About this product
The ARCTIC Liquid Freezer III Pro 420 A-RGB in white (ACFRE00189A) is a flagship 420mm all-in-one liquid cooler, built for the hottest desktop processors. ARCTIC rates it at 420W (PI) and 376W (NNPI), which covers top-end Ryzen and Intel Core chips under sustained full load.
The radiator explains its strength. At 458 × 138 × 38mm, it is both large and thick: the 38mm aluminium core gives a 23% larger cooling surface than standard 27mm radiators. Three ARCTIC P14 Pro A-RGB 140mm fans push air through it at 400–2500 RPM, with up to 110 CFM of airflow and 5.2 mmH₂O of static pressure, needed to drive air through a dense, thick radiator. The fans use fluid dynamic bearings for quiet running and long life.
The pump runs at 800–2800 RPM under PWM control, over a copper cold plate with micro skived fins for efficient heat transfer. ARCTIC also builds a VRM fan into the pump head, spinning at 400–2500 RPM, which cools the motherboard's power delivery around the socket, an area liquid coolers usually leave without airflow.
Lighting comes from 12 A-RGB Gen2 LEDs per fan plus the pump block, connected through a 3-pin A-RGB plug with daisy-chain support. ARCTIC MX-6 thermal paste comes pre-applied. Tubes are 500mm long.
Socket support covers Intel LGA1851 and LGA1700 and AMD AM5 and AM4.
Your case must support a 420mm radiator with a 38mm thick core plus fans; many mid towers do not, so check before you order.
Who it suits: enthusiasts building white, high-end PCs who want maximum cooling. ARCTIC covers it with a 6 Years warranty.
