Hotspot temperature sensor on Nvidia's Blackwell gaming GPUs is still accessible if you have access to Nvidia's internal MODS tool — Nvidia RTX 5070 Ti caught throttling at 107°C over poor TIM application

Summary

Nvidia decided to hide the hotspot temperature on its RTX 50 series, but internal diagnostic tools, such as Nvidia's own "MODS," can still read it. The resulting data reveals how some GPUs can overheat and throttle easily, which could be why the sensor was kept hidden in the first place.
