Even if it is that high I think it has the same Tjuntion technology as the intel CPU so it would shut it self down if it reached it's max Temp. I would say between 30-60°c is fine. I may have been worng about my Z77 max temp I am not exactly sure becuase the intel site says something like 110° for thermal junction. But I am told that you don't want it to get that high. I am just going on what I have already read before so I am sorry about the numbers
