Idk mate I’ve got mine at 4.4 with a 360 rad @ 1.33v and I run idle at about 42c. 78c under 100% extended load.
What load, because I have the best 360 rad (all copper block) and my temp's are higher in prime95 8kfft with a 3800x @ 4.4GHz. Also most 3900x won't do higher than 4.2GHz all core overclocks and remain stable.
What stability tests have you run? Have you tried a HEVC load?

For CPU-Z stress test, i'm sitting at 80-85C.
During Adobe Media Encoder 4K x264-x265 very slow with Voukoder plugin (ffmpeg essentially) it's
85-93C. But i have to say that i use manual
4100-4000 1.3V profile for those encoding jobs. PBO would most likely be hotter. FHD encoding jobs, are, on the other hand, sitting at ~70C.
I'm using water temperature to adjust fans RPM and avoid fans spinning up on desktop and light workloads (see
this thread). As for temperatures, those are pretty much what i had on Deepcool 360 AIO.

360 AIO stock 81.5c full load. 4070MHz all cores.

the temp difference betweet the aio and the custom loop is about 1-3C in most tests.
I have a 3900x cooled with an Enermax LiqTech II 360 and when running the AIDA64 stress test for an hour I was right around 83c and all cores at 4ghz.
Mine at wide open is hitting 90c in some benches even with an XSPC waterblock and custom loop.

So I got a 3900x running in a maingear case with the side panels off and i get 81.5 degrees in Hwin64 latest update. Now I am pounding the shit out of it with Keyshot but this does not seem right at all. see pics: and let me add that this prorcessor is Fast as hell. 1800X
