How to fix Thermalright PA120 SE thermal spikes in FS25?

When managing a massive farm, my CPU temps were spiking to 92-98℃ instantly, which caused the clock speeds to bounce around like crazy and made the input lag feel like a nightmare. Even though the Thermalright Peerless Assassin has plenty of surface area, the stock stepped fan curve had a massive response lag between 75℃ and 85℃, so the heat just sat there. I tried switching to a Power Saver plan in Windows, which dropped temps by 6℃, but my FPS tanked from 80 down to 45—totally unacceptable. I eventually dove into the BIOS fan control, slashed the fan step-up time from 2.0s down to 0.1s, and cranked the 80℃ trigger point to 1800 RPM. Using HWMonitor, I saw the peak temps flatten out to 76-82℃, and the frame time jitter dropped from 12-30ms to a steady 8-14ms. I did hit a weird resonance noise at first, but dropping the sub-60℃ speed to 800 RPM fixed the humming. CPU power stayed around 115-128W, and everything is rock steady now.
