[SOLVED] How to dectect Nvidia GPU's temperature without nvidia-smi

elight · 2024-11-17 13:22:09

I'm using a laptop with a Nvidia 3060 GPU. I discovered that when I run

nvidia-smi

to get the temperature of my GPU, the GPU will be "waken", resulting in a significant amount of power consumption. I've also tried the same command in Windows and got the same outcome. However, I noticed that the "Task manager" in Windows is able to tell the GPU temperature without "waking" it. So, I'm wondering if there is a similar way in linux to do the same?

How?

I'd check /sys/bus/pci/devices/0000:??:??.0/power/runtime_status and if the GPU is active, seize the opportunity to draw the temperature.
If it falls inactive, check the temperature one last time a couple of seconds (30-60) later and assume that value to be constant until the GPU activates again.
Maybe poll the temp of the inactive GPU at a really low frequency (every 5 minutes or so)

Iff windows ends up doing sth. like that you would probably have not noticed?

You are right, I discovered that Windows only updates its temperature value when nvidia-smi activates the GPU. Thanks for help.
