Anything below 60° C is considered ok, if you are above this 60° mark under load, I would recommend you start looking for some new cooling.
You can go above 60° without problems, but there really isn't a reason you should be above that. Also keep in mind that the 3200+ runs pretty hot to begin with, my temps jumped considerably when I switched to a 2800+ chip, they just run hotter than previous, slower chips.
