Coolant return line (top or bottom of radiator?)

Does it matter whether I run the coolant return line from the turbo to the top or the bottom of the radiator? Thanks!

The most efficient spot to return it is the top of the radiator since the it cools from the top down. However, returning it to the bottom will work also.

It doesnt really matter in theory. The purpose is to cool after engine shutdown through convection. I guess putting it in the top would be optimal.
