I agree with Daniel. Your temp and voltage looks fine... Now, if it were me, I would dial back the OC a hair and see if you could drop the voltage a lot for the longevity of the chip. It would make no noticeable difference in how the system performs, but might make a huge difference in the temps...
For example, my own chip (6700k) does 4.6 at 1.25v (65), 4.8 at 1.32v (lower 70ish), and 5.0 at 1.43 (mid 80ish). I choose to run mine at 4.6 for day to day stuff and only turn up the juice for benchmarking.
Your settings are fine and may never affect your chip... But I have always thought of it like a car. If you drive your car peddle to the mettle all the time, you are going to wear things out faster...
Good Luck,
Adam
