7) 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 such that it blows air 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: The “Rotation” signal should be used
accordingly for a specially designed fan with a rotation signal. You can monitor the
Rotations Per Minute (RPM) using ASUS PC Probe (see 6. SOFTWARE
REFERENCE).
8) 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!
