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!
7. Internal audio connectors (4-pin AUX1, CD1)

6. CPU and Chassis Fan Connectors
(3-pin CPU_FAN1, CHA_FAN1)
The two fan connectors support cooling fans of 350mA (4.2 Watts) or
a total of 1A (12W) at +12V. Orient the fans so that the heat sink fins
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.
