ARCTIC Liquid Freezer III Pro 240 AIO CPU Cooler
A performance-focused 240mm all-in-one CPU liquid cooler featuring a 38mm radiator, dual P12 Pro fans, integrated VRM cooling and offset CPU mounting.
ARCTIC Liquid Freezer III Pro 240: Serious 240mm CPU Cooling
The ARCTIC Liquid Freezer III Pro 240 is a multi-compatible 240mm AIO CPU liquid cooler designed for modern high-performance desktop systems. Its cooling assembly combines a 38mm-thick aluminium radiator with two high-speed P12 Pro 120mm fans, providing substantial radiator surface area and high static pressure for demanding CPU workloads.
ARCTIC also integrates a dedicated PWM-controlled VRM fan above the CPU block, while the offset mounting system positions the cold plate toward the CPU hotspot. The cooler supports AMD AM5/AM4 and Intel LGA1851/LGA1700 platforms.
Key Features
38mm Premium-Class Radiator
The 277 × 120 × 38mm aluminium radiator is thicker than conventional 27mm AIO radiators and is designed to provide greater liquid volume and heat-dissipation capacity.
Dual P12 Pro Fans
Two pre-installed P12 Pro fans operate from 600 to 3000 RPM, producing up to 77 CFM airflow and 6.9 mmH₂O static pressure.
Integrated VRM Fan
A dedicated PWM-controlled fan on the CPU block directs airflow toward the motherboard VRM area to help manage local component temperatures.
Offset CPU Mounting
The cold plate is offset toward the CPU hotspot on supported AMD and Intel platforms to improve contact with the area where heat is concentrated.
Intel Contact Frame
The included contact-frame approach is designed for compatible Intel LGA1851 and LGA1700 processors to provide optimized contact pressure distribution.
Integrated Cable Management
Fan wiring is integrated into the sleeving, helping keep the installation cleaner and reducing cable clutter around the radiator and motherboard.
Cooling Technology & Performance Hardware
Liquid Freezer III Pro 240 combines a thick radiator, high-pressure P12 Pro fans, a dedicated VRM fan and a copper micro-skived cold plate. The pump operates from 800–2800 RPM, while the radiator fans can reach 3000 RPM under PWM control.

Before You Build
- Confirm that your cabinet supports a 240mm radiator and has sufficient clearance for the thicker 38mm radiator.
- ARCTIC specifies that the Liquid Freezer requires at least 63mm of clearance for installation.
- Check motherboard compatibility carefully, particularly around large M.2 heatsinks near the primary CPU socket.
- The cooler supports AM5, AM4, LGA1851 and LGA1700 with the appropriate mounting hardware.
- The radiator and fans are pre-installed and pre-wired to simplify installation.
- The package includes ARCTIC MX-6 thermal paste.
