DO NOT forget to connect the fan cables to the fan connectors. Insufcient air ow inside
the system may damage the motherboard components. These are not jumpers! DO NOT
place jumper caps on the fan connectors.
• The CPU_FAN connector supports a CPU fan of maximum 1A (12 W) fan power.
• Only the CPU_FAN and CHA_FAN1/2/3 connectors support the ASUS Fan Xpert
feature.
• If you install two VGA cards, we recommend that you plug the rear chassis fan cable
to the motherboard connector labeled CHA_FAN1/2 for better thermal environment.

3. CPU and chassis fan connectors (4-pin CPU_FAN, and 4-pin CHA_FAN1/2/3)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
2. USB 2.0 connectors (10-1 pin USB910, USB1112, USB1314)
These connectors are for USB 2.0 ports. Connect the USB module cable to any of
these connectors, then install the module to a slot opening at the back of the system
chassis. These USB connectors comply with USB 2.0 specication that supports up to
480Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
The USB 2.0 module is purchased separately.
