Dont worry about your temps, that CPU wont be burning out from temperatures in your lifetime. I agree with acer0169, dont use auto voltages manually set it. Also what is your room temperature there?
My E6750 clocked to 3.5 @ 1.38v idles around 28-32 and loads to about 50C (room temp is about 70 F). Your CPU cooler is better than mine.
