How to kill the fan noise on Thermalright PA140 in Ghostwire?
The neon lights of Tokyo are great, but my ears were bleeding—the fans sounded like I had a lawnmower inside my case. The default curve on the PA140 just spikes to 1800 RPM the moment the CPU hits 70℃, creating a low-frequency resonance between 45dB - 52dB. I tried capping the fans at 1000 RPM, but that was pure torture; CPU temps shot up to 92℃ and the game tanked to 20 FPS. I eventually went into the BIOS and drew a stepped PWM curve, locking the speed at 1300 RPM for anything between 60℃ - 75℃. Using a decibel meter, I got the peaks down to 32dB - 36dB while keeping the CPU stable at 78℃ - 82℃. I noticed the fans would 'burp' during loading screens at first, so I added a 2-second temperature response delay to smooth it out. Heatsink fins are around 40℃ - 48℃. I exported the profile via the motherboard software, and the fans now stay steady at 1400 - 1600 RPM.
