Airflow from small pressure differentials is an amazing phenomenon. So many air-cooled VW's back in the day ran hot from a bad engine seal separating the top half from the bottom which allowed for the cool air to be ducted to the cylinder fins etc.

Also same deal on some air cooled electric motor drives we used to make. You can just about double the useful cfm through a heat exchanger with the leaks eliminated.
