Nvidia Blackwell GPUs Found to Throttle at 107°C

WireByte Staff · July 11, 2026

Nvidia's Blackwell gaming GPUs, including the RTX 5070 Ti, have a hidden hotspot temperature sensor that can be accessed with Nvidia's internal MODS tool. Testing revealed the sensor reports temperatures up to 107°C, despite standard diagnostics showing normal temperatures. This finding has implications for users and repair shops, who may need to use specialized tools to diagnose overheating issues.

Key points

  • Nvidia's Blackwell gaming GPUs, including the RTX 5070 Ti, have a hidden hotspot temperature sensor.
  • The sensor reports temperatures up to 107°C, despite standard diagnostics showing normal temperatures.
  • The sensor can be accessed with Nvidia's internal MODS tool, which is not available to the public.

Nvidia's Blackwell gaming GPUs, including the RTX 5070 Ti, have been found to have a hidden hotspot temperature sensor. This sensor can be accessed with Nvidia's internal MODS tool, which is not available to the public. Testing revealed the sensor reports temperatures up to 107°C, despite standard diagnostics showing normal temperatures.

This finding has implications for users and repair shops, who may need to use specialized tools to diagnose overheating issues. The issue has been confirmed on a Gigabyte variant of the RTX 5070 Ti, which was sent to a Brazilian repair specialist due to overheating issues.

The MODS tool is used to test GPUs before they hit the shelves or during the RMA process. It's not available to the public and doesn't work on Windows because the OS keeps intercepting calls from the hardware monitoring APIs. Repair shops and users may need to use a Linux distribution that boots directly into a command line to access the MODS tool and diagnose overheating issues.
