ASUS A8S-X SE 1-25
5. CPU and chassis fan connectors (3-pin CPU_FAN, CHA_
FAN, PWR_FAN)
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.
The USB/GAME module is purchased separately.
