The temperature difference in a loop is less than 1*c. It doesn't work the way you are thinking. Don't look at at as the water "hearing up", but as the water "carrying the heat" from the blocks to the radiator.
Here are some test results from:

The "best" loop configuration is:
Pump > Radiator > Blocks > Pump,
But any configuration that keeps the tubing lengths short is OK.
Perhaps this will help you also:
