What temperature rating capacitor would you expect to be fitted and why would it
'boil' at 105 deg C?

I'll have a go and say '105 DegC' cap and it would 'boil' (read not be
happy at ..) if 105 DegC was the temperature of the fitting and
therefore the temperature it was working at? Maybe the caps are more
susceptible to overtemp than most the other components?

I'm not confirming (scientifically) that that's what will happen but
that it seems logical as a suggestion to why such things might fail
prematurely if they are allowed to run hotter than they 'should'?
