I’m trying to find out what temperatures you get, please, when running Prime95 small set. I'm especially interested in results at all core turbo (all cores at 4.3 GHz) and AVX offsets of 5 (which puts AVX instructions at 3.8 GHz).

    Not able to switch my OC to your specs since I don't have time to do the testing and re-test going back to my settings, but I'll show you what I get at mine:

    Thank you! That is very interesting. You got lower temperatures than me with 10900X even though my clock is lower (I'm at 4.3 GHz with offsets of 3/5). I'm wondering what is exact reason for difference, does it have anything to do with my settings or fact that your fans were at 100% and my fans were controlled by default CLC360 profile. I'm guessing it is most likely later but I should be able to easily check that, I need to do some work on case fans anyway.
     
    What I am really trying to find out is does 10920X run hotter than 10900X at same setting and, if yes, how much so I can decide can I get 10920X for my second rig or should I stick with 10900X. Have you come across any data that compares temperatures between two?

    Try it with Rad Fans and Pump at 100%, I never push my system hard unless I do that.  Otherwise I have a custom fan curve that starts low and ramps as the CPU heats up, pump is set to Balanced (~2100RPM).   Right now rad fans are ~700RPM with a CPU package temp of 36C.  The case is a Fractal Define R6 and I open the front door too so I have the best intake.  I do leave the dust filter on, but I make sure it's clear before I benchmark and test a new OC since I've seen as much as a 10C drop if it's a bit clogged after cleaning if I forget.  The other fans running at 100% other than the rad ones are 3x120 on top pushing air out, a 140 in the back pushing air out, and a 140 on the bottom pushing air in.
     
    Mostly same settings I found online, the 12 core always ran hotter since I had to push a higher voltage vs. the 10 core to keep it stable.  Other than that I really can't say about the 10900x since this is my first X series CPU.  I prefer to keep my temps as low as possible so that's why I'm at 4.6, I wasn't happy with 4.8 or even 4.7 pushing into the mid to high 80's in R20.  I tried copying some numbers I found from a 10900x 4.8 OC back in Jan. and in order to keep the system stable I had to push the VCORE higher than I wanted even after dropping it as low as I could until I crashed.  There's no real world difference in 4.6 over 4.7 so I'm happy with how I have things set now.  I might be able to fine tune a higher clock, but at summer the room it's in can reach the mid 80's (F) so I'd have to drop it again anyway.
