I'm gonna try out the min/max thermometer. I'll hold off on smacking the bean counter for now. After all, I was allowed to basically get the system I wanted (within reason) almost without question. Of course that may be why now I'm having trouble getting another 10K.

Our ventilation system works on the same principle as your fan idea. One thing lacking right now is a vent on the door of the room to let in cooler air, thus the reason I have to leave it open. But I feel certain the room will reach 90 F during the summer (even with the vent in the door) and I'm afraid it may produce more wear on the hardware than I'd like.

Thanks for the suggestions. I'll PM you if I have any more specific questions. CXGJarrod, I'll let you know how it goes.
