When i play demanding games like bf3 my core 0 temp reaches 71C and when i play the bf4 beta core 0 reaches 83c. I have an i7 3770k but not overclocked. Are these temps too high. I have adequate cooling, do I maybe need to reapply thermal paste? Or is my board maybe screwed in too tight or something? Any help would be appreciated. I idle between 30 and 40 on each core. Also, When the core 0 temp hits 80 the rest stay in the 70's range and speedfan shows the cpu temp at about 69
