If you go to the lens rental teardown, you can see the rear panel. There is a u-shaped dark section on that rear panel. I believe that is actually a gap in the rear material stuck to that panel and that would have access to part of the processor board. If so, running a peltier cooler there should distribute more of the cooler temps to the main board.
