Hi everybody! I have a question and I think that Software is to blame here.
I have an AMD Ryzen 1600 @ 3.7 Ghz with 1.25v, but I have an issue trying to get the actual temperature of the CPU. The BIOS says that it's about 39º-55ºC (which I think is awesome) and other software (AIDA64, HWMonitor, AMD Ryzen Master) says the same on idle, so it's all good so far, but when I try to run an stress test on my CPU, every software get different temperature at 100% stress.
The most alarming one is the Ryzen Master app, that gets a 78ºC reading in less than 10 minutes, when other apps get temperature reading around 55º-56ºC, so I was wondering, which one should I trust? I have read that there is an offset of 20º in the Ryzen "X" CPU (1600x, 1700x, etc) but this is a "normal" Ryzen 1600. If someone could help me I would really appreciate it (And please excuse me for my English, I'm from Argentina and I actually speak Spanish xD)

System Specs:
CPU: AMD Ryzen 1600 @ 3.7 Ghz
Motherboard: Gigabyte GA AB350 Gaming (BIOS F7a)
RAM: 2x8Gb Corsair Revengeance LED @ 2933 Mhz
OS: Windows 10 64bits

Thank you in advance!
