The ARCTIC Liquid Freezer III Pro 420 A-RGB (White) – Multi Compatible All-in-One CPU Water Cooler with A-RGB delivers premium liquid cooling for demanding PC builds.

Key Specifications

Triple-Fan Performance for Maximum Cooling

The Liquid Freezer III Pro 420 features three 140mm fans operating at 400-2500 RPM, delivering up to 110 CFM of airflow across the large radiator surface. This high-volume air movement efficiently dissipates heat from both the CPU and VRM components, making it ideal for overclocking and sustained heavy workloads. The Fluid Dynamic Bearing fans ensure quiet operation even at maximum speed.

Universal Socket Compatibility

Supporting the latest Intel LGA 1700 and 1851 sockets alongside AMD AM4 and AM5 platforms, this cooler offers broad compatibility across current-generation CPUs. The multi-compatible mounting system simplifies installation whether you’re running a high-core-count Intel processor or AMD’s latest Ryzen chips, ensuring your investment remains relevant through multiple platform upgrades.

Premium ARGB Lighting Effects

The ARGB lighting system provides vibrant, customizable illumination with 3-pin + 3-pin LED connectors for synchronised effects. The white radiator and pump housing create a clean canvas for the multi-colour lighting, allowing you to match your build’s aesthetic theme. Control the lighting through compatible motherboard software or ARCTIC’s own controller for coordinated system lighting.

Maintenance-Free Operation

As a sealed all-in-one solution, the Liquid Freezer III Pro 420 requires no maintenance, filling, or tube routing. The copper base plate ensures efficient heat transfer from the CPU, while the aluminum radiator provides excellent heat dissipation. With a 50cm tube length, installation flexibility is maintained even in larger cases.
