Airflow & Cooling System
Built with airflow as the top priority, the H3 Flow features a full-mesh front panel and optimized internal layout for unrestricted ventilation. It supports up to six fans, including dual 140mm or triple 120mm in the front, and radiators up to 280mm for liquid cooling setups.
