ARCTIC Liquid Freezer III 420 Pro A-RGB White
ARCTIC Liquid Freezer III 420 Pro A-RGB White
The Arctic Liquid Freezer III 420 Pro A-RGB water cooler in white dissipates heat from high-performance Intel and AMD processors. This 420mm AIO CPU cooler uses a massive radiator fitted with three P14 Pro A-RGB fans, which operate in the range of 400 to 2500 RPM. The system supports modern sockets including Intel LGA1851 and AMD AM5. The water block includes an integrated fan for VRM cooling and an innovative mounting system that improves contact with the processor's heat spreader and optimises heat dissipation.
Key features of the Arctic Liquid Freezer III 420 Pro A-RGB water cooler, white
- Integrated fan actively cools the power stage components
- Thicker radiator increases the cooling surface and liquid volume
- Special contact frame improves contact with Intel processors
- Offset mounting optimises cooling for AMD and Intel processors
- Fan cables integrated into the hose sleeving keep the installation tidy
- System offers a choice between unified and separate speed control
Optimised heat transfer
For Intel processors, the cooler uses a special contact frame that distributes pressure evenly and prevents deformation of the CPU and socket. For AMD and Intel processors, it uses an offset mount for better coverage of the chiplets. This solution concentrates the cooling power directly on the hotter spots of the processor, leading to a more effective temperature reduction. Heat transfer is further enhanced by the included MX-6 thermal paste.
Power stage and radiator cooling
Located directly in the pump block is a small PWM fan that provides targeted airflow to the power stage on the motherboard. This element actively reduces the temperature of key components, which contributes to system stability under heavy load. The cooler uses a 38mm thick radiator. The greater thickness increases the volume of the coolant and expands the total surface area for heat dissipation.
Simple installation of the Arctic water cooler
The manufacturer has daisy-chained the fans and hidden their cables in the hose sleeving. This solution significantly simplifies wiring and keeps the inside of the case tidy. The system offers two options for controlling the fan speed. You can either control all components—the pump, VRM fan, and radiator fans—with a single PWM signal, or you can split them up and regulate each part separately.
