5. CPU, power and chassis fan connectors (3-pin CPU_FAN1, PWR_FAN1,
CHA_FAN1)
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!

6. USB header (10-1 pin USB56, USB78)
If the USB ports on the rear panel are inadequate, a USB header is available
for additional USB ports. Connect the USB cable of the USB 2.0 module to this
header. You may install the USB module in the chassis front panel. The
module has two USB 2.0 ports for connecting next generation USB peripherals
such as high resolution cameras, scanners, and printers.
