Fixing thermal transfer lag on Noctua NH-D15S?
It's honestly a joke that I'm using a top-tier cooler and still seeing frame drops—some kind of high-end irony, I guess. Even though the Noctua NH-D15S is a beast, during sudden load spikes, the heat pipe transfer lag causes core temps to jump 15℃ in 0.5 seconds, leading to frame time swings of 20 - 45ms. I tried maxing out the fan speed in software, but since the noise was already low, it only dropped temps by 1℃, which was just pathetic. I went into the BIOS and enabled a more aggressive step-response mode and carefully redistributed the mounting pressure by micro-adjusting the screws to ensure the base was perfectly flush. In RivaTuner, the frame time graph finally stopped looking like a saw blade and settled into a smooth 12 - 15ms range. I actually over-tightened the screws at first and slightly warped the motherboard, but backing them off half a turn fixed it. CPU temps are now a steady 62 - 68℃. Exported the logs and fan speeds are holding at 1400 - 1600RPM.
