Cooler Master unveils massive 2×2 grid AIO concept for high-end workstations

Cooler Master has showcased a new AIO liquid cooling concept at a recent event in Huizhou, China, breaking away from the traditional linear fan arrangement. Instead of the standard three-fan row, this massive workstation-oriented cooler features four 180mm fans arranged in a 2×2 square grid. This creates a radiator footprint of approximately 360 x 360mm, making it compatible with the manufacturer's recently announced Cosmos case.

According to ITHome (via VideoCardz), this AIO uses a dual-rotor pump and specialised “180×30” fans that reportedly reduce high-frequency noise by 20%. Most impressively, Cooler Master claims the whole cooling system can dissipate over 2000W of heat, positioning it as a specialised tool for extreme workstation builds rather than standard consumer PCs. The square shape presents unique mounting challenges, meaning this likely won't fit in your average mid-tower without some serious modifications.

While this remains a concept for now, the company confirmed that other AIO models shown at the event will hit the market in March, followed by the B360 TV, a CPU cooler featuring a 7-inch 16:9 display, in April 2026.

KitGuru says: As expected from a 360 x 360 AIO cooler, it offers a massive amount of surface area to cool high-TDP CPUs. As far as we know, there isn't any commercially available CPU with a rated 2000W TDP that the cooler is ready for. Still, if it ever comes, Cooler Master is already prepared.
