Overclocked to 4.5 on 3570k, need to know if my results are normal/okay.

I did a stress test for 15 minutes, the highest temperature was 89 degrees(100% load) but I don't know whether this is normal? I have got the Freezer 7 PRO Rev. 2 cooler, on 80% all the time (1400-1600rpm) and it idles between 20-35. Any answers would be appreciated, thank you.

If a core fails on Prime95, the OC is unstable. Temps look normal, though.
