The ASUS ProArt LC 420 is an all-in-one liquid CPU cooler designed for high thermal dissipation in content creation and professional workloads. It integrates a 420mm aluminum radiator with three 140mm Noctua NF-A14 industrialPPC-2000 fans to manage heat from high-performance processors. A key feature is the illuminated system status meter on the pump housing, which provides real-time data on select system metrics. The unit's black finish and minimalist aesthetic are specified to align with other components in the ProArt series.
The cooler's thermal performance is driven by the Noctua fans, which operate between 800 and 2000 RPM and are managed via PWM control to balance airflow with acoustics. These fans produce a maximum airflow of 107 CFM and a static pressure of 4.18 mmH2O, intended to move air effectively through the radiator fins. The system is compatible with current Intel and AMD sockets, including LGA 1700 and AM5. Installation is accommodated by 450 mm sleeved rubber tubes, offering routing flexibility within a computer case.
