i have a difference in CPU temp only 1 rig. AM says 77°C and Coretemp and AMD Ryzen Master says it have 87°C. CPU is a Ryzen 5 2600x. On other rigs there are no problems (Ryzen 5 1600 temp is right, Ryzen 3 1200 temp is right and on all other Intel CPU´s temp is right)
If you want, please check with the tool OpenHardwareMonitor where you will see the name of many of the CPU temperature sensors and the reported temperature for each of them.
I checked the temperature with OpenHardwareMonitor and it says only 89°C and some lower temps under 70°C and awesomeminer shows 79°C. This is only on the ryzen 5 2600x. Another rig with a ryzen 5 1600 shows 75°C in awesomeminer and 75°C in OpenHardwareMonitor. So there is something wrong.
Could you please also try with the older version called "Open Hardware Monitor 0.8.0 Beta", available here:
https://openhardwaremonitor.org/downloads/
It would be interesting to see if that one reports differently.
Via Open Hardware Monitor you can also export as a report via the menu File -> Save Report. Can you please do this for the Ryzen 2600x system and send me via PM? Please also let me know the temperature you consider is correct for the time you created the report.
The numbers in Awesome Miner is for one of the reported CPU temperatures sensors (so Awesome Miner isn't making up anything here) but it may not be the sensor most relevant for this specific Ryzen CPU. With the report above I might be able to find out the name of the sensors that would make more sense to display.
