Thought I should get some input as the 19th is coming up fast....

As mentioned in the Rhacodactylus Geckos forum, I'm looking to add a little Crestie to the big herp family at the Phoenix Expo on the 19th. My only concern with adding this type of gecko to the household is the ambient house temperatures.

The bf and I keep the house to ~80 or so since the living room consists of the quarentine snakes and the one bedroom is full of our established collection. We have a second bedroom that I have my indoor rabbits in.

I know that it's recommened to not keep cresties at temps above 80 degrees, and usually the house ambients range from 80-82 (I haven't seem it go over 82 so far this summer/fall and I've been using digital acurite thermometers to measure these ambient temps). The bedroom with the established collection usually is a little cooler (in the mornings its around ~75 while the living room stays closer to 80).

Is it possible to essentially "cool" the air around the tank in which I will keep the crestie without making the whole house/the snakes cooler? Wet washcloth on top of the screen, a frozen water bottle near the tank, a fan on 24/7 blowing air on the tank, etc?

What are the lowest ambient temps that cresties can be comfortably kept in?

I'll be seeing if maybe the closet in the bedroom or the second bedroom with the bunnies will be cooler but if not would a constant 80 degrees be detrimental to the crestie's health? I don't want to run into problems when I have the gecko in hand hence why I'm trying to get this figured out beforehand.

Any ideas?
