According to this Review on the Ryzen 2700X Temperature reading. It has an Offset of 10 degree Centigrade.
But I noticed on the image you Posted that the Tdie (correct temperature reading for the CPU) is 100 C which is overheating.
Already know that and that is between Tctl and Tdie and both are astronomically high. And I am not talking about 10ºC more or less. I am talking about getting 100ºC when the CPU should be more like 50ºC on water @ 1.2V
What BIOS do you have installed? I am confused because there is no version 6101 for your Asus Motherboard unless you have a different Motherboard than the one I linked to.
In the link concerning the Gigabyte Motherboard with overheating 2700X from my previous post, it turned out to be the BIOS causing the issue.
I have the same problem with my 2700X on my MSI X370 Titanium. It
does a thermal shutdown at 100 Celcius under cinebench 15 or RealBench.
I never got such temps under full load on my Ryzen 1800X . I had both
cpus under water with my Alphacool Eisbaer 360 the 1800X never went
above 65 Celcius under stress from Prime 95. There is something wrong
either with the sensors on the chip some thermal issue with the silicon
or else the new bios does not work with the 2700X properly.
I just RMAed the chip. But thanks for your help.
Ryzen Master was showing me the same high temperatures.
If I set everything on Auto my CPU would just simply undervolt/underclock itself to 3.0-3.25Ghz and 0.9V under load to avoid Thermal Shutdown and keep under 95ºC.
CPU was not meeting the requirements for 2700X spec (no even the 3.7Ghz Base spec is met) on BIOS default/Auto so I returned it.
Overclocking, of course, was out of the question with these issues.
I just popped in my old R7 1700 and it never goes above 45-50ºC while overclocked. AiO is fine, cooling is fine, PSU is fine... Everything looks fine except the CPU.
I will bet my bottom dollar that your 2700X was not the culprit but the issue was the bios on your Crosshair VI. My issue which was almost identical to yours was resolved as soon as I installed the 2700X in the MSU X470 Gaming M7 motherboard., completely resolved. I have to believe the upgrade bioses they have issued for X370 motherboards are buggy and are at the heart of this issue.
