Route cables through the provided channels and fasten them with cable ties to maintain clear airflow paths. Confirm front-panel connectors are properly attached to the motherboard header before initial power-on and perform a system POST to verify component detection.

Usage recommendations

For reliable thermal performance and quiet operation, combine front intake and rear/top exhaust fans to establish positive airflow. Use appropriately sized CPU coolers and check clearance dimensions for long graphics cards before purchase. Secure cables away from airflow paths and regularly clean dust filters and internal surfaces to maintain cooling efficiency.
