Hi all- long time lurker here.. I have an insulated 2 car garage that is directly underneath our bedroom.. and it gets hot!....what I am planning on doing is installing two temp controlled "attic vent fans" each on opposite sides of the garage walls up as high as I can get em.. Set their turn on temp to 80-85 or so and see if I can get one to push air out and one to pull air in...as frequently it is 10-15 degrees cooler outside than it is in the garage.. sooo I'm here for you guys to shoot down this idea before I do it or give me a better option.. I'm not going to do A/C mainly because it is only a problem for about two months out of the yr..and frankly that would seem like overkill.. I'm just looking for a clean solution to vent the garage automatically.. I'm in denver so it is normally dry ( not this yr though) 
thanks!
thanks!
