The ARCTIC Liquid Freezer III 420 ARGB is an all-in-one liquid cooling solution designed for high-performance processors. It utilizes a 420 mm aluminum radiator paired with three 140 mm fans to facilitate efficient heat dissipation under sustained loads. The pump assembly includes an integrated fan that directs airflow to the motherboard's voltage regulator modules (VRMs) for enhanced system stability. A copper cold plate ensures direct contact and effective thermal transfer from the CPU heat spreader, maintaining optimal operating temperatures.
The system's three fans and pump are PWM-controlled, allowing for precise speed adjustments based on thermal demand, and connect via a single header for simplified cable management. Addressable RGB lighting on the fans offers customizable illumination, managed through a standard 3-pin connector compatible with most motherboard software. This cooler is built for current Intel and AMD platforms, including LGA 1700/1851 and AM5/AM4 sockets. The unit is supplied with all necessary mounting hardware and features 450 mm rubber tubing for installation flexibility in larger chassis.
