This has been a very interesting thread.
Google pointed me to this Dell document which specs some of their servers
having an expanded operating temperature range
*** based on the amount of time spent at the elevated temperature, as a
percentage of annual operating hours. ***

Another failure I've seen connected to overheating events is AC power
supply failures.

Ugly.
If the batteries that were in the facility's power distribution system were
affected by the heat, then their life is likely significantly shortened.
This is in terms of their capacity to supply power in the event of an outage
and a shortened shelf life.

Honestly, I think your hardware will be fine just like everyone else said
keep an eye on your hard drives they are by far the most sensitive.
Anything not mechanical if it didnt melt you're good.

saw were drive failures and t
