Fan Power Connectors: CPU_FAN1,
SYS_FAN1
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.
