Those temps are okay with a new machine. If you recap the whole thing, you will probably be just fine. I think under operation with high heat may speed up cap failure. But at cooler temps, probably fine.

Yes, on the hottest days when it is 110 outside it gets up to about 90 in the garage/workspace.  I'll be sure to have a fan going on those days OR bring it inside for the month of August and September.  

I did re-cap the entire motherboard (w/ Tantalum capacitors) and most of the analog board. I believe tantalums are not likely to leak like the electrolytic ones ...but will still bring my machine in during the hottest months.  Okay, heat bad ...cold not so bad.
