i was just digging through some boxes in the garage and found a couple of old (brand new) 5 inch computer case fans. these things really do move a lot of air. now whether it can handle a 3x5x8 foot room is still in question.

i am gonna run a few tests.... :thumbsup: i happen to have a utility room with a doggie door that is very similar in size as to what i have propsed building.

i can easily stick one of these fans in the doggie door, light up a smoke and hold it as far away from the fan as possible. if it is powerful enough i would expect to the the stream of smoke head off in that direction...
