TK,
A fluid will flow as fast as the smallest restriction.... regardless. Whether your running a 2 1/2 inch fire hose or a 3/8 vinyl hose through a 3/8 restriction the flow will still be the same given the same pressure. This is analogous to volts vs amps ironicly where volts is pressure and diameter is amps.

I read of one guys build (not on PCMechanic) who converted his liquid cooling system from 3/8 to 1/2. The coolant blocks over the CPU and graphics cards remained 3/8. He used 3/8 to 1/2 adapters to connect the larger 1/2 inch tubing to the blocks and pump. What happened is he saw no improvement in cooling and with the larger bend radius of 1/2 tubing, he could not get his case door closed! It looked like a green octopus trying to escape from a cage. I wish I could remember where on the internet saw it.

I bet if you go to the Koolance, Zalman or even the Thermaltake website, you can get ideas on how to build a 1/2 inch system from scratch using all 1/2 inch components.
