Wow! Just an FYI your hot side should be around 30-33c. Mine rests around 31 and the cool side shouldn't drop below 25, 24 at the absolute lowest!
Sort this out and hopefully your snake will feel more comfortable.
Edit: whoops sorry I can see now you've already been given this advice. But I had the same problem when I got mine. My CHE was only getting up to 28 so I just had to end up getting a higher wattage. Good luck!
