Fan Power Connectors: CFAN1/SFAN1/NBFAN1
The CFAN1 (processor fan), SFAN1 (system fan) and NBFAN1
(NorthBridge Chipset 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.
MSI Reminds You...
1. Always consult the vendors for proper CPU cooling fan.
2. CFAN1 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.
