Chapter 5: Motherboard Information
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!

CPU and Chassis Fan Connectors
(3-pin CHA_FAN1, CPU_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.
