My Alan Wake 2 keeps dropping frames in heavy lighting scenes with the RT500 TC ARGB. Why?

Whenever I hit those psychological horror scenes in the dark forest, my CPU temps would rocket to 98℃, and my FPS would tank from 85 down to 32. It was a total nightmare. The default fan curve on the PCCOOLER RT500 TC ARGB is way too lazy, only ramping up after 70℃, which is just too late. I tried blasting the fans at full speed in BIOS, but the noise was like a jet engine taking off in my room, making the game unplayable. I ended up manually mapping a stepped response curve, setting 60℃ as the trigger for 70% speed, and swapped my thermal paste for a high-conductivity compound. Checking HWMonitor, my core temps are now locked between 82℃ - 86℃, and frame times tightened up from a messy 15-40ms to a rock steady 11-14ms. I did have a moment where the fans were hunting—jumping between 1200 and 2000 RPM—until I bumped the smoothing delay to 0.5 seconds. CPU power is hovering around 140W now, and the exported profile keeps my frame times at a crisp 11-14ms.
