How to display GPU Fan Speed in System Monitor for RTX 50-series?

Hi everyone,

I’m trying to add my GPU (RTX 5080) fan speed to the CachyOS System Monitor, but I can’t find the correct sensor in the list.

What I’ve tried:

  1. I checked nvidia-smi and the fan speed is reporting correctly there.

  2. I can get the raw data via terminal using: nvidia-smi --query-gpu=fan.speed --format=csv,noheader | tr -d ' %'

  3. In System Monitor → Edit Page, searching for “fan”, “gpu”, or “nvml” doesn’t show any active fan RPM or percentage sensors.

My hardware:

  • GPU: NVIDIA RTX 5080

  • Motherboard: MSI MAG X870E TOMAHAWK

  • OS: CachyOS (KDE Plasma)

Is there a way to map this nvidia-smi output directly to a System Monitor widget? Or is there a specific package/plugin (like a ksysguard helper) I need to install to make NVML sensors visible in the new System Monitor?

SOFTWARE/OS VERSIONS
Operating System: CachyOS Linux (Kernel 7.0.10-2-cachyos)

I also opened a case against the development team.

Thanks in advance!
