    What is your cooling method?

    Noctua NH-D15 Dual Radiator Quiet CPU Cooler with two NH-A15 Fans

    Assured as good as an AIO system

    done the 4.8 settings as per the above vid, intelburn is ok, but cpu says 100% usage and only 67'C average temp

    Run prime95, few seconds 90'C and crash.

    Why are they so different?

    well 4.8 on intel burn is ok, 5.0 wont even boot. Put voltage up to 1.32 and still wouldn't boot.

    Happy to stay on 4.8, as its a bit dodge with prime 95. Will try to tweak a bit more and see what I can do

    When I had my 8086k, air cooling wasn’t enough to keep it cool under prime95 (non avx).

    That was 1.325v @ 5ghz. Since I only have a dark rock 4, I keep my 9900k at 4.9ghz at 1.27v to keep the temps in check. You probably need to delid to get temps under control.

    In reality if your temps under your main workloads are fine, then why bother with what one or two benchmarks do to your temps?

    Have you tried disabling hyper threading?

    Don't know much about HT, will that loose me performance in programmes like Lightroom?

    This is just to cool more?

    Indeed, should knock 15-20c off load temps (roughly)

    What vcore are you at for 4.8?

    Use p95 26.6, not later.

    Temps are much higher than my 8700k before I delidded even when at 1.4v at 5ghz. I can probably guess who told you that cooler was as good as an AIO.

    If you get an AIO then just keep the D15 as back up

    p95 26.6 runs much better :D

    hitting about 82/83 on full load. Best not to push further?

    ;)

    Seems all good. You'll need delid to push higher and I'd expect you'll be 4.9@1.4v or less. Worth it? Probably not but all personal choice!

    Probably not much gain over 4.8. Don't want to go down the delidding route. Running at 4.8 should increase Lightroom performance nicely!
