Fan connectors (3-pin CPUFAN, SYSTEM)
The fan connectors support a CPU fan and a system fan at +12V.
Orient the fans properly to allow air flow to go across the onboard heat
sinks instead of the expansion slots. The fan wiring and plug may vary
depending on the fan manufacturer. Connect the fan cable to the
connector matching the black wire to the ground pin.

CPU and System Fan Connectors
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!
