Not all the blood goes the kidneys but because it continually mixed its all constantly cleaned.

No no no.
This has come up before, I will try and find it.
Neglecting the change in transfer coefficients with varying flow rates, there would be no difference in water temperature if you varied the speed of the flow through the rad.
Goes slowly, the rad dissipates more energy from each unit volume of water, but fewer unit volumes of water flow through the rad.
End result, no change.
Now add the fact that at higher flow rates, the efficiency of the convective heat transfer from water to rad is improved, so now we still have the same amount of thermal energy dissipated, but the water temp will be lower.
