Positive Airflow / Mesh Front Panel

A positive pressure airflow configuration uses more intake fan CFM than exhaust fan CFM, creating slight internal over-pressure. This reduces passive dust ingestion through ungasketed gaps compared to negative pressure setups, and ensures fresh ambient air reaches components. High-mesh-density front panels (Fractal Define 7 Perforated, NZXT H7 Flow, Corsair 4000D Airflow) provide low restriction with pre-installed dust filters. Target airflow for a modern gaming system is 50+ CFM net intake. Mesh front and top panels on cases like the Phanteks Eclipse G360A and Lian Li Lancool III support aggressive fan mounting for maximum flow.
