Ok, I took the fan down and found out the problem. There is no outlet for the air to go outside. All there is is insulation and a ton of wires. I took some of the insulation away and found the hole directly above the fan. It's going to be impossible to vent the air out through the hole. So I think I'm going to cut the top of the fan away and put a computer fan directly on top of the housing. I'll let you know how that works out.
