You're going to scare the kids to death...
85C is VERY hot... usually found in high ripple current / high ambient
temperatures that a synth will never see (well... MAYBE if you play
daytime outdoor concerts in Death Valley often).
Capacitor life increases exponentially (close enough) with decreasing
temperature... and most synth apps are very low ripple current (except
switching power supplies, which we loathe...) so life should be probably
10-20 years minimum.
I don't 'shotgun' replace electrolytics... I only replace as they fail. MOST
will never (well...hardly ever...) fail. If it is mission critical (like an
aging power supply) then change it.
