I currently have a CPU waterblock hooked up to my koolance system. Have about 3 ft of hose going to it and 3ft coming back from it. Now with the new cards I am finally getting a GPU block (mcw60). Can I just leave one of the 3 ft hoses going into the CPU block, put the other coming out of the GPU block and put an additional 1 ft section connecting the two? Or is there some other way to hook these all up that would be more thermally efficeint? thanks
