Hardware Setup Fan Power Connectors: CPUFAN, SYSFAN1~5 The fan power connectors support system cooling fan with +12V. W hen 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.

that will automatically control the CPU fan speed according to the actual
CPU temperature.
3. SYSFAN1~3 support fan control, too. You may select how percentage of
speed for the SYSFAN1/2/3 in BIOS.
