Fan Power Connector: CPU_FAN1

The fan power connector supports system cooling fan with +12V. When

connecting 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 advantage of the CPU fan control.
