Not sure why you are resorting to yelling at the OP and telling him how wrong they are?
He is referring to the fact that the number that he thought was the actual temp in hardware info was really the thermal limit number. The actual temps are on a status page in HWInfo. It can be a confusing app to navigate.
Then his reference to PTC is shown at the top right of "Ryzen Master" as he already posted the picture of above, exactly the app you suggested he use. PTC is the point at which Ryzen Master says the processor will throttle when that temperature is reached. That max temp is 68c as shown on the AMD spec page: https://www.amd.com/en/products/cpu/amd-ryzen-threadripper-2950x
Has me a bit worried though as this by AMD's specs in Ryzen Master is too high. My guess is that this number is derived from a database not actual temps in any way. Since the thermal limit of this Threadripper CPU is much lower than that so must be the throttle point. So maybe a flaw in Ryzen Master?
You are correct about about many 3rd party apps having a difference in the way they report the temp. On average though, they show the same temp.
Many of the 3rd party apps poll the cpu at much more frequent intervals and freaks some users out not knowing why the temp is jumping all over the place.
Ryzen Master sees the same thing it just doesn't report it in real time as to not give all the sporadic reading and gives more of an average. Neither is necessarily wrong. Regardless it is good to have another app to run as a double check if you think something may be wrong. Additional ways to validate are typically a good thing. I for one leave core temp running all the time and have no issues with it whatsoever. When I launch Ryzen Master the numbers are always in line with core temp.
Just like when Zen 2 came out Zen 3 may require updates again to be compatible and give accurate reads. Obviously 3rd party apps will likely not be on parity with what an official app from the manufacturer may provide. In the case of core temp though, it's feature set is not only used by it's own app but integrates into several other utilities that many users find very helpful. Using them doesn't make anyone wrong. It's always smart to validate against the standard in this case Ryzen Master.
Thanks I was typing a reply at the same time.
Ryzen Master in this case concerns me though as it is not reporting the correct PTC for that processor as the max temp is 68c for that processor.
Must be a bug or the OP has an older version installed.
The PTC that Ryzen Master is showing is for 3rd generation processors and not 2nd generation processors.
Thanks for verifying that Core Temp has similar temperatures as Ryzen Master. I use Core Temp for my Desktop CPU Gadget to keep me aware if my FX8350 is overheating unexpectedly. That was how I was able to find out my old CPU Cooler wasn't working the way it should and made me upgrade to a more powerful CPU Cooler.
I still run gadgets too. In addition to seeing the temps I can set alarms as well with the gadget that will go off if thermal limits are reached.
A guy named Igor maintains a large library of great monitor gadgets that are resizeable and you can set the resolution so they look good too at modern desktop resolutions.
Here are the links if you would like to try them. His page is about impossible to find through search although his gadgets are also downloadable through many other places.

I highly recommend System Monitor II and it uses core temp.
I also like his GPU Monitor although a couple features don't work with current gen cards.

That is the same place I got my gadgets. I also have those gadgets on my desktop. Really useful.
I used 8gadgets to install the gadgets in Windows 10.
