Sorry, it doesn't work that way, the radiator cools the fluid as the fluid passes through it, the exception might be when running extremely low velocity fans or no fans at all...
Don't think you grasped it yet......Water is a great conductor of heat. It picks up very quickly and can also get rid of it quickly in various manners and forms. When in a loop, the water is going relatively quick. It does not have to time to sit inside a rad or a block. It picks up heat and transfers it very quickly. Hence why the lack of a temp difference in a loop. It is only when you have very poor flow or circulation in your loop will you see hot spots and usually by then a hose will blow off or a res will crack. A rad basically cools the whole loop down at the same time because of the way water disperses heat so quickly plus it's flow. You are right it's just the 4th dimensional thinking that is lacking which is time. The fluid might pass through the rad 40 times before it drops a degree when your load goes down.
