Cooler Master recently showed off a host of fancy AIO liquid coolers at CES 2026 , but more recently, at a recent event in Huizhou, China, Cooler Master debuted a new square 360 mm AIO radiator that appears to be designed specifically for oversized workstation builds. In the slides, shared by IT Home and VideoCardz , Cooler Master claims that the square AIO is capable of dissipating up to 2000 W of heat, suggesting that the cooler is destined for servers and high-core-count CPUs.

The esoteric use case is only matched by the radiator's bizarre fan configuration. Instead of the 3×3 configuration of 120 mm fans that you might expect given the 360 moniker, the concept AIO uses four 180 mm fans. This is likely at least in part because the edge mounting configuration was less intrusive than having supports for the fan mounts that would not make contact with the radiator's edges. Cooler Master also claims that the peculiar fan configuration reduces low-frequency noise by as much as 20%, although there's no information about the comparison configuration. The AIO was also presented in a Cosmos PC case, although whether this case was stock is unclear.
