Cooler Master’s Square Radiator AIO: Redefining High-Performance Cooling
Innovations in PC cooling continue to push boundaries, and Cooler Master has recently made waves with a groundbreaking concept: a square radiator AIO cooler capable of managing over 2,000 watts of thermal output. The Cooler Master 360² challenges conventional rectangular radiator designs and delivers impressive cooling efficiency for demanding workstation and server environments.
The Unique Design of the Cooler Master 360² Radiator
Unlike traditional all-in-one (AIO) liquid coolers, which typically feature elongated rectangular radiators ranging from 240mm to 420mm in length, the Cooler Master 360² sports a distinctive 360 x 360 mm square radiator. This bold design stands out visually but more importantly provides enhanced surface area for improved heat dissipation in a compact form factor.
Mounted atop the square radiator are four large 180 mm fans, each with an uncommon thickness of 30 mm. This fan configuration departs from the usual setup of three 120 mm fans and offers notable advantages, including reducing noise levels by up to 20%, particularly within the frequencies considered most intrusive by users.
Advanced Cooling Performance for High-Core-Count CPUs
The Cooler Master 360² is specifically engineered to handle the demanding thermal loads generated by modern high-core-count CPUs commonly found in workstation and server builds. Featuring a dual-rotor pump, this cooling system maintains robust coolant flow rates even under continuous heavy workloads, ensuring consistent and reliable thermal management.
First revealed publicly during CES 2026, this AIO cooler can dissipate heat exceeding 2,000 watts, a feat that marks it as an industry-leading solution for extreme thermal challenges. Currently showcased inside a Cooler Master Cosmos series chassis, compatibility may be limited to select cases due to the unique radiator dimensions.
Market Availability and Future Prospects
Details about pricing, launch dates, and global availability remain undisclosed. However, it is anticipated that the Cooler Master 360² will initially target niche professional markets requiring top-tier cooling solutions rather than general consumer segments. Enthusiasts and customers with high-performance workstation needs can expect this unit to add a fresh option to the often predictable liquid cooling landscape.
