HoastfulWatcher i belive this is normal for an old card like that. I have an R9 290X which can run up to 95c while gaming :/
Although i didnt think nvidias cards would go that high in temps, but do note its an old card, it could also be a bad thermal paste job done by the producer of the card. Order some thermal paste and reapply new, but do remember to clean the old thermal paste off.
