My ball python is also in a T10. My probe is located on the cool side. I have it set to 80 in the part of the enclosure that gets the absolute coolest temp. The hot side is like yours... a little close to 100 literally at the top touching the rhp. The area below it is about 90. Inside the hide is a little cooler, usually 85 give or take... sometimes higher, sometimes lower. Has worked great for me like this for about a year, which is when I put my girl in there. I am no expert, but your setup seems fine to me.![]()
