5. USB connector (10-1 pin USB78)
These connectors are for USB 2.0 ports. You can connect a USB/GAME
module cable to the connectors, then install the module to a slot opening at
the back of the system chassis. These USB connectors comply with USB 2.0
specification that supports up to 480 Mbps connection speed.
4. CPU Fan connectors (3-pin CPU_FAN)
The fan connectors support cooling fans of 350 mA~740 mA (8.88 W max.)
or a total of 1 A~2.22 A (26.64 W max.) at +12V. Connect the fan cables to
the fan connectors on the motherboard, ensuring 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!
