The CPU_FAN1 CPU_FAN2 (processor fan) and SYS_FAN1 (system fan1)
support system cooling fan with +12V. It supports four/three-pin head connector.
When connecting the wire to the connectors, always take 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.
