R_FAN 0 / 1 / 2 / 3, SB_FAN0
The fan power connectors support system cooling fan with +12V. W hen connecting
the wire to the connectors, always take 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 onboard, you must
use a specially designed fan with speed sensor to take advantage of the CPU fan
control.
