The fan power connector supports system cooling fan with +12V. W hen connecting

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.
