Just curious, as I have never heard that rapid cooling can damage equipment (other than sticking in in liquid nitrogen or something where it gets very brittle) can damage anything, can you source that?

My source is experience mainly, though in terms of electronic equipment Differential Cooling would be the main problem with any rapid cooling technique, which may lead to cracked solder joints and burst electrolytic capacitors amongst other things (though in this case, burst caps are likely anyway). Natural cooling of a modern power brick should reduce - though not eliminate - the chances of problems caused by Differential Cooling.

Why doesn't power adaptors have any sort of ventilation to cool down??? Literally a completely sealed black box. That means eventually, it will overheat. Can't be good design.
