No, this is incorrect. The pins and fins in commercial waterblocks, while having the side effect of slowing down the water flow, are there to create a greater surface area for the water to contact, allowing more heat to transfer. Also, the amount of heat taken away by the watercooling is the same regardless of the speed of the water. If the water is moving slowly, then it may remove more heat, but it will go through the radiator fewer times. However, if the water is moving more rapidly, it may remove less heat, but it will go through the radiator a greater number of times.
By your logic, if slower water absorbs more heat than fast water, shouldnt slower water dissapte heat more in the rad?
so, even if it goes through more times, the faster it goes through, the less heat will dissapate from it. Im sure there is some middle ground with marginally better results than the est, but i bet the point is so moot. But what do i know? I dont run WC anyways
LOL. I actually run a Swiftech Apex. But yea, the main performance increase comes in head pressure. This is why pumps such as the D5 outperform AC pumps with lesser head but higher flow.
What about you re-build the design using copper. Run something like Prime95 with both of the blocks attached (one after another of course ) and compare the temps?
