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.
