Never connect a USB cable to the IEEE 1394a connector. Doing so will damage
the motherboard!
You can connect the 1394 cable to ASUS Q-Connector (1394, red) first, and
then install the Q-Connector (1394) to the 1394 connector onboard.

These connectors are for temperature monitoring. Connect the thermal
sensor cables to these connectors and place the other ends to the devices.
The OPT_TEMP1/2/3 connectors are for the devices that you want to monitor
temperature. The optional fans can work with the temperature sensors for a
better cooling effect.
