III. INSTALLATION
5. CPU Cooling Fan Connector (FAN)
This connector supports a 3-pin CPU cooling fan of 500mAMP (6WATT) or
less with a minimum of 3,500RPM. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be Positive, the black
should be Ground, and the yellow wire should be Rotation signal.
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.
