I have my 8700k OC'd to 5ghz on 1.27vcore. There is no AVX offset and I have a Noctua NH-D15S. I am running Prime 95 (small fft) right now with 85c on average and 90c max on only one core. Cinebench doesn't get above 73c for example. How long do I need to run prime for, I don't like running the temps so high but want to be stable.
