9. CPU and chassis fan connectors (3-pin CPU_FAN, CHA_FAN)
The fan connectors support the proprietary CPU fan and chassis fan.

ground pin.
Do not forget to connect the fan cables to the fan connectors. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
