A relatively new player in the water cooling industry, Comino, has recently introduced its latest product: a water block for the NVIDIA H100 PCIe accelerator card. The new block provides full coverage with cooling to the GPU, GDDR, and VRM. In the design, Comino only used non-corrosive materials such as copper, stainless steel, aluminium, and Plastic. The core of the block uses copper, while the frame and backplate use aluminium. The company claims that at a coolant temperature of 20°C, the temperature of the GH100 chip with Comino water blocks will be 30º-40°C.

Comino uses "deformational cutting" technology to create a copper fin as thin as 0.1 mm with a 0.1 mm channel and 3 mm height. In Comino water blocks, micro fins are optimized for a low-pressure drop with a thickness of 0.25 mm, channel - 0.25 mm, and 2.7 mm height. The block itself is a single-slot solution with fitting adapters on the back and a 90º adapter option for workstation implementation. More information is available on the Comino website.
