Why does TEKKEN 8 stutter during flashy special move animations?

I was devastated when flashy special moves caused my CPU to spike from 62℃ to 88℃ per AIDA64, triggering a frequency drop to 3.2GHz via HWInfo. I first tried setting the fan mode to full speed in the BIOS, but the noise was as piercing as an electric drill, which was totally intolerable. I then used the GamePP Fan Curve Configuration Panel to steepen the speed slope between 75℃-85℃ and reduced the response delay from 2.5 to 0.5 seconds. RTSS monitoring showed frame times converging from 16-35ms to 13-17ms, with temperatures stabilizing at 72-78℃ per AIDA64 and fans at 1200-1400RPM.
