Hi newcomer and welcome to the Tom's hardware forum.
U shouldn't worried, since if that temps was it true ur CPU should be dead right now. Now, u have a good airflow and a good case. What hwmonitor version are u using?
For some reason my reply didn't post. I'm using the newest version 1.16.
I took a snapshot yesterday:
The computer is running fine and it never shows 120C on the icon right bottom. I'm not playing games, just watching movies so the highest temperature I've seen is 45C.
