Question

Iron

Hello, is this cpu temperature graph normal without load?

CPU: Ryzen 5 3600 -- https://www.amd.com/ru/products/cpu/amd-ryzen-5-3600
Cooler: be quiet pure rock slim -- https://www.bequiet.com/ru /cpucooler/688

Answer 1

Absolutely.
It's just that the program reads the readings crookedly (it takes not an average indicator, but an instantaneous one).

Answer 2

Hello.
According to the graph, the temperature jumps from 42 to 60 degrees. The graph jumps due to the fact that the background functions of the OS and some programs are running.
