How to eliminate visual artifacts and frame drops during path tracing?

Night battles with path tracing showed severe color bleeding as the PA140 fan speed fluctuated wildly. I tried lowering ray tracing to High, which gained 12 FPS but ruined the visual quality. I then used the GamePP Fan Curve Config to raise the fan speed to 1800 RPM and set startup speed to 800 RPM. RivaTuner monitoring showed frame generation time stabilizing at 11-14ms, while AIDA64 confirmed CPU temperatures held at 68-72℃. This specific fan curve set the foundation for a smooth, artifact-free experience.
