When it's 69* and no sun on the smoker, a small pan of ice keeps the temp down nicely. Had under 100* with the smoker setup normally, only the smoke gen plugged in, with 4# of cheese, and 2# of hamburger patties in there Friday Night.
Left my PID Thermocouple in on the bottom rack inverted, but not powered up, ice on next rack up, then the patties, then the cheese on the top rack.
