PCCOOLER RZ820 PWM Tuning
It was ridiculous; I bought this massive tower cooler, but while exploring ruins, the fan started screaming like a drill at 1800-2200 RPM per GamePP. I tried changing the fan mode to DC in the BIOS, but the speed became unadjustable and the noise persisted at 50dB per Decibel Meter. I used the GamePP Fan Curve Configuration Panel to micro-adjust the PWM duty cycle around 1800 RPM, starting from 5V. The screeching vanished, and CPU temps stayed at 65-71℃ per AIDA64, allowing me to export
