10. CPU, chassis, and power fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN, 3-pin CHA_FAN2, 3-pin PWR_FAN)
The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.)
or a total of 1 A ~ 7 A (84 W 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!
