The Arctic Liquid Freezer II 420 A-RGB AiO Liquid CPU Cooler offers extensive compatibility, supporting a wide array of AMD and Intel sockets, including AM5, AM4, 1700, 1200, 115X, 2011-3, and 2066 (Square ILM). This ensures adaptability across various system configurations, with ample clearance for RAM modules. Operating efficiently within a temperature range of 0 to 40°C, this cooler maintains optimal performance under varying environmental conditions. Equipped with a 40mm VRM fan and a PWM-controlled pump capable of operating at speeds ranging from 800 to 2000 rpm, it delivers superior cooling efficiency while minimizing power consumption (0.5–2.7 W). The copper construction and micro-skived fins of the cold plate, combined with the included MX-5 thermal paste, ensure efficient heat dissipation. Enhanced by three ARCTIC P14 PWM A-RGB 140mm fans, adjustable from 200 to 1900 rpm and featuring fluid dynamic bearings for silent operation at 0.3 Sone, the Arctic Liquid Freezer II 420 A-RGB Liquid CPU Cooler offers significant improvements. Each fan boasts 12 A-RGB LEDs, providing vibrant lighting effects, while effectively directing airflow through the radiator with a static pressure of 2.0 mmH2O and an airflow of 68.9 cfm. Powered by four-pin connectors, the cooler's fans ensure reliable operation, while the RGB LEDs utilize three-pin 5V-DI-Gnd connectors, drawing 0.4A at 5V for illumination.
The Arctic Liquid Freezer II 420 A-RGB Liquid CPU Cooler boasts enhanced efficiency and quieter operation as standout features. With PWM control regulating the water pump's speed, it achieves significantly reduced power consumption across all AiO components, while also ensuring quieter operation, particularly under low and normal loads.
The Arctic Liquid Freezer II 420 A-RGB All-in-One Liquid CPU Cooler is characterized by its high fin density, allowing for a larger volume of water within the circuit and significantly expanding the cooling surface area. Compared to copper or aluminum, which have lower heat capacities than water, this design enables a slower and more limited increase in temperature during the time-limited turbo mode of modern CPUs, potentially by up to 5°C.
You can rest assured knowing that maintenance concerns are minimized with the Liquid Freezer II 420 A-RGB's fiber-reinforced 45 cm tubing, which effectively resists coolant evaporation. This feature also facilitates installation even in spacious cases, providing flexibility and convenience. Furthermore, our advanced cable management system conceals the RGB and PWM cables of the radiator fans within the sleeve, ensuring a tidy appearance. With only two connectors requiring connection to the mainboard and no extra cables to conceal, installation is straightforward and results in a clean and organized setup.
The Arctic Liquid Freezer II 420 A-RGB Liquid CPU Cooler comes equipped with illuminated P-fans that are pre-mounted on the radiator straight from the factory. These fans were developed with a strong focus on delivering focused airflow and high static pressure, ensuring efficient cooling performance even when encountering elevated air resistance. As a result, the P-series fans excel in providing effective cooling solutions, making them especially well-suited for use on heatsinks and radiators.
