Description

ARCTIC Liquid Freezer III Pro 420mm AIO CPU Liquid Cooler

ACFRE00181A

The ARCTIC Liquid Freezer III Pro 420 (ACFRE00181A) is a high-end all-in-one (AIO) liquid CPU cooler engineered for extreme thermal performance. Its 420 mm radiator combined with three high-efficiency 140 mm P14 Pro PWM fans delivers exceptional cooling capacity — perfect for high-end gaming systems, heavy productivity workstations, and overclocked CPUs that generate significant heat.

The cooler’s PWM-controlled pump ensures consistent coolant flow, and a unique integrated VRM fan on the pump block actively cools the motherboard’s voltage regulator modules, improving system stability under sustained heavy loads. Compatibility spans the latest CPU sockets, including Intel LGA1851, LGA1700, LGA1200 and AMD AM5, AM4, making this AIO cooler versatile across current platforms.

Included pre-applied MX-6 thermal paste ensures strong initial thermal contact without the need for extra thermal compound application, making installation easier and more efficient.

Why It’s a Great Choice

Extreme Thermal Performance: The 420 mm radiator combined with three high-efficiency 140 mm P14 Pro PWM fans ensures powerful heat removal — ideal for CPUs with high TDP or for users pushing their systems with overclocking or extended workloads.

Dedicated VRM Cooling: A standout feature of the Liquid Freezer III Pro series is the integrated VRM fan on the pump block, which actively cools the motherboard’s voltage regulators for enhanced stability under sustained performance loads.

Broad Platform Support: Compatible with both current Intel (LGA1851, LGA1700) and AMD (AM5, AM4) platforms, this cooler is capable of supporting a wide range of builds with future-ready versatility.

High Static Pressure Fans: The included P14 Pro PWM fans are engineered for strong static pressure and airflow through the dense radiator stack, maximising cooling performance while keeping noise manageable.

Pre-Applied MX-6 Thermal Paste: Having MX-6 thermal compound pre-applied reduces installation time and provides excellent thermal conductivity right from the start.

Quiet, Efficient Operation: Even under heavy system load, the pump and fans operate with optimized PWM control, keeping noise levels sensible for demanding environments.

Long Warranty: A 6-year manufacturer warranty provides confidence in long-term reliability and support — excellent for high-performance and enthusiast builds.
