Stopping the frame drops on Manli Snow Fox RTX 5080 OC?

Every time I enter a dense fog area, my FPS craters from 120 down to 55, which is incredibly frustrating. The GDDR7 memory on the Manli Snow Fox RTX 5080 OC runs scorching hot, hitting 95-102℃ after about 15 minutes, which triggers a forced core downclock. I tried dropping the resolution to 2K, but the image looked blurry and the temps stayed above 90℃—that whole experiment was just a waste of time. I ended up using MSI Afterburner to set a core voltage offset of -0.05V and cranked the fan curve to 85% once it hits 70℃. Using RTSS, I saw the frame times tighten up from a wild 12-35ms swing to a steady 8-12ms. I actually hit two driver crashes immediately after undervolting, but lowering the core clock by another 30MHz fixed it. Core temps now sit at 68-74℃ and VRAM dropped to 82-88℃. It's finally playable without the annoying dips.
