hello sir, thanks for answering to my question, i was emulating ps3 games with rpcs3, for what i know it uses avx instructions, the same that are usually used in some benchmark software if im wrong, correct me please, and i found another problem that was related with my case g21 tg, the problem is that the dusft filter caused an obstruction of the air flow, when i put them off i gain llike 11 c less in temperature, i found about this while watching the review of the case.I agree with the above. Especially the HWinfo64 part. That being said I have a 8700/ msi z370-A Pro in one of my machines. I cooled it with a DeepCool Gammaxx 400. I undervolted to 1.1 vcore, set medium LLC, maxed power limits, and loaded XMP. It passed an hour of prime95 26.6 and 8 hours of realbench no problems. It stayed locked at 4.3ghz the entire time. If I remember correctly my temps peaked in the mid 70's running P95 and and just shy of 70c in RB.
What kind of load were you running to get your numbers?
