Fan Power Connectors: CPUFAN, SYSFAN1
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 con-
nected 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.
