I think humidity and condensation is well understood and indeed
documented but by NEBS and vendors as verboten.

I am more interested in temperature changes when not condensating and
causing water damage. Like we could theorise, some soldering will
expand/contract too fast, breaking or various other types of scenarios
one might guess without context, and indeed electronics often have to
experience large temperature gradients and appear to survive.
When you turn these things on, various parts rapidly heat from ambient
to 80-90c. So I have some doubts if this is actually a problem you
need to consider, in absence of condensation.
