Hi everyone, I know that there is a lot q/a for this topic but I just can't find an answer.
The problem is with my AMD ryzen 1600x, teperature (even in idle) jumps for almost 10 C, constantly...lastest bios is fleshed, and really important thing is that I have NOCTUA NH12 (am4 edition) !
Temps are from 30/35 to 40/45 C. Seriously I dont understand what could be the problem.

MB Asus B350 prime plus
PSU EVGA super nova G3 650W

Thants a lot for answers
