How to fix Noctua NH-D15S temperature spikes in Phantom Blade Zero?
I couldn't stand it—this top-tier cooler was letting temps bounce between 75°C and 90°C during the beta's high-load sections, making the CPU frequency totally unstable. The NH-D15S is a beast, but the default silent curve is way too slow to react to instant loads, so heat just piles up between the fins. I first tried locking the fans at 100% via software; the noise was fine, but the temps kept jumping, which was just a frustrating waste of time. I eventually went into the BIOS and set a stepped fan curve that triggers full speed at 75°C, and I bumped up the front case intake to feed it more cold air. In side-by-side tests, the temp swing dropped from 15°C to a tight 4°C - 6°C, and the frame rate finally smoothed out. I did notice some slight fan stuttering at low loads after the change, but raising the startup voltage by 0.1V killed that. CPU temps now sit steady at 72°C - 78°C. Comparing the logs, the input response now feels significantly more snappy.
