How to stop the PA120 V3 from sounding like a jet in Sims 5?
While building a mansion with hundreds of items, my cooler suddenly started sounding like a helicopter taking off. The default PWM curve on the PA120 V3 is way too aggressive, jumping straight to 100% speed at 65℃, which caused the fans to oscillate between 1200 RPM and 1800 RPM. It was an absolute auditory nightmare. I first tried the 'Silent' preset in the BIOS, but that was a disaster—the noise stopped, but my CPU temps shot up to 95℃ instantly. I ended up manually drawing a stepped fan curve, setting a plateau of 60% speed at 75℃, and optimized the front intake fans for better airflow. My decibel meter showed the noise drop from 45-52dB down to a much calmer 32-35dB, with only a 2℃ increase in temp. I did struggle with the step-up delay at first, which let the temps spike briefly until I dialed the response time back to 0.1 seconds. CPU temps settled at 68-75℃. I switched the mode to 'Custom' in the software, and frame times stayed solid at 5.1-6.4ms.
