Sure the 'auto' max temp is 65 and it'll probably throttle past that but you can turn those features off and see higher temps without problems. The Tjunction temp is 85 and the most Ive seen is 83 with still no bad effects.

My opinion is 70 is a good regular max to aim for if you dont care about running hot otherwise. i dont think any damage is done at higher temps, even if it did the cpu would probably be worth 20 dollars by the time it showed up.

Past 70 there seems to be stability issues from temp alone that voltage wont compenstate for so well
