The weather was not extremely oppressive (it was pretty cool out by midnight, actually), but one thing that was amazing despite the fact that it wasn't a really bad day is that the fan cooled the house donw in about 5-10 SECONDS. Not minutes. If the outside air was very warm and humid, it is not clear how good such a thing would be. It's main advantage is that virtually instaneously the temperature inside the house and the temperature outside the house become equal. Mike
