The Arctic Liquid Freezer III Pro 420 A-RGB (White) is a premium 420mm all-in-one liquid CPU cooler designed for maximum thermal performance. Featuring a thick 38mm aluminum radiator that holds more coolant than standard 27mm designs, it efficiently handles temperature spikes and high TDP loads over 268W.
Key highlights include an integrated PWM-controlled VRM fan (400-2500 RPM) for motherboard cooling, offset cold plate mounting optimized for Intel and AMD CPUs, and pre-installed 3x P14 Pro A-RGB fans with fluid dynamic bearings delivering 110 CFM airflow and 5.2 mmH2O static pressure. The design incorporates built-in cable management, MX-6 thermal paste (0.8g), and flexible control options via splitter cable for independent or synchronized PWM operation.
Compatible with Intel LGA1851/LGA1700 and AMD AM4/AM5 sockets, it includes an Intel contact frame to prevent CPU bending and ensure optimal pressure distribution. Easy installation with pre-connected fans and comprehensive 6-year warranty.
