Doesn’t it get too cold and parts start snapping or breaking from thermal expansion around the hot parts?

Extreme overclockers work with liquid nitrogen, which becomes a gas at -196C. The bigger worry there is condensation. 

And if your surrounding is -53C the Hotspots of the cpu / gpu won't be 80C, but 10-15C.

The delta T from ambient should be about the same, regardless of the ambient temperature. Unless you run into thermal throttling at the typical 20-25C room temperature
