ARCTIC Liquid Freezer III Pro 420 A-RGB 420mm AIO CPU Cooler 3x 140mm Fans Black

The ARCTIC Liquid Freezer III Pro 420 A-RGB AIO liquid CPU cooler is one of the strongest choices for anyone who wants low CPU temperatures and quiet operation in a gaming or workstation build. It uses the largest radiator in the series (420mm) with three 140mm fans and is built for demanding processors such as Core Ultra 9, Core i9 and Ryzen 9 that need stable cooling under long, heavy loads. On this page you will find the full ARCTIC Liquid Freezer III Pro 420 A-RGB specifications and its price in Iraq, with cash on delivery available.

Design

The design centres on a large aluminium radiator measuring 458 × 138 × 38 mm, paired with 500 mm tubes that give you freedom to mount it at the top or front of the case. The pump head carries a small fan that cools the VRM area around the socket, a rare feature in AIO coolers that helps protect the motherboard when overclocking. The three P14 Pro A-RGB fans add colourful lighting that you control through the motherboard's A-RGB header.

Cooling performance

The three fans spin between 400 and 2500 RPM, delivering up to 110 CFM of airflow and 5.2 mmH2O of static pressure, enough to push air efficiently through the thick radiator fins. The pump runs between 800 and 2800 RPM under PWM control from the motherboard, so it stays quiet in everyday use and only speeds up when needed. The result is lower temperatures and higher sustained clocks during gaming, video editing and rendering.

Compatibility and installation

It supports Intel LGA1851 and LGA1700 as well as AMD AM5 and AM4, and ships with a contact frame for Intel CPUs that improves contact with the cold plate and prevents the processor from bending. Before buying, make sure your case supports a 420mm radiator (three 140mm fan slots), which is larger than the common size.

Key specifications

• Radiator: 420mm aluminium, 458 × 138 × 38 mm

Technologies explained

• AIO: a sealed, ready-to-install liquid cooling loop that needs no filling or coolant maintenance.
• FDB (fluid dynamic bearing): a fan bearing that is quieter and longer-lasting than standard sleeve bearings.
• PWM: smart speed control from the motherboard based on CPU temperature, so fans stay quiet at light load.
• A-RGB: addressable lighting where each LED's colour can be controlled and synced with the rest of the build.
