Hardware Setup Fan Power Connectors: CPUFAN1, SYSFAN1~4 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.
