Converted... R7 3800x incoming!

I run it at auto/stock and I'm using it mostly for reviews and other tests. When I make memory OC comparison then I always keep it at stock so it will be repeatable also for readers.
I'm using almost only air cooling for tests nowadays so I'm quite limited. I can overclock the CPU as long as I'm not bumping the voltage but for 3900X it's not really an overclock.
Even better air cooling is giving me 90°C+ under full load on the 3900X. The best results were on Noctua NH-D15 chromax.black but it's too big for my current motherboard and I have to use NH-U12S. 3900X temps should be around 6-7°C higher than the 3600X/3700X/3800X.
In my tests 6 and 8 cores heat up about the same. Noctua engineers confirmed that too. It's a matter of die design. I think if you are using Corsair AIO for your CPU then you didn't try something like Prime95 with AVX or AIDA64 FPU+CPU tests. I wasn't able to go under ~77°C on a pretty good AIO and 3700X under full load. The best results on air were at low 80's like 81-82°C.
Check temps using hwinfo64. It seems to be the most accurate. Max temps are up to 95°C so anything under that is still good and without throttling

My basement is cool right now in the 60F range so yeah I top around 68-70C right now. Weather its the 1.25V i'm tossing at it right now or the 1.3V i toss at it for 4.3Ghz at least. I seen it go up to 72-73C on an unstable 4.4Ghz clock with 1.35V. Overall I've been impressed with my AIO after got the contact situation fixed on my Intel block. Curious if maybe I could improve this with a few washers for a little extra force. It improved my temps, and quieter since I run the fans either at "quiet" or "balanced mode" (half speed) and it does a fantastic job for RGB Corsair fans.


Actually tried the Intel Burn Test this morning (what I used for stability before) and hits roughly the same temps as when I encode. Hit 69C, and the highest temp on the board I saw was 93-95C for some component that typically was in the 88-89C range. Was going to try the AIDA64 next just didn't have time this morning to run it so I'll post results of that in the next day or two.
