Fixing the 'silent' thermal throttling on Noctua NH-D15 G2 in Metaphor?
It's honestly a joke that a top-tier cooler like this could cause stuttering. The default silent curve on the Noctua NH-D15 G2 is way too conservative. When the CPU spikes in power, there's a 3-second lag for the fans to ramp from 400 to 1200 RPM, causing the core temp to jump 20℃ instantly and trigger a brief frequency dip. I tried using the 'Ultimate Performance' power plan to force it, but that just added 10W to my idle power draw without fixing the stutters. Total waste of time. I went into the BIOS and slashed the fan response time from 0.7s down to 0.1s, and set the 60℃ trigger point to 1000 RPM. In my frametime analyzer, the 1% lows jumped from 30 to 55 FPS, and it finally stopped feeling like a slideshow. The fans were revving up and down like crazy at first, but I smoothed out the curve to kill the noise. Now temps are a chilly 60-68℃ and fans stay steady at 1400-1600 RPM. I've exported the logs to make sure this sticks.
