About this product
The Arctic Liquid Freezer III Pro 420 A‑RGB (Black) is a 420 mm all‑in‑one CPU liquid cooler intended for users building high‑performance desktop systems. It features a thick 38 mm radiator, three ARCTIC P14 Pro A‑RGB 140 mm fans, and a PWM‑controlled pump with integrated VRM fan — making it a solid choice for overclockers and small form factor PC enthusiasts.
This cooler supports both current Intel and AMD mainstream sockets, including LGA1851, LGA1700, AM5, and AM4, so it works with a wide range of CPUs. Its addressable RGB lighting, including Gen2 LEDs on the fans and pump block, offers customizable aesthetics with daisy‑chain support.
Before buying, check that your PC case can accommodate a 420 mm radiator and that motherboard fan headers (either one 4‑pin PWM or three separate) are available for full control. Also ensure there is clearance around M.2 slots — Arctic provides an M.2 cooler if needed.
