If you think she might be craving some cooler temps, why not put some ice in her water bowl at one end of the cage...see if she hangs around there?
Some snakes like to wrap their water bowl when they want to be cooler...I don't think a BP would get in, either, even if the bowl is large enough.
You might want to lower the heat mat temp. by a few degrees while your seasonal temperatures are so warm. (do BPs even need a reason to go off
food? probably nothing to worry about...)
