4. CPU, Chassis and Power Fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN, 3-pin PWR_FAN)
The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the
fan cables to the fan connectors on the motherboard, making sure
that the black wire of each cable matches the ground pin of the
connector.
Do not forget to connect the fan cables to the fan connectors.
Insufficient air flow inside the system may damage the motherboard
components. These are not jumpers! Do not place jumper caps on the
fan connectors!
5. Internal audio connectors (4-pin CD)
This connector allows you to receive stereo audio input from sound
sources such as a CD-ROM, TV tuner, or MPEG card.
