    1. Power the system on and tap "Delete" to enter the BIOS.
    2. Click Hardware Monitor.
    3. Select the system header fan showing an RPM that is not 0. This controls the case fans.
    4. Switch it to PWM. Fans speed should change immediately.
    5. F10 to save and exit.

    We'll be posting BIOS E7D25IZ1.1M9 shortly on the PowerSpec forum. It is a customized version of 7D25v1A. It will resolve the issue of the board sometimes not properly detecting the PWM wire from the fan controller.
