ARCTIC Liquid Freezer III 420 Pro A-RGB Black
ARCTIC Liquid Freezer III 420 Pro A-RGB Black
The Arctic Liquid Freezer III 420 Pro liquid cooler with A-RGB in black 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 the latest 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 liquid cooler with A-RGB, black
- 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
- 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 offset mounting for better chiplet coverage. This solution concentrates the cooling performance directly on the hotter spots of the processor, leading to more effective temperature reduction. Heat transfer is further enhanced by the included MX-6 thermal paste.
Power stage and radiator cooling
Right inside 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, contributing to system stability under high load. The cooler uses a 38mm thick radiator. The increased thickness raises the volume of coolant and enlarges the total surface area for heat dissipation.
Simple installation of the Arctic liquid cooler
The manufacturer has connected the fans and hidden their cables within the hose sleeving. This solution significantly simplifies wiring and keeps the inside of the case tidy. The system offers two options for speed control. You can either control all components—the pump, VRM fan, and radiator fans—with a single PWM signal, or split them up and regulate each part separately.
