III. INSTALLATION
15. 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 on-
board heat sink(s) instead of the expansion slots. Depending on the fan manu-
facturer, the wiring and plug may be different. The red wire should be posi-
tive, while the black should be ground. Connect the fan's plug to the board
taking into consideration the polarity of the this connector.
WARNING: The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heatsinks. Damage may occur to the mother-
board and/or the CPU fan if these pins are incorrectly used. These are not
jumpers, do not place jumper caps over these pins.
