4. CPU and chassis fan connectors (3-pin CPU_FAN, CHA_FAN)
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. Connect the fan
cable to the connector matching the black wire to the ground pin.

5. Internal audio connectors (4-pin AUX, CD)
These connectors allow you to receive stereo audio input from sound
sources such as a CD-ROM, TV tuner, or MPEG card.
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!
