Arctic Liquid Freezer III Pro 420 A-RGB Black (ACFRE00185A)

The Arctic Liquid Freezer III Pro 420 A-RGB is an AIO-class liquid cooling system for CPUs with a 420 mm radiator, designed for high-performance platforms. The system comes equipped with three P14 Pro 140 mm fans operating at 400–2500 RPM, delivering up to 110 CFM of airflow with a static pressure of 5.2 mm H₂O. The pump operates in the range of 800–2800 RPM under PWM control. It is compatible with Intel LGA1851/LGA1700 and AMD AM5/AM4 sockets, featuring a copper base plate with microstructures and an aluminum radiator measuring 458 × 138 × 38 mm. The 500 mm hoses provide additional flexibility when building in larger chassis. An integrated VRM fan running at 400–2500 RPM, offset mounting for improved contact at the CPU heat hotspot, and a built-in contact frame for Intel help optimize cooling performance. Cable routing is hidden within braiding, reducing the number of loose wires near the socket. The system weighs approximately 2370 g and is designed for stationary high-performance builds with proper 420 mm radiator support in the chassis, delivering maximum cooling capacity without requiring a custom loop.
