Most likely 3 issues.
-Location restricting airflow
-needs to be cleaned out
-thermal paste is old and needs to be replaced
One more thing. The settings for temperature are adjustable. I would not adjust them outside what the reccomendation is but verify they are not set lower than the recommendation.
I recently changed the paste, but I was thinking maybe it's not a good kind. Cause it was no name lol. So I'm ordering artic silver 5. And see what happens. Also when I changed paste I cleaned it as well.
Since there was a new update for my GTA v menu, it's been doing this. When I use another menu it's fine, will not shut off with warnings but still runs very hot. But with the new update menu it gives warnings and shuts off.
