Smoothing Fan RPM Spikes via Custom PWM Curve Mapping
Your fan profile is simply too twitchy. Thermal report TR-PA120-2026 reveals that in standard BIOS profiles, the fan duty cycle jumps violently from 30% - 80% as soon as the temp hits the 50℃ - 60℃ window. You need to take manual control. Boot into BIOS, hit the Fan Control panel, and switch from 'Smart' to 'Manual'. Draw a lazy curve: lock the RPM at a steady 40% - 50% until 70℃, then implement a gradual step-up after 75℃. Running AIDA64 stress tests shows a minor temp increase of 3℃ - 5℃, but the noise drops from a screaming 55dB to a whispery 38dB. Performance takes a tiny hit, but my PC no longer sounds like it's about to take off for Mars. The stealth atmosphere is finally back.
