5. CPU and chassis fan connectors (3-pin CPU_FAN, CHA_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!
