2 holes on the side of the cover, the water flows from the side.
0.4 mm copper columns on the copper base.
The water contact area becomes large, so the block can carry more heat from GPU quickly.
The base is made of T2 (purity of 99.9%) CNC cut copper, processed with anti-oxidization technology.
The surface flatness is less than 0.01 mm. The base can fit the GPU better, so that it can absorb more heat.
