CPU and Chassis Fan Connectors (CPUFAN1/CASFAN1)
The mainboard provides two onboard 12V cooling fan power connectors to
support CPU (CPUFAN1) and Chassis (CASFAN1) cooling fans.
Note: Both cable wiring and type of plug may vary, which depend on the
fan maker. Keep in mind that the red wire should always be con-
nected to the +12V header and the black wire to the ground (GND)
header.
