Description
ARCTIC Liquid Freezer III Pro 420 A-RGB White is a premium liquid cooling system that combines maximum performance with an elegant white design. It is engineered to cool the most powerful CPUs and is ideal for users who value a balance between efficiency, quiet operation, and unique system aesthetics.
Large radiator for extreme workloads
A triple-section aluminum radiator measuring 458x138x38 mm provides a massive heat dissipation surface. Thanks to thick fins and dense ribs, it efficiently dissipates heat even during rendering, 3D modeling, streaming, or running demanding applications. This thermal headroom ensures stable system performance under prolonged full CPU load.
High-performance fans with ARGB lighting
Three 140 mm high-static-pressure fans deliver airflow up to 110 ft³/min and operate within a 400–2500 RPM speed range. They effectively cool even dense radiator fins, balancing performance and noise. All fans feature ARGB lighting, enabling synchronization with other components and customizable lighting effects to match your build.
Smart pump and additional VRM cooling
The modern pump with PWM control automatically adjusts its speed based on thermal load, reducing noise and optimizing power consumption. A dedicated 60 mm fan for the motherboard's VRM area ensures stable CPU power delivery during overclocking or extended work sessions.
Compatibility and easy installation
The system supports popular platforms including Intel LGA1700, LGA1851, and AMD AM4, AM5. It includes a contact frame for Intel CPUs that evenly distributes pressure and prevents CPU deformation. For AMD, an offset cold plate optimizes cooling for Ryzen chiplet hotspots. Fan cables are integrated into the hose sleeves, greatly simplifying installation—only one connector is needed for the entire system.
Durability and reliability
The 2.358 kg system weight reflects the use of high-quality materials and a robust build. The closed-loop design requires no maintenance, with a lifespan designed for years of reliable operation.
The perfect choice for premium builds
The Liquid Freezer III Pro 420 A-RGB White combines top-tier cooling performance, modern features, and striking visual style. It's the ideal solution for enthusiasts and professionals who want to fully unlock their PC's potential and add a unique touch with its white design and customizable lighting.
