The water contact area becomes large, so the block can transport more heat quickly from the GPU. The base is T2 cut copper (99.9% purity). The surface flatness is less than 0.01mm. The base conforms better to the GPU so that it can absorb more heat. The copper base is treated with anti-oxidation technology.
