Testing Lego in Cold and Hot Temperature

I tested my wheel spinner and hoist at -20 degrees Celsius outdoors (lovely Finnish weather in January), 20 room temperature, and 60 inside a sauna. How the temperature affects top speed and max hoist weight? Will something break? The spinner results: -20C 3100rpm () 20C 4800rpm () 60C 4700rpm () 20C 4400rpm (fixed voltage) The hoist results: -20C 101kg () 20C 132kg () 60C 95kg () 20C 101kg () (motor 60C) 20C 122kg ()
