Ender 3 in heated cabinet

If I place the Ender 3 pro mechanics in a closed cabinet, with the electronics outside, what is the maximum temperature in the cabinet at which the Ender continues to work properly? In this case, what is the part that can withstand the heat the worst or that breaks first?

How hot do you want to go? PLA parts start to soften at 60°C so there is a start point I suppose…3D printing in a Kiln?

For ABS printing cabinet temperature can get as high as 100 degrees Celsius.
