CPU Fan and System Fan: CPUFAN1 and SYSFAN1
The CPUFAN1 (CPU fan) and SYSFAN1 (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.
