    I have a GA-P35-DS4 motherboard and a Zalman 7700 CPU cooler that has ONLY a 3 pin fan connector that goes to a "fanmate" that can manually control the speed of the Zalman CPU fan.
    The motherboard has 4 pins cpu fan connector.
    Can anybody tell me what the fourth pin on the motherboard is for.
    Is it there to control the fan speed, via the inbuilt (BIOS) fan controls, and by not having the fourth pin connected, the fan speed of the CPU fan is controlled by the "fanmate" and NOT the BIOS.
    This is going into a HTPC so, I want to get this right, so fan noise is at a absolute minimum.
