How to tame the Thermalright PA140 fan curve in Deathloop?
The piercing whine of the fans was absolutely destroying my immersion; it's way worse than just seeing a few numbers fluctuate on a screen. The Thermalright PA140 Peerless Assassin has this aggressive ramp-up when the CPU hits 75 - 82℃, sending the RPM from 800 to 1500 almost instantly. I tried the 'Silent' preset in my BIOS, but that was a disaster—my CPU shot up to 92℃ and started thermal throttling. I couldn't sacrifice that much performance. Instead, I went into my monitoring software and mapped a three-stage step curve at 55, 65, and 75℃, adding a 3-second hysteresis to stop the fans from constantly hunting for a speed. In-game, the fans stayed smooth at 1100 - 1300 RPM while the CPU hovered between 72 - 78℃. I actually messed up the first curve by making the gaps too narrow, causing the fans to 'pulse' every few seconds, but widening the window by 5 degrees solved it. VRM temps stayed around 58 - 64℃. A decibel meter confirmed the noise dropped by 12dB. Finally, the noise issue is dead.
