Pusher - Shroud after or no?

Just a shroud or a shroud and mechanical fan?? Just a shroud probably won't make any difference.

An electric fan (pusher) is my only option with this radiator, so it's going in front. There's no room for a shroud in front so it would be in the normal location after. Just wondering if it would help there or not.
