Fan Power Connectors: CPU_F2, SYS_F2
The fan power connectors support 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 on-board, you must use a specially designed fan with speed
sensor to take advantage of the CPU fan control.
