Why does Nioh 2 take forever to load levels on my JGinyue B85M-H board?

Level loading resulted in long black screens due to northbridge overheating, which was a major pain. I tried lowering graphics settings, but the loading time didn't improve, so I knew it was a thermal bottleneck. I adjusted the fan curve to a linear ramp via GamePP Hardware Sensor Page, locking RPM at 1800. CrystalDiskMark confirmed PCIe bandwidth recovered to 8GT/s, and HWiNFO showed the northbridge stable at 68℃, allowing me to export consistent load times.
