3. HARDWARE SETUP
6) CPU Fan, Power Fan, and Chassis Fan Connectors
(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 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!
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!

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. (The USB connector set is optional and does not come with the
motherboard package.)
