRock OC Tuner solves my problem.
I really need your help guys.
