In my box setup i installed a bathrroom fan into the roof that moves 70 cfms of air, this creates a pretty good constant flow of fresh air moving in and out of the box. Sense im limited on space i was gonna screw a fan directley to the roof in a fixed position to keep a air movement along with the bathroom vent fan, but if its not neccesary i would rather save the hassle. So how is a fan beneficial?
