My system crashes during rift jumps in Ratchet & Clank due to thermal throttling on my Thermalright PA140 Assassin, how do I fix this?

I spent a fortune on this rig, and then it just black-screens and reboots during a rift jump—absolutely ridiculous. The default fan curve on the Thermalright PA140 Assassin is way too conservative; it stays at 1100 RPM until 80℃, which let my CPU spike from 65℃ to 98℃ in a single second, triggering the hardware shutdown. I tried setting the fans to 'Full Speed' in BIOS, but the noise was like a jet engine and temps still hovered around 90℃—a total waste of time. I eventually drew a custom stepped PWM curve, forcing the fans to 1800 RPM once it hits 75℃, and swapped to phase-change thermal paste. In AIDA64 stress tests, core temps dropped from 95℃ to a stable 78℃ - 84℃, and the crashes stopped. I had a minor issue where the fans made a clicking noise at low speeds due to low startup voltage, but bumping it by 0.1V fixed it. Noise is around 40dB now. Exported the thermal profile to a backup, and the system is finally stable.
