You have chart in noctua site for thermal performance by cooler.
You will not be sub 70c with stock config. by default 95c is the max temps, so the algorithm is to try to push the frequency with realative high voltage to stay in thermal limits include wattage and current, the temp is side effect, it can rise to 95c. for video editing i am doing manual undervolting with const frequently, so i can control the temps.
If you will get better cooler, you can stay with high temps with higher frequency.
That how it works, its not bad by definition.
Its don't mean you will be in 95c
