The ARCTIC Liquid Freezer III Pro 420 is a high-performance all-in-one liquid CPU cooler designed for demanding desktop builds and workstations. It features a wide 420 mm radiator paired with three 140 mm ARCTIC P14 Pro fans, each capable of reaching up to 2500 RPM and delivering 110 CFM airflow for strong heat dissipation under sustained load.
Built around a PWM-controlled pump and a 38 mm thick radiator, this cooler focuses on quiet operation without sacrificing thermal headroom. The integrated VRM cooling fan helps reduce voltage regulator temperatures, improving overall system stability during heavy workloads or overclocking sessions. ARCTIC also includes a dedicated contact frame for Intel LGA1851 and LGA1700 sockets, distributing mounting pressure more evenly to protect the CPU while enhancing thermal transfer. Native offset mounting for both Intel and AMD platforms shifts the cold plate toward the CPU hotspot for more efficient cooling.
