Efficient AIO cooling: The ARCTIC Freezer III Pro 420 A-RGB is an all-in-one CPU liquid cooler designed to deliver strong thermal performance for demanding systems.

420 mm radiator: Large radiator size helps improve heat dissipation for better cooling capacity under load.

A-RGB lighting: Adds dynamic lighting effects to complement gaming and performance PC builds.

Broad socket compatibility: Supports Intel LGA1700 and LGA1851, as well as AMD AM4 and AM5 platforms.

6000 RPM pump: High pump speed helps maintain effective coolant circulation for reliable thermal control.

Premium radiator design: The 38 mm radiator holds more liquid than conventional 27 mm radiators to reduce heat buildup and handle temperature spikes more efficiently.

Optimized mounting: Native offset mounting for Intel and AMD helps improve heat transfer by shifting the cold plate toward the CPU hotspot.

Enhanced fan performance: Equipped with ARCTIC Pro series fans engineered for stronger airflow, better cooling performance, and quieter operation at lower speeds.

Radiator material: Aluminum radiator construction.
