Are These Good Temps For My Overclock?

So I've just done my first overclock and finally got it stable. I have an i7 3770k overclocked to 4.5ghz. I've got my voltage set to 1.28v. I installed a 212 hyper evo last week. It seems this is the best OC I can get, I tried 4.6 up to 1.35v and couldnt stabalize. My case has good ventilation (NZXT phantom 410, 120mm intake in front, 120mm exhaust in back, 140mm exhaust on top). I ran prime95 26.6 for 12 hours, small fft's.

My idle temp are 35-40
100% load are 75-82

Are these pretty good temps or should they be lower? I've never done thermal paste before so was wondering if maybe I should try reapplying to see if I can get lower temps?

For you application, a dab of thermal paste about half the size of a chocolate chip is just about right when placed dead center on the CPU lid. Particular attention should be paid to correctly mounting the heatsink.

Do not move the heatsink around or allow it to move any more than necessary after it's been set and immediately secure the fasteners.

Your temps are within tolerance, but are higher than we like to see. Anything over 70°C is not preferred but I think in this case is largely due only to the cooler as that is a pretty typical result for a 120mm cooler/HSF.

You'll never see those temps or stress levels during normal use anyhow, so I'd say it's good. I might recommend considering a better, larger cooler at some point though...

The Cryorig H5, Noctua NH-U14S, BeQuiet Shadow rock slim and Scythe Mugen 4 are all pretty good coolers, with the Noctua clearly being the best slim single heatsink design out of the bunch.

The Cryorig H5 and BQ Shadow rock slim are much less expensive though, and are still really good performers. Much better than the 212 EVO and are 140mm fan designs besides. Any of these coolers can exchange heat better than the 212 EVO.
