In WoW cities, my NH-D15 G2 fans keep starting and stopping, causing temp jumps and micro-stutters. Adjust hysteresis?

Idling in Orgrimmar was a nightmare because the fans kept ramping up and down—the noise was just maddening. The Noctua NH-D15 G2 is a beast for cooling, but the default fan response is way too twitchy, causing the CPU temp to bounce between 42℃ and 58℃. These rapid fluctuations were actually causing micro-stutters in the system. I first tried setting a constant fan speed in the BIOS, but then it was too loud during low loads, and I lost that signature Noctua silence, which felt like a waste of a premium cooler. I went into the advanced settings and bumped the fan step-up time from 0.1s to 2.0s and added a 5℃ hysteresis window. In my monitoring software, the temp curve went from a jagged saw-tooth to a smooth wave, staying between 48-54℃. I actually set the lag time too long at first, and when I entered a dungeon, the temp shot up to 80℃ before the fans even noticed—I had to dial it back to 1.5s for the perfect balance. CPU power is around 65-85 Watts, fans at 800-1100 RPM. I've backed up this profile to my motherboard to keep it permanent.
