I recently upgraded to the AMD R7 2700X CPU and it seems that Speccy Pro 1.32.740 is reading the CPU temp at 60C higher.
Confirmed this against AMD Ryzen Master, Core Temp 1.12.1, and HWInfo, all three show the CPU temp running 60C lower.
This is a new Windows 10 install, ver 1803, with all updates/drivers applied. I just noticed the program is reporting the CPU as Summit Ridge when it's a Pinnacle Ridge chip.
Here's a comparison:
Not sure if it will help, I've attached a Register dump from Core Temp.
