Default cabin exhaust fan

My small cab has a door and thats it. No hatch, not vents. I've got a small fan that does ok but I'm trying to improve the air flow for my daughter. I'm thinking about installing a small fan on the back wall of the cabin to pull air in through the door and push air into the bilge under the cockpit. My first thought is a big 12v computer cooling fan like 4"x4" or even bigger if I can find it. It would use almost no power, be very quite and I could cover it with a speaker grill or something similar. I dont know if it would move enough air to make a difference. Any other ideas for fans I could use to mount on the plywood cabin wall? I would need something I could leave on over night and still be able to start my engine the next morn.

I used a pair of 4 inch dc computer fans in my old powerplay for exactly that reason. Quiet, brushless fans, very low power usage. I mounted one one each side of the cabin bulkhead, one pushing air in and one sucking air out. It actually moves a fair bit of air that way. Its no hurricane force wind but the cabin definately stayed fresher on overnighters.
