    Fan Header Control Setting In BIOS Appears Functionless...


      I have two mostly identical 35W TDP builds based on the DH77DF desktop board.  I am using the system with a large fanless heatsink on the CPU.  The case has two fans which I have upgraded in favor for a variety that has PWM control and the capacity to move a larger volume of air.  I have connected one fan to the CPU fan header and the other to the system fan header.  I, then, adjusted the BIOS setting for both fans to be controlled with the CPU temperature, however the fan on the system fan header never throttles up, only the CPU fan regardless of what I put in the BIOS setting...  MS Windows 7 may at fault...  Would anyone know a way to have the fans control in an identical manner without combining the PWM inputs of the fans to a single header?
