Fan Power Connectors: CPUFA1/SYSFA1
The CPUFA1 (processor fan) and SYSFA1 (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 con-
nected 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 spe-
cially 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. CPUFA1 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.
