Plug the CPU cooling fan cable into the 3-pin CPU FAN power supply on the
mainboard. Connect the case cooling fan connector to FAN1.

3. CPU FAN & FAN1

4. Front Audio Connector

The audio interface provides two kinds of audio output choices: the Front Audio,
the Rear Audio. Their priority is sequenced from high to low (Front Audio to Rear
Audio). If headphones are plugged into the front panel of the chassis (using the
Front Audio), then the Line-out (Rear Audio) on the rear panel will not work. If you
do not want to use the Front Audio, pin 5 and 6, pin 9 and 10 must be SHORT, and
then the signal will be sent to the rear audio port.
