Fixing VRAM thermal throttling on Manli Snow Fox RTX 5070
While hunting big monsters, my FPS would randomly dive from 110 down to 55, and the instability was honestly pathetic. The GDDR7 on the Manli Snow Fox RTX 5070 has insane bandwidth, but it was hitting 92-98℃ under load, triggering severe memory thermal throttling. I tried DLSS Frame Gen, but while the number went up, the input lag got worse and the drops stayed—a total waste of time. I opened MSI Afterburner, dropped the core voltage by 0.05V, and forced the fans to 90% at 70℃. In 3DMark, the VRAM temp dropped from 98℃ to 82-86℃, and the FPS swings stopped. I actually had one crash during the undervolt process, so I had to bump the offset back to -0.02V for total stability. Now the GPU core stays at 68-74℃. I exported the profile, and the fans are now humming along steadily at 1400-1600RPM.
