7. CPU, Chassis, and Power Fan Connectors
(3-pin CPUFAN1, CPUFAN2, SYSFAN1, SYSFAN2, SYSFAN3)
The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W 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. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
8. USB header (10-1 pin USB2)
If the USB ports on the rear panel are inadequate, a USB header is
available for additional USB ports. The USB header complies with USB
1.1 specification that supports up to 12 Mbps connection speed.
