I have seen many GPU water blocks and they all seem to suffer from one basic problem. The fittings increase the space needed to install them so much you loose access to one or even more slots. Why couldn't you bring the water into the block from the edge instead of the top. By machining a slot in the edge of the block You can create a wide rectangular opeaning that extends 1/2 way across the edge of the block. A second rectangular opeaning extends the remaining distance across the end of the block. One side is the inlet and the other is the exhaust. now there is a flattened copper cone that tapers from the round opening of the brass fitting to a narrow rectangular opening opening that solders into the block at the other end. The net effect is the brass fitting is reduced from its normal size and shape and flattened and spread to maintain the same volume but over a wider area, both the inlet and the outlet can be on the same side of the block. the water flow should be faster because of the gradual flair of the copper flair amd the hose fittings are fed from the edge and not blocking any other slots. I visualize a thin water block with a very wide inlet and a narrow center devider wall, the water would flow in a narrow flattened wide stream to the rear of the block then make a 180 turn and flow backto the wide outlet. There would be small ridges to increase surface area and they would be angled to increase turbulance and then to assist in the 180 turn then to direct flow at the exhaust. The tapered flairing inlet and outlets would act like impedance matching devices to increase flow.
I wish I could draw it for you but my drawing sucks.
Anyway what do you think
