The ARCTIC Liquid Freezer III Pro 420 is an all-in-one liquid CPU cooler engineered for high thermal performance. It combines a 38 mm thick aluminum radiator with three 140 mm P14 Pro fans, configured to generate high static pressure for efficient heat dissipation through the dense fin stack. A key feature is the integrated, PWM-controlled fan on the pump housing, which provides active cooling for the motherboard's voltage regulator modules (VRM). This targeted airflow helps maintain stable system operation, particularly during overclocking or other demanding tasks.
Compatibility is provided for Intel LGA1700 and LGA1851 sockets via an included contact frame, alongside AMD AM5 and AM4 sockets that utilize an offset mounting mechanism for improved thermal transfer. The fans arrive pre-installed on the radiator in a push configuration, and the entire unit connects with a single cable to streamline the installation and cable management process. Addressable RGB lighting on the fans and pump block is managed through a standard 3-pin connector, and the package includes ARCTIC's MX-6 thermal paste for immediate setup.
