Fan Power Connectors: C_FAN1/S_FAN1
The C_FAN1 (processor fan) and S_FAN1 (system fan) support
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
Monitor chipset on-board, you must use a specially designed fan with speed
sensor to take advantage of the CPU fan control.
Note:
1. Always consult the vendor for proper CPU cooling fan.
2. CPU Fan supports the fan control. You can install the PC Alert
utility that will automatically control the CPU Fan speed according
to the actual CPU temperature.
