6. CPU and chassis fan connectors (3-pin CPU_FAN1, CHA_FAN1)
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. 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 CD1, AUX1, MODEM)
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM, TV tuner, or MPEG card. The MODEM connector allows
the onboard audio to interface with a voice modem card with a similar
connector. It also allows the sharing of mono_in (such as a phone) and a
mono_out (such as a speaker) between the audio and a voice modem card.
