Noticed this temperature after the expiration of the warranty. Most likely this temperature was from the time of purchase.
Without having a screenshot from Ryzen Master, we can't tell you if it's right or not, since we don't know if it's measuring the proper sensor, or compensating for the 20*C offset.
Sorry but I use Linux and don't have an opportunity install Windows to use Ryzen Master.
linux will alert you if there is a problem
Something like this?
looks like the CPU is working within the kernel expectations
