13) CPU/Power/Chassis Fan Connectors (3-pin CPU_FAN1,
PWR_FAN1, CHA_FAN1)
Three fan connectors support cooling fans of 350mA (4.2 Watts) or less.
Orient the fans so that airflow flows across the onboard heat sinks instead of
expansion slots. The fan wiring and plug vary depending on the type
employed. Connect the fan cable to the connector, ensuring that the black
wire matches the ground pin. (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 5. SOFTWARE SUPPORT).

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!
14) IEEE-1394 Header (8-pin 1394HEAD) (Optional)
This header supports an IEEE-1394 serial connector cable set that mounts
to a standard expansion slot in the computer case. 1394-compliant internal
fixed disk drives may also be connected to these headers.
