3. CPU, Power and Chassis fan connectors
(4-pin CPU_FAN, 3-pin PWR_RAN, 3-pin 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. Insufficient
air flow inside the system may damage the motherboard components.
These are not jumpers! DO NOT place jumper caps on the fan
connectors.
