ASUS V-Series P7H55E
3. CPU, chassis and power fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2)
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, 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!
Only the 4-pin CPU fan connector supports the ASUS Q-Fan feature.
