Geesh, I was not intending to say that the water needs to be near stagnet or barely flowing at all, I was saying that with a heat transfer from the metal to the water there IS a time period that the water takes to absorb the heat from the static source and then there is an idea flowrate at which the water is absorbing to it's maximum capacity and then hopefully being carried off around that point to a cooling medium (heater core). For instance. Take a piece of ice, run it down you're arm really fast several times. Then try taking another piece and running it down your arm much slower, but not slow enough to let it all melt before doing it a couple times and before you reach the end of your arm. And tell me which is going to end up making your arm colder?

There IS a certain point in which flowrate becomes less efficient and I was only saying that with super "~1000GPH+" the pumps people were talking about, they wouldn't be helping much more than the smaller, less GPH producing pumps... which don't add as much heat into the system either.
