3. HARDWARE SETUP
14) Power Supply, CPU, Chassis Fan Connectors
(3-pin PWR_FAN, CPU_FAN1, CHA_FAN)
These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan's plug to the board taking into consid-
eration the polarity of the connector.
NOTE: The "Rotation" signal is to be used only by a specially designed fan with
rotation signal. The Rotations per Minute (RPM) can be monitored using ASUS PC
Probe (see 6. SOFTWARE REFERENCE) or Intel LDCM Utility.
WARNING!
The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heatsinks. Damage may occur to the motherboard
and/or the CPU fan if these pins are incorrectly used. These are not jumpers,
do not place jumper caps over these pins.

15) Internal Audio Connectors (4-pin CD_IN, AUX, VIDEO, MODEM)
These connectors allow you to receive stereo audio input from such sound sources
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 mono_out (such as a
speaker) between the onboard audio and a voice modem card.
