Nvidia’s RTX 50-series cards have a tendency to run cool and quiet. On average, at least. The current generation of Nvidia GPUs were previously claimed to have had their hotspot sensor removed, which lead to limited temp readings in real-time monitoring tools like GPU-Z, as only the regular GPU and memory temperature data is available.
However, Brazilian modding and repair channel Paulo Gomes claims to have gained access to hotspot measurements on RTX 50-series GPUs via MODS, or Nvidia Modular Diagnostic Software, an internal Nvidia tool that appears to have leaked to some repair channels and Discord servers (via Techpowerup).
By the seems of it, RTX 50-series GPUs do in fact have a hotspot temperature reporting sensor, but it’s disabled at a driver level on boot. The Nvidia MODS tool bypasses the driver restriction, allowing users to see the exact hotspot temperature, making it easier to diagnose a misaligned cooler or improper application of thermal paste.
Which is what Paulo Gomes has been doing in order to diagnose RTX 50-series cards with abnormal gaming performance and high fan noise, due to thermal throttling.
