Consider that a typical mirror box has a baffle at the top of the mirror box - see this example:

When the breeze from a powerful rear fan goes past the side of the mirror and hits the inside of the baffle, what does that do to the airflow direction? Will some of the breeze blow across the front of the mirror, assuming the mirror surface is close to the baffle? If not, could the mirror box be designed to direct the air toward the front mirror surface?
