Cooler Master, known for producing some of the best CPU coolers on the market, has shared details of its upcoming 360² (360x360mm) AIO liquid cooler at a product launch event in China. According to ITHome, the unnamed cooler has a cooling capacity exceeding 2,000W, which is overkill even for some of the most core-heavy processors on the planet, such as the Intel Xeon, AMD Threadripper, and EPYC series.
The 360² AIO liquid cooler will look familiar to those who attended CES 2026 or saw our coverage of the event. Cooler Master discreetly installed the massive cooler inside the company’s premium Cosmos case. The decision to keep this impressive cooler hidden within the case, rather than featuring it among the company’s main product stack, is puzzling. Regardless of the reason, Cooler Master China has shared details about the extreme cooling solution for high-end workstation and server processors.
The description alone is enough to make you gasp at the cooler’s ambitious design. The concept is straightforward: stack two 360mm radiators to create a massive 360 x 360mm cooling surface with a grid design. It is the largest radiator ever integrated into an AIO liquid cooler, surpassing even today’s 420mm offerings such as the Alphacool Eisbaer Pro Aurora 420 and Corsair iCUE Link Titan 420 RX RGB. If you're a liquid-cooling enthusiast, Cooler Master's radiators will remind you of the German manufacturer Watercool's MO-RA IV series. The difference is that the former comes in an AIO package, whereas the latter is only the radiator and requires a custom loop.

The large surface area of the Cooler Master 360² cooler should provide exceptional heat dissipation. According to Cooler Master's marketing slide, the entire cooling system flaunts a cooling capacity of over 2,000W. The manufacturer's claim is credible, as larger surface areas improve heat transfer. The 360² radiator has an area of 129,600 mm², which is 43% less than the MO-RA IV. However, it's up to 103% larger than the mainstream 420mm AIO liquid coolers.
Radiator size is only one piece of the cooling performance puzzle. The pump plays an equally critical role. Cooler Master has confirmed that its forthcoming cooler will feature a dual-rotor pump design. Dual-rotor pump configurations have proliferated in modern AIO liquid coolers. They deliver higher flow rates, resulting in superior cooling performance and quieter operation. The trade-off, however, is higher costs, as manufacturers must use two pumps instead of one. The approach still has the primary pump housed within the processor block, while the secondary pump can be mounted along the tubing or integrated into the radiator.
