Tuning Noctua NH-D15 G2 Chromax.Black for Kingdom Come II
Walking through the towns of Bohemia should be flawless with an NH-D15 G2, but I still had these annoying micro-stutters. Monitoring showed that even with a beast of a cooler, the CPU was hitting voltage peaks during load shifts, causing 88-92°C spikes that triggered millisecond-level clock adjustments. I first tried 'High Performance' mode in the BIOS, but power draw shot up to 220W, and the fans kept ramping between 800 and 1500 RPM—the noise was just too distracting. I eventually set a core voltage offset of -0.075V and switched the fan curve to a linear progression. In Cinebench R23, multi-core clocks stayed rock solid at 4.8-5.0GHz with temps pinned at 72-78°C. I actually tried -0.1V first, but the system black-screened during the game loading screen, so -0.075V is the sweet spot. Heatsink fins stayed at 38-42°C. Switched the system to stability mode and temps are now a steady 72-78°C.
