Fan Power Connector: CPU_FAN1~2, SYS_FAN1~3

The fan power connectors support system cooling fan with +12V. When con- necting the wire to the connectors, always note that the red wire is the positive and should be connected to the +12V; the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset onboard, you must use a specially designed fan with speed sensor to take advan- tage of the CPU fan control.
