I’ve tried everything I can to fix the issue with my Acer Nitro V 15 (ANV15-51-519K) laptop’s GPU fan being stuck at full speed and on the new BIOS version 1.31

Troubleshooting Steps I Have Already Performed:

  1. Reinstalled Software & Drivers:
    • Reinstalled NitroSense fan control software.
    • Reinstalled and updated GPU drivers (NVIDIA).
  2. EC Reset Attempts:
    • Performed soft EC reset (power button hold while unplugged).
    • Performed hard EC reset (battery disconnected and power drained).
  3. BIOS/EC Firmware Update:
    • Updated BIOS to version 1.31, which includes an EC firmware update.
    • Issue persisted after update.
  4. Advanced BIOS Access:
    • Unlocked and accessed the hidden advanced BIOS menu.
    • Reviewed available settings related to thermal/fan/EC configuration.
    • No working options found to adjust or override GPU fan control.
  5. Command Line and Power Settings:
    • Used Command Prompt commands to reset/reconfigure power behavior.
    • Adjusted all related Windows power options and advanced settings.
    • No effect on GPU fan operation.
  6. Third-Party Fan Control:
    • Attempted to use Argus Monitor and HWiNFO to manually override fan behavior.
    • GPU fan not detected or controllable by these tools.
  7. Operating System Isolation:
    • Created two drive partitions and installed Linux on one.
    • GPU fan remains at full speed even on Linux, confirming it’s not OS-related.
  8. Confirmed Behavior:
    • GPU temperatures are normal (~40–50 °C).
    • CPU fan behaves normally and ramps as expected.
    • Issue occurs even in BIOS, before any OS loads.

At this point I am at a complete loss and I don't know how this will be fixed, I'm waiting for another BIOS update hopefully that fixes it.
