Fan Power Connectors: CFAN1/SFAN1

The CFAN1 (processor fan) and SFAN1 (system fan) support system cooling fan with +12V. They
support three-pin head connector. When 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 on-board, you must
use a specially designed fan with speed sensor to take advantage of the CPU fan control.
