My NH-D15 G2 is reacting too slowly during massive base renders in Ark 2, causing CPU throttling. How do I fix this?

The silence of this cooler is legendary, but the response time under extreme load is a joke. While rendering complex terrain, my CPU would jump from 65℃ to 92℃, and my clocks would crash from 5.2GHz to 3.1GHz. It's a nightmare for productivity. The default Noctua curve barely hits 800 RPM until 80℃. I tried the High Performance power plan, but that just accelerated the heat build-up, making the thermal wall hit even harder. I eventually manually set the PWM curve to 1500 RPM at 75℃ and flipped the fan orientation to a more aggressive push-pull exhaust. AIDA64 stress tests showed peaks dropping from 94℃ to 76-82℃. The noise increased, obviously, but I balanced it by dropping the sub-60℃ speed to 600 RPM. Now the CPU load is a steady 70%, and the system feels responsive again, though the fan hum is a constant reminder of the struggle.
