Fix Valkyrie V240 LOKI Whine
It was ridiculous; my advanced AIO sounded like a power drill while I was exploring England. I tried changing the pump header to DC mode in BIOS, but the speed became unadjustable and the noise stayed, which felt totally ironic. I used the GamePP Fan Curve Configuration to adjust the PWM duty cycle around the 3000 RPM resonance point, setting a start voltage of 7V. The metallic whine vanished instantly. GamePP sensors confirmed CPU temperatures remained stable at 64-70℃, and the noise dropped from 55dB to a low hum.
