I have a standing thermometer that measures the cool side which I try to keep at 75-80. If I leave the red light lamp on, it can get things too hot, so I turn it off when I leave for work when I can't see it. The temp doesn't go any lower than 70.
(And I have a temp gun which I use all over and to verify the temp in the warm hide, which has a warm spot of 93 and is generally 90)
The clicking happens very off and on, and it didn't matter what temp. It's been about a week now since I've heard it. And since my apartment is kept no lower than 70 (rather than 60-80 at my previous place) I think I may have found a solution.
