My DeepCool AK620 fans keep ramping up and down with a piercing whine during map loads. Can I fix this with process priority?

The fans sounded like a miniature helicopter taking off inside my case every time a new map loaded; I honestly thought it was going to blow a hole through my desk. I joked that it wanted to fly me to PlanetSide for real. My first mistake was capping the fans at 1000 RPM, but the CPU hit 92℃ almost instantly and the game started stuttering—a total suicide mission for my hardware. I eventually dug into the BIOS fan step settings and increased the temperature response hysteresis from 0.1s to 2.0s, while smoothing out the curve between 60℃ - 80℃. Using a decibel meter, I saw the peak noise drop from 48dB to 36dB, and that annoying 'revving' sound is gone. I actually accidentally hit 'Full Speed' mode during the process and nearly jumped out of my skin from the roar. Temps now sit between 72℃ - 78℃ with zero performance loss. Exported the fan logs to confirm the logic is finally optimized.
