I'm not pretending anything. First, I can't even figure out what you're talking about. Second, my primary point has always been that you must consider the operation of the WC as a whole when tying to determine the effects of a change. Nothing happens independently.

I'm sorry to say, but your grasp on the principles involved is lacking.
I will be the first to admit that there are effects which will alter the theoretical outcome, as with everything, but the theory still stands and is relatively accurate.
As I say over and over, yes you do need to consider the whole system, but the only data we know is the flow rate, the efficiencies, the heat load and the ambient air temp.
The only things we can directly control are the heat load, the ambient air temp and the flow rate. (air and water)
The efficiencies are determined by the flow rates, which in turn determine the delta T required to shift the set heat load.
THIS IS HOW IT WORKS.
Consider this. There are equations for the rate at which the water cools in the rad, the rad temp relative to the ambient temp, the water temp relative to the rad temp, the waterblock temp relative to the water temp and the cpu temp relative to the waterblock temp.
This is essentially a set of simultaneous equations which can be solved. However, the only temperature we know is the ambient air temp, so we MUST work backward from this.
Is this clear.
The thermodynamic principles I outlined earlier are correct.

Also, the temperature of the water drops because you now have the same amount of heat absorbed over a larger mass.

Now who's smoking what?:shrug:
By increasing the flow rate, have we mysteriously added more water?
The only concept you need to grasp is that watercooling is all about different components/mediums reaching equilibrium temperatures relative to the only defined temp, the ambient air, such that the differences in temps with the corresponding heat transfer coefficients result in the treansfer of the defined heat load.
Changing variables such as flow rate air or water, will increase the heat transfer coefficients, thus reducing the temperature differences.
Note this doesn't take into account heat from the pump, though differnt pumps may produce the same flow with different heat input. This is one of those real world factors that is hard to control. but hey, lets get the basics sorted first.
