CPU/ System Fan Connectors
There are five 3-pin fan connectors in the Mainboard. Two fans are
used for CPU1 and CPU2; three fans are for system and front. These
connectors support cooling fans of 500mA (6W) or less. Depending on
the fan manufacturer, the wiring and plug may be different. Connect the
fan’s plug to the Mainboard with respect to the polarity of the fan
connector.
WARNING
The CPU and/or motherboard will overheat if there is not enough
airflow across the CPU and onboard heatsink. 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.
