Configure cooling by installing 120mm fans in the front and top positions and optionally a 140mm or 120mm fan at the bottom to promote airflow.

For optimal thermal performance, use a front intake 120mm fan combined with a top exhaust 120mm fan and, if space allows, a bottom 120mm or 140mm intake. Choose low-profile CPU coolers or compact air coolers compatible with the case’s internal clearance, and prefer 2.5" SSDs for the fastest storage response in small builds.
