Liquid Cooled GPU

Water flow is an important part of the system... based on both the available flow area and flow velocity, the more you restrict the system by introducing more water blocks or smaller tubing the harder the pump has to work.
 
well maybe that would speed up the circulation possibly to do a 1/2 to a 3/8??
No.. 1/2 is larger than 3/8.. water would have to move faster for the same volume to pass over a given time. However, that means resistance increases dramatically.. definitely not good if you've got multiple items in the loop - CPU block, chipset block, GPU block, radiator...
