Fan running non-stop on 20.04 ?

[rgarrigue]

Hi there

I wanted to ask if anyone heard about fan issue running Ubuntu 20.04 ? It installed like a charm, but the fan are running almost non stop. The laptop's hot, the weather not that much, CPU & RAM & disk are doing pretty much nothing... so what the hell ?

Thanks guys !

Did you update from 18.04 or is it a fresh install? I'm on 20.04 fresh install since April and I hadn't have any issues. Sounds like it the nVidia card that is not powering off...
You could check that by running cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status and it should say suspended

My fan keeps running always when I have a USB-C -> Displayport cable connected... Sad... Still looking for solutions )

Same with USB-c -> dock -> hdmi to second monitor
I didn't have this issue with Ubuntu 20.04 upgraded from 19.10, but it's there on fresh 20.04 install.

I have the same issue, fresh install of 20.04 and running setup script. I have a USB-C (thunderbolt) to Dock connected. Running this:

cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status

I get result active
Any advice or fixes?

I had good experiences with smbios-thermal-ctl to reduce the noise, especially when connected to a docking station like wd19tb.

Also see #28

(Somehow connecting to a docking station changed the thermal mode, putting it back to "balanced" or even "quiet" reduced noise quite a lot)
