2.3.3Installing the optional fans

Install the optional fan only if you are using a passive cooler or a water cooler. Installing the optional fan with an active CPU cooler will interfere with the airflow and destabilize the system.

1.Position the fan above the pipe and heatsink assembly.

3.Carefully push down the fan until it snugly fits the heatsink, then connect the fan cable.

2.Fit the fan to the grooved edge of the heatsink.

4.The photo shows the fan installed on the motherboard.

• Plug the optional fan cable to the CHA_FAN1/2 connector on the motherboard.

Make sure the optional fan is installed correctly to prevent damage to the fan and motherboard components.
