Optimizing thermal performance for Gainward RTX 5070 Ti Storm OC
It's honestly ridiculous that a modern GPU can trigger thermal protection just running an emulator. Whenever I pushed 4K rendering, the fans sounded like a jet engine taking off. The default PWM curve on the Gainward RTX 5070 Ti is way too conservative, letting the core jump from 50℃ to a scorching 88-94℃ in a second, which throttled my clocks from 2.5GHz down to 1.8GHz. I tried pinning the fans at 100%, but the noise was unbearable and the temp still hovered around 82℃—complete joke of a solution. I ended up creating a custom stepped curve, setting 80% fan speed to trigger at 65℃ and capping the power limit at 220W. Now, the peaks are locked at 74-80℃ and the frequency stays in a tight 2.1-2.4GHz window. I did have two crashes during the first few boots because my voltage offset was too low, but adding 0.02V fixed it. Core temps now sit comfortably at 68-75℃. Logged all the data via HWInfo to confirm the fix.
