Cooler Master's 360x360mm AIO Liquid Cooler Targets Extreme Workstation CPUs

Cooler Master has unveiled an unprecedented cooling solution at its China product launch event - a massive 360x360mm AIO liquid cooler that pushes the boundaries of what's possible in consumer-grade liquid cooling. The unnamed cooler, simply designated as 360², boasts a cooling capacity exceeding 2,000W, making it suitable for the most demanding workstation and server processors available today.

This colossal cooler made its first appearance at CES 2026, where Cooler Master discreetly installed it inside the company's premium Cosmos case rather than featuring it prominently in their main product lineup. The decision to keep such an impressive cooling solution hidden within the case rather than showcasing it has raised eyebrows among enthusiasts and industry observers alike.

Revolutionary Design Concept

The 360² represents a significant departure from conventional AIO designs. Rather than following the trend of increasing radiator thickness or adding more rows of fins, Cooler Master has opted to dramatically expand the surface area by stacking two 360mm radiators to create a massive 360 x 360mm cooling surface with an innovative grid design.

This approach results in a radiator with 129,600 mm² of surface area - the largest ever integrated into an AIO liquid cooler. To put this into perspective, the 360² offers 43% less surface area than Watercool's MO-RA IV series (a popular choice among custom loop enthusiasts) but provides up to 103% more cooling surface than mainstream 420mm AIO offerings from manufacturers like Alphacool and Corsair.

Technical Specifications and Performance

Cooler Master's claim of over 2,000W cooling capacity is supported by the fundamental principles of thermodynamics - larger surface areas facilitate more efficient heat transfer. The company has backed this up with a comprehensive dual-rotor pump design that has become increasingly common in high-performance AIO coolers.

The dual-rotor configuration offers several advantages:

• Higher flow rates for superior cooling performance
• Quieter operation through more efficient liquid circulation
• Better heat distribution across the massive radiator surface

The trade-off for this enhanced performance is increased cost, as the design requires two pumps instead of one. The primary pump remains housed within the processor block, while the secondary pump can be mounted along the tubing or integrated into the radiator itself.

Fan Configuration and Noise Management

Perhaps the most intriguing aspect of the 360² is its fan configuration. The cooler utilizes four 180mm fans that appear to conform to the 18030 specification - a size more commonly found in industrial applications such as RV furnaces or automotive cooling systems rather than PC components.

Cooler Master claims these fans deliver up to 600 CFM of airflow, though the company emphasizes that static pressure is the more critical metric for radiator cooling applications. The fans achieve up to 20% reduction in high-frequency noise compared to conventional designs, addressing one of the primary concerns with large, high-airflow fans.

The standard configuration includes four fans, but users can add four more for a push-pull setup, bringing the total to eight fans. While this configuration theoretically improves cooling performance, Cooler Master acknowledges that the real-world benefits may not always justify the additional complexity and noise.

Compatibility and Installation

During the demonstration, Cooler Master showcased the 360² with a 96-core AMD Ryzen Threadripper Pro 7995WX processor, highlighting its capability to handle extreme multi-core workloads. However, it remains unclear whether the cooler will support Intel Xeon platforms, which would significantly expand its potential market.

Given the unique radiator design and massive dimensions, the 360² requires a large case with ample space for installation. Cooler Master has demonstrated compatibility with the Cosmos 700 series cases, specifically the C700P and C700M models, which offer the necessary clearance and mounting points.

Market Position and Industry Impact

The 360² represents a fascinating middle ground between traditional AIO coolers and custom water cooling loops. By offering a pre-assembled solution with radiator dimensions approaching those of custom setups like the Watercool MO-RA series, Cooler Master is targeting enthusiasts who want extreme cooling performance without the complexity of building a custom loop.

This approach could potentially disrupt the high-end cooling market by making extreme cooling more accessible to enthusiasts who lack the expertise or desire to build custom loops. The all-in-one nature of the solution eliminates concerns about leaks, pump selection, and tubing routing that often deter users from exploring custom water cooling.

Future Availability and Pricing

As of now, Cooler Master has not announced pricing or specific availability dates for the 360² AIO liquid cooler. The company has been contacted for additional details regarding market release and pricing, with updates expected once official information becomes available.

The introduction of the 360² signals Cooler Master's commitment to pushing the boundaries of AIO cooling technology and addressing the needs of users with extreme cooling requirements. Whether this massive cooler finds widespread adoption or remains a niche product for the most demanding users, it represents an exciting development in the evolution of PC cooling solutions.

For enthusiasts running high-core-count processors in demanding applications such as 3D rendering, scientific computing, or content creation, the 360² offers a compelling solution that combines the performance of custom loops with the convenience of AIO designs. As workstation CPUs continue to increase in core count and power consumption, solutions like the 360² may become increasingly relevant in the enthusiast and professional markets.
