I guess that would be a rather serious problem if the temperature
inside your computer case averaged 105°C = 221°F.
Seen a modern mainboard recently?
Certainly.
Voltage regulation MOSFETs with
heatsinks on, some with their own extractor fans? Heat coupled to the
capacitors by a few millimetres of thick copper PCB trace for excellent
heat conduction?
Have you put a thermocouple on the capacitors?
You need a themocouple and a suitable meter for that ! ;~)

Really? ;-)
Of course many, if not most, portable multimeters have type K
thermocouple inputs (of dubious accuracy, but good enough for this
sort of thing) and many are supplied with a bead thermocouple.
Funnily enough, often some of the cheapest ones have the thermocouple input but
I used to keep a supply of type-K themocoouples anyway. I like keeping an eye
on temps.
