How to fix micro-stutters when entering bustling towns in Dragon's Dogma 2?

I was so excited to finally enter the bustling town, but the screen started having these maddening micro-stutters. I first tried setting all fans to full speed in the BIOS, but the noise was immense while the core temperature still hovered around 90℃ per AIDA64; this crude intervention clearly didn't work. I enabled the GamePP Fan Curve Configuration Panel, bound the pump speed to the CPU core temperature, and triggered 100% burst mode for radiator fans at 75℃. RTSS monitoring showed frame times converging from 18-45ms to 12-16ms via FrameView, with CPU temperature maintained at 78-84℃ per AIDA64.
