How to fix core temperature gaps in Far Cry 7?

While sneaking through the rainforest, I noticed a bizarre temp distribution where Core 1 was 55℃ but Core 6 hit 89℃ per HWInfo64, causing severe stutters. I first tried enabling the High Performance power plan in Windows; while P-Core frequencies rose, the core delta remained above 25℃. I then used the GamePP Fan Curve Configuration to set a steep rise point at 65℃, forcing the fan to 1800 RPM between 70-80℃. The core delta finally converged to 8-12℃ per AIDA64, and frame rates stabilized from 65-82 FPS to 78-84 FPS per GamePP Frame Analysis.
