How to fix fan noise jumping in Gears 5 with Noctua NH-D14?

While sneaking in a quiet cover, the fan would suddenly scream with acceleration and then drop, a cycle of speed jumping that was absolutely maddening. I tried the 'Silent' mode in the BIOS, but during high-load combat, temperatures hit 86℃ and the CPU throttled, which was a completely unacceptable extreme. I used the GamePP Fan Curve Configuration Panel to lock speeds below 60℃ at 900 RPM and set a 5-second hysteresis response time. HWInfo64 confirmed CPU temperatures stable at 55-62℃, and RTSS showed frames maintained at 110-120 FPS.
