3. HARDWARE SETUP
7) CPU Fan, Power Fan, and Chassis Fan Connectors
(CPU_FAN, CPU_FAN2, PWR_FAN, CHA_FAN)
The four 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 sinks instead of the expansion slots. The fan wiring and plug may vary
depending on the fan manufacturer. Connect the fan cable to the connector making
sure that the black wire matches the ground pin. (NOTE: Use the "Rotation"
signal only with a specially designed fan with a rotation signal. You can monitor
the Rotations Per Minute (RPM) 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.

8) USB Header (10-1 pin USBPORT)
If the USB port connectors on the back panel are inadequate, one USB header is
available for two additional USB port connectors. Connect the USB header to a
2-port USB connector set and mount the bracket to an open slot in the chassis.
(The USB connector set is optional and does not come with the motherboard
package.)
