That effect happens because of the shroud around the rad, not a smaller opening in the front grille. It's great if you can get faster air, but the volume difference is too much to ignore. Plus it's moving just as fast as if you were to have a small opening, and it's on the entire rad, not just a small center portion. Which will allow for better overall cooling.

I would put a bug screen behind the grille. I noticed a lot of bugs collecting on the rad at first which doesn't look very pretty. A dark screen and you can clean it much easier than trying to clean the rad.
