The ARCTIC Liquid Freezer III Pro 420 is an all-in-one liquid CPU cooler designed for high thermal loads, featuring a 420mm aluminum radiator and three 140mm P14 Pro fans. The radiator's 38mm thickness increases the cooling surface area for enhanced heat dissipation. An integrated VRM fan is built into the pump housing to direct airflow over the motherboard's voltage regulators, contributing to system stability. All rotating components are PWM-controlled, allowing for precise speed adjustments that balance cooling performance and noise output based on system demand.
This cooler is compatible with Intel LGA1851/LGA1700 and AMD AM4/AM5 sockets. It includes a specific contact frame for Intel processors to ensure uniform mounting pressure and optimal contact with the CPU heat spreader. For AMD systems, an offset mounting mechanism is provided to align the cold plate directly over the processor's core hotspots. The unit can be operated via a single cable for unified control, or components can be managed separately using an included splitter for the pump, radiator fans, and VRM fan.
