Temp problem with multiple GPU setup

Bug

Summary

Environment

  • CoolerControl version: 0.15.0
  • Installation method: deb
  • Distribution name and version: Ubuntu 22.04.2 LTS
  • Desktop: KDE
  • Cooling device model(s): Corsair h150i rgb pro xt
  • GPU Nvidia RTX 4090 FE
  • nvidia-driver-525 (proprietary)
  • NVIDIA-SMI 525.105.17 Driver Version: 525.105.17 CUDA Version: 12.0

Steps to reproduce

  1. step 1: run luxmark benchmark
  2. step 2: monitor GPU temp in CoolerControl and nvidia-smi
  3. step 3: while nvidia temperature rise up the one that coolercontrol reads stays stable!

NB: The custom speed profile is controlled by the GPU Temperature of the Nvidia GPU.

As you can see from the screenshot:

  • while the GPU temp in CoolerControl stays below 25 degree
  • the nvidia-smi tool read a temperature of 36 degree in one case and 52 degree in the other screen shot

I'm not an expert but isn't it a potential risk ? Because GPU fans do not spin faster (stays at 30% selected by a custom speed profile). Is there something I have to do to better setup my system? Thanks - CoolerControl is super!
