It might be useful - but not necessarily because of any effect on the 
amount of airflow. Air is like water, and follows the easiest route, 
This means it goes past and round objects, often leaving a layer of 
still air on their surface. Still air is a good heat insulator. Sucking 
air tends to produce this sort of flow. The air coming out of a fan is 
turbulent, and this can increase cooling effect by increasing the 
contact between moving air and the hot surface.
