2.3.3 Installing the optional fan
1. Position the fan above the pipe
and heatsink assembly.
2. Fit the grooved edge to the
heatsink.
3. Carefully push down the fan until
it snugly fits the heatsink, then
connect the fan cables.
4. The above photo shows the fans
installed on the motherboard.
• Plug the optional fan cables to any of the OPT FAN1~5 connectors on the
motherboard.
• Make sure the optional fan is installed correctly to prevent damage to the
fan and motherboard components.
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.
