15) USB Headers (10-1 pin USB2) (optional)

If the USB port connectors on the back panel are inadequate, two USB headers

are available for two additional USB port connectors. Connect the USB headers

to an optional 2-port USB connector set and mount the bracket to an open slot

on your chassis.

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).

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.
