I upgraded from an RX 6800 to a Zotac RTX 5070 Ti in a small-form-factor build. With the AMD card, I could raise the zero-RPM threshold from 55°C to 62°C and cap lighter games at around 72 FPS, which kept the system effectively silent whenever the GPU stayed cool.
The 5070 Ti starts its fans at roughly 30% around 50°C, even in games such as Terraria, Hollow Knight, or Monster Hunter World when they are capped at 60–80 FPS. Since the GPU stays below about 60°C, I would prefer to let it run passively instead of adding unnecessary noise and dust. Is there any software, firmware, or BIOS method to change the zero-RPM temperature or minimum fan-speed limits on this card?

Running the fans at 30% is not harmful to the GPU, and temperatures in the 60–75°C range are perfectly normal. However, your goal is reasonable: if the fans are noticeably loud while the GPU is cool, passive operation would reduce noise and avoid constantly spinning the fans. If the card repeatedly starts and stops its fans at idle, improving airflow around the GPU with a quiet case or auxiliary fan may keep it below the trigger temperature, though that will not change the built-in threshold.
Nvidia cards tend to enforce the minimum fan speed and zero-RPM behavior more strictly than many AMD cards. Tools can usually adjust the fan curve above the minimum, but they often cannot remove the firmware-defined 30% floor or change the temperature at which the fans start.
Unfortunately, this is generally controlled by the card's VBIOS rather than normal tuning software. A modified or compatible VBIOS might change the fan behavior, but flashing one is risky, especially if the card lacks dual BIOS support. BIOS files also usually cannot be transferred safely between different brands or models.
That makes sense. I was hoping there was a less risky way to change it because the GPU stays under 60°C in the lighter games I play.
There is no overheating problem here. I mainly want zero-RPM operation during low-demand games because the GPU remains below 60°C, so the fan noise feels unnecessary.
