3. HARDWARE SETUP
6) CPU Fan, Power Supply Fan, and Chassis Fan Connectors
(3-pin CPU_FAN/PWR_FAN/CHA_FAN)
The three fan connectors support cooling fans of 350mA (4.2 Watts) or less.
Orient the fans so that the heat sink fins allow airflow to go across the onboard
heat sink(s) instead of the expansion slots. The fan wiring and plug may vary
depending on the fan manufacturer. The red wire should be positive while the
black should be ground. Connect the fan plug to the board taking into
consideration the polarity of the connector.
NOTE: Use the "Rotation" signal only with a specially designed fan with a rotation
signal. The Rotations Per Minute (RPM) can be monitored using ASUS PC Probe
(see 6. SOFTWARE REFERENCE).
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.
