Arctic Liquid Freezer III Pro 420 A-RGB CPU Cooler - White

Arctic Liquid Freezer III Pro 420 A-RGB - White is a high-end liquid cooler aimed at serious gaming and workstation configurations. The massive 420 mm radiator and three 140 mm fans provide serious thermal capacity for heavily loaded multi-core CPUs. It supports modern sockets AM4, AM5, LGA 1700, and LGA 1851, so you are covered for current and future platforms. The white design with Addressable RGB lighting makes it suitable for builds where appearance is as important as temperatures.

What you get: a massive 420 mm radiator with three 140 mm fans that practically give you a large area for heat exchange and low temperatures even under prolonged full load. The fans operate in the range of 400–2500 RPM, allowing both quiet and aggressive modes depending on the profile you seek. The water block features a copper base for better contact and thermal conductivity to the CPU, while the pump with a speed of 800–2800 RPM reliably moves the liquid through the system. 500 mm hoses give you flexibility in installation in larger cases – you can position the radiator at the front or top without struggling with stretched tubes. Fan and lighting control is through standard 4-pin and 5V ARGB connectors, making it easy to connect to your motherboard and the software you already use.

• A massive radiator with a size of 420 mm, providing a large area for dissipating heat from powerful processors and long sessions under load.
• Three fans with dimensions 140 x 140 x 27 mm, combining high airflow with lower RPM for a more pleasant acoustic profile.
• A wide RPM range of 400–2500 RPM, allowing fine tuning between maximum performance and quiet operation.
• Airflow up to 110 CFM and maximum pressure 5.2 mmH2O, suitable for dense radiator fins and optimal cooling.
• A water block with a copper base for better thermal conductivity and stable heat dissipation from the CPU cap.
• A pump with speeds of 800–2800 RPM and power supply DC 12V, ensuring reliable fluid flow in the system.
• Standard 4 PIN connectors for the fans and 5V Addressable RGB for the lighting, facilitating integration with most modern motherboards.
• 500 mm length of the tubes for flexible installation in larger cases and freer routing of the loop.
• Elegant white design with A-RGB, suitable for light builds and showcases with transparent side panels.

This cooler is suitable if you are looking for serious cooling for high-end CPUs, overclocking, or long render/compilation tasks and have a case that supports a 420 mm radiator. It is ideal for 1440p/4K gaming machines and heavy multitasking, where the CPU spends a lot of time under high load. It is not particularly suitable for small cases or budget systems, where a 240 mm AIO or air cooler would be a more logical choice.

The combination of a 420 mm radiator, three 140 mm fans with high CFM, and a copper water block makes the Arctic Liquid Freezer III Pro 420 A-RGB - White a serious tool for temperature control without sacrificing the aesthetics of your white build.
