you need to somehow make a hole for intake and another for exhaust, the fans are better venting if placed both as exhaust and holes are made for passive intake. xhaust should be at top of room where hot air rises
they must be faced outside your cab dumping hot air out, but you need to have your passive intake holes from a different room. best to exhaust out of the house or it will stink
