6) CPU Fan and Chassis Fan Connectors

(CPU1_FAN, CPU2_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 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).

7) USB Headers (10-1 pin USB2_3, USB4_5)

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

available for four additional USB port connectors. Connect a 2-port USB connector

set to a USB header and mount the USB bracket to an open slot in the chassis.

WARNING! Make sure to connect the fan cables to the fan connectors. Lack of

sufficient airflow within the system could cause damage to the motherboard.

These are not jumpers, do not place jumper caps over these connectors!
