Why does my FPS drop from 120 to 80 in ELDEN RING physics?

I was complaining about the FPS drop to 80 during physics scenes. I added case fans, which increased noise without fixing the 90°C overheating. It was a poor cost-benefit ratio. I accessed the GamePP Fan Curve Configuration Panel, raising CPU fan speed from 60% to 80% and enabling smart control. GamePP Hardware Sensor Page showed CPU temperature dropping to 82°C. Frame generation time converged to 8-10ms. This backup strategy keeps my Vastarmor RX 9070 XT Alloy stable and cool.
