8. CPU Cooling Fan Connector (FAN)
This connector supports a CPU cooling fan of 500mAMP (6WATT) or less.
Orientate the fan so that the heat sink fins allow airflow to go across the onboard
heat sink(s) instead of the expansion slots. Depending on the fan manufacturer,
the wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan's plug to the board taking into consid-
eration the polarity of the this connector.
WARNING: The CPU and/or motherboard will overheat if there is no air-
flow across the CPU and onboard heatsinks. Damage may occur to the
motherboard and/or the CPU fan if these pins are incorrectly used. These
are not jumpers, do not place jumper caps over these pins.
