Fan Power Connectors: CFAN1/SFAN1/J7
The CFAN1 (processor fan), J7 (chipset fan) & SFAN1 (system fan) sup-
port system cooling fan with +12V. It supports 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 Moni-
tor chipset on-board, you must use a specially designed fan with speed sensor
to take advantage of the CPU fan control.
