Water Cooler Arctic Freezer III Pro 240

ARCTIC Liquid Freezer III 240 A-RGB – High-Performance 240mm AIO

The ARCTIC Liquid Freezer III 240 A-RGB is a high-performance all-in-one liquid CPU cooler designed for modern gaming PCs and demanding desktop systems. Its 240mm aluminium radiator is paired with two P12 PWM A-RGB fans, providing efficient heat dissipation while adding customisable lighting to the build. The cooler supports Intel LGA1851 and LGA1700 as well as AMD AM5 and AM4, making it compatible with a wide range of current desktop processors. The black finish gives the cooler a clean appearance that works naturally with dark gaming builds, while the integrated A-RGB lighting allows it to be synchronised with compatible motherboard lighting systems. With its integrated pump, VRM fan and copper cold plate, the Liquid Freezer III 240 A-RGB is designed as a complete CPU cooling solution.

Efficient Pump and Copper Cold Plate

The cooler features a PWM-controlled pump operating between 800 and 2800 RPM, providing adjustable cooling performance according to processor load. Heat is transferred through a copper cold plate with micro-skived fins, designed to maximise the contact area between the cooling plate and the liquid inside the loop. ARCTIC also includes MX-6 thermal compound, with 0.8g supplied for installation. An integrated VRM cooling fan operates between 400 and 2500 RPM and directs additional airflow towards the voltage regulation area around the CPU socket. This distinctive design provides active cooling not only for the processor but also for the surrounding motherboard VRM components, making the Liquid Freezer III particularly suitable for systems built around higher-performance CPUs.

Dual P12 PWM A-RGB Fans

The 240mm radiator is equipped with two P12 PWM A-RGB fans, each capable of operating between 200 and 2000 RPM. The fans deliver up to 48.82 CFM of airflow and up to 1.85 mmH₂O static pressure, providing the pressure required to move air effectively through the radiator fins. They use Fluid Dynamic Bearings and standard 4-pin PWM connections for speed control. Each radiator fan features 12 A-RGB LEDs, connected through a standard 3-pin A-RGB connector. This allows the lighting to be controlled through compatible motherboard software and coordinated with other illuminated components. The result is a cooling system that combines strong radiator airflow with customisable RGB lighting while maintaining the understated appearance of its black housing.

240mm Radiator and Flexible Installation

The aluminium radiator measures 277 × 120 × 38mm, providing a substantial cooling surface while remaining compatible with cases designed for 240mm AIO solutions. The cooler uses 450mm tubing, giving builders flexibility when positioning the radiator inside the chassis. ARCTIC integrates the cabling into the cooler design to help reduce cable clutter around the CPU area. The Liquid Freezer III 240 A-RGB supports both an all-in-one 4-pin PWM connection and a split configuration using three 4-pin PWM connectors, allowing the pump, VRM fan and radiator fans to be controlled separately when required. The A-RGB lighting uses a standard 3-pin 5V A-RGB connector, making it straightforward to integrate with compatible motherboard lighting headers.

Intel and AMD Compatibility

The Liquid Freezer III 240 A-RGB supports a range of current desktop CPU platforms, including Intel LGA1851 and LGA1700 alongside AMD AM5 and AM4. This makes it suitable for modern Intel Core and AMD Ryzen gaming, workstation and enthusiast systems. The 240mm radiator format provides a practical balance between cooling capacity and case compatibility, fitting many systems where a larger 280mm or 360mm radiator may not be suitable. The cooler is supplied with the required mounting hardware for its supported platforms, while the included MX-6 thermal compound simplifies the installation process. As with any liquid cooler, available radiator clearance should be checked against the chosen case and motherboard configuration before installation.

Black A-RGB Design and Six-Year Warranty

The black ARCTIC Liquid Freezer III 240 A-RGB combines a discreet dark finish with integrated addressable RGB lighting, making it suitable for both subtle and highly illuminated gaming builds. The VRM module includes 12 A-RGB LEDs, while each radiator fan also features 12 A-RGB LEDs, giving the cooler a coordinated lighting effect across the pump area and fans. The complete unit weighs approximately 1490g and uses 450mm tubing for installation flexibility. ARCTIC backs the Liquid Freezer III 240 A-RGB with an extensive 6-year manufacturer warranty. With its 240mm radiator, high-speed P12 fans, integrated VRM cooling, copper cold plate and broad AM4, AM5, LGA1700 and LGA1851 compatibility, it provides a capable cooling platform for modern PC builds.
