My Noctua NH-D15 G2 can't handle the sudden heat spikes in Frostpunk 2, causing massive clock drops.

While managing New London during a brutal winter night, my CPU load suddenly spiked to 98%, and the Noctua NH-D15 G2 core temps were jumping wildly between 82-88℃, causing my frame rate to tank from 75 FPS down to 42 FPS. It was honestly baffling; I'm using a top-tier dual-tower cooler, yet I was hitting thermal throttling during large-scale city simulations. At first, I tried slamming the fan policy to full speed in the BIOS, but that only dropped temps by 4℃ while making the rig sound like a jet engine at 40dB without actually fixing the stutters. I then used HWiNFO to analyze the heat soak curves and realized there was a dead zone in the airflow between my front intake fans and the cooler. By setting a non-linear stepped ramp for the fan curve between 65-75℃ and bumping the rear exhaust voltage to 1.35V, core temps finally stabilized in the 72-76℃ range. I actually messed up during the process and accidentally set the fans to silent mode, which let the CPU hit the 95℃ wall in under 3 minutes before I recalibrated the offset. After a final stress test, the frequency fluctuations narrowed from 120-4.2GHz down to a steady 4.8-5.0GHz with fans humming at 1400-1600RPM. It's a bit of a hassle to tune, but it works.
