Actually that analogy isn't accurate. I had said. "Correct me if I'm wrong, but isn't the ideal cooling situation when you have two fluids exchanging heat to have the fluid BEING cooled to move slowly, and the fluid DOING the cooling moving fast"
In your analogy the thing being cooled is the CPU, which is idle, and the thing cooling is the liquid which is moving fast(preferable)
I'm not trying to sit here and argue, so don't misunderstand. Any reference to those tests? Links preferably
