Rack set-up, tub air temperature

[Martinotti Reptiles]

What is the average air temperature within your tubs if you keep your geckos in a rack system? I'm just curious to see if mine fall within normal or if I should do more to improve circulation.

I keep my air holes in the front half of the tub for this reason. The air temps stay about 90F for me with floor temps of 96F. Front end of the tubs reach 78-81F, depending on if my windows are open or not.
