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!

• The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.

• Only the 4-pin CPU fan supports the ASUS FanXpert and Q-Fan 2 feature.
