Description
ModelACFRE00185A
The ARCTIC Liquid Freezer III Pro 420 A-RGB (ACFRE00185A) is a top-tier all-in-one CPU cooling solution combining high-end thermal performance with stunning addressable RGB lighting. It features a 420 mm radiator cooled by three premium 140 mm P14 Pro A-RGB PWM fans, offering powerful cooling performance suited for intense gaming, content creation, and heavy productivity workloads.
This cooler’s PWM-controlled pump ensures consistent coolant flow, efficiently transporting heat from the CPU to the radiator. In addition, a dedicated VRM fan mounted on the pump block actively cools your motherboard’s voltage regulator modules, improving system stability under heavy loads. The addressable RGB lighting integrates easily into RGB ecosystems, enabling synchronized lighting effects through popular motherboard software.
Broad platform compatibility across both Intel and AMD sockets means this cooler fits most modern systems. The included pre-applied MX-6 thermal paste ensures excellent thermal contact from the moment you install the cooler.
Why It’s a Great Choice
Extreme Cooling Performance: The 420 mm radiator paired with three robust 140 mm P14 Pro A-RGB PWM fans provides exceptional heat dissipation — perfect for high-TDP CPUs in gaming, creative, or productivity workloads.
Dedicated VRM Cooling: The integrated VRM fan mounted on the pump delivers targeted cooling for motherboard voltage regulators — enhancing stability and reliability under sustained high power draw.
Balanced Airflow & Acoustics: With strong airflow and static pressure from its P14 Pro PWM fans, the cooler moves heat efficiently while keeping noise levels manageable — ideal for both high-performance and quieter system builds.
Customizable RGB Lighting: The A-RGB Gen2 lighting integrates seamlessly with popular motherboard lighting ecosystems (such as ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, etc.) for synchronized lighting effects.
Wide Platform Compatibility: Supports both modern Intel and AMD sockets, making it versatile for virtually any current desktop build.
Pre-Applied MX-6 Paste: Comes with high-quality MX-6 thermal compound pre-applied, saving time and ensuring immediate optimal thermal contact.
Long Warranty Coverage: The 6-year standard warranty demonstrates ARCTIC’s confidence in the cooler’s build quality and long-term performance.
