Fan Power Connectors: CPUFAN,SYSFAN1~4
The fan power connectors support system coolng fan wth +12V. When connectng the
wre to the connectors, always note that the red wre s the postve and should be con-
nected to the +12V; the black wre s Ground and should be connected to GND. If the
manboard has a System Hardware Montor chpset on-board, you must use a specally
desgned fan wth speed sensor to take advantage of the CPU fan control.
