what I meant is that if you filled the tubing to the tip top with liquid, it wouldn't make a difference between that and the same res/pump/rad with less tubing filled to the top with liquid, you're misunderstanding me, not the other way around
No, I understand the discussion just fine. Granite3 made good points by listing the quantity of fluid, the size of the radiator and the amount of air flow through the rad. He possibly assumed that the liquid flow and the temperature delta was adequate and one can't really assume that. Your reply to him was overgeneralized and I've already responded to the first sentence, so now look at the next bit where you wrote:
"The amount the w/c kit will cool the cpu/what ever is directly proporional to how well the coolant can be cooled, not how much, a good pump can take care of that."
Within limits, this is true, but you have to look at the practical aspects. In order to remove enough heat to cool the CPU, you need adequate radiator surface area and that is in part determined by the difference in temperature between the air and the rad. If your claim that the amount of water doesn't matter, then all you have to do is design systems with smaller and smaller liquid capacity. At some point, the diameter of the tubing and the radiator passages will have to get pretty small and when that happens, you're not going to be able to deliver adequate liquid flow with a practical pump and tubing setup.
I've cooled reactors that put out kilowatts of heat by using HSFs, water, TECs, LN2, you name it. As you drop the liquid volume in a WC loop, it becomes increasingly difficult to remove heat, period. If you don't believe me, then go do what I've done and try to build miniaturized cooling systems for aircraft applications where payload restrictions dictate the mass and size that's allowed. Go do the development, then come back and try to say liquid volume doesn't matter. Believe me, it does.
