There are seven 3-pin fan connectors in the Mainboard motherboard. Two fans are used
for CPU0 and CPU1; five 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. CPU0_FAN, CPU1_FAN and SysFAN0 support Smart Fan function.
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.
