Hardware Setup
Fan Power Connectors: CFAN1/SFAN1
The CFAN1 (processor fan) and SFAN1 (system fan) support system
cooling fan with +12V. It supports three-pin head connector. When connect-
ing the wire to the connectors, always take note that the red wire is the posi-
tive 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.
