6 . CPU and system fan connectors (4-pin CPU_FAN1/2, 3-pin REAR_FAN1/2, FRNT_FAN1/2)

The fan connectors support cooling fans of 350 mA ~ 740 mA (8.88 W max.) or a total of 2.1 A ~ 4.44 A (53.28 W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector.

Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! Do not place jumper caps on the fan connectors!

7 . USB port connector (10-1 pin USB34)

This connector is for additional USB 2.0 ports. Connect the USB module cable to this connector, then install the module to a slot opening at the back of the system chassis.

Never connect a 1394 cable to the USB connectors. Doing so will damage the motherboard!
