How hot is too hot?

As temperatures have been climbing here in AZ, and my Elgoo Saturn in the garage's internal thermometer is measuring 48 degrees C. This has given me issues with builds that are falling off their supports and trouble adhering to the build plate (although seperately, some rafts end up ridiculously stuck- IDK how I can have both problems at once.

Most sources are about resins being too cold to print (which I ran into in the winter and solved with a fermentation belt) and say optimal temp is ~20-30, but I'm well above that. What settings should I change on my printer to assure better outcomes?
