CPU Fan and System Fan: CPUFAN and SYSFAN

The CPUFAN (CPU fan) and SYSFAN (system fan) run on +12V and maintain
system cooling. When connecting the wire to the connectors, always be
aware that the red wire is the Positive and should be connected to the +12V.
The black wire is Ground and should always be connected to GND.

FAN_MCM is a switch that is used by high-quality fans to monitor the system
temperature and will automatically adjust according to the environment.
