Hi
I've got a reasonably common setup: i7 5820k with an H100i (x99a motherboard)
With a vCore of 1.29 (just under the "sensible" limit as far as I can tell? And well below the 1.35 limit most people seem happy with) and a multiplier of 45 I'm running at 4.5GHz - my target, although naturally I wouldn't turn down higher. It boots fine (test 1) and I'm not necessarily looking for perfect stress test stability - as long as it can stay alive when I'm playing FSX, I don't care.
When running Prime95, though, the temperature rockets. I see 100c fairly quickly and then I shut it off: I was expecting more like 80c with stability being the issue if I tried to push it any higher! Not 100c and not giving it the chance to prove it's stable
Temperatures at (mostly) idle are 25-30c, and around 60c at stock clock under Prime95 load. Does this seem a little high?
My first guess is that I've messed up the cooler installation - I did it well once and then got misled by a fan controller doing 5 beeps and making me think the CPU had a problem, so I re-seated it and it's possible I didn't do as good a job with the thermal paste etc the second time.
Any other thoughts? Could I just have a chip that's not going to be happy at 4.5 with an H100i GTX?
I'll try re-seating again tomorrow and re-trying with a lower vCore to see where I end up, but any thoughts appreciated
