Summary

  • An Arduino-based watchdog has been designed to prevent Nvidia’s 12V HPWR connector on its 5080 and 500 GPUs from overheating.
  • The 12V HPWR is under scrutiny again as newly shipped GPUs are experiencing thermal issues with the connector.
  • The watchdog uses three thermistors connected to the connector that are calibrated to shut down the PC if any anomalies are detected.
  • Thermistors can be added for more coverage, and the open-source code can be modified as required.
  • The watchdog can be used to safeguard any high-temperature situation, such as 3D printer connectors.
  • Nvidia has yet to solve the overheating issues with the 12V HPWR, which has suffered previous thermal failures.
