Fan control in Lenovo Yoga Slim 7i 13ITL5

Support
1

I’ve got a computer as in the title with up to date Manjaro and I can’t get access to the fan speeds, something I’d like to do in my quest to make this computer be quieter.

Ran sensors-detect; sensors doesn’t see any fans (below: fan speeds N/A). NBFC doesn’t have my model. So I’m at a loss as to how to get access to that. Chip: intel i5 1135-g7.

Thanks!

did you run “sensors” first to detect suitable sensors ? I don’t think so. Please run this first to create a config with the sensors. Follow the instrutions of the link below:
https://wiki.archlinux.org/title/Sensors

enable the aur-packages from the packet-manager and search if there are suitable apps for “lenovo”.
for example “lenovo-ice…”. if your bios is able to use this tool try it.
also check for “linux-firmware” updates at the packet-manager.

i’m not shure if “nbfc” is the right tool, you can try it or search for fancontrol in the packet-manager.
the basic for everything is to run “sensors” first for the sensor-detect procedure.
it might not be the ultimate solution but it will be a step forward with your problem.

I had run sensors. Below is the current output.

I installed lenovo-ice…, rebooted as required, but sensors is still not seeing the fans. linux-firmware is up-to-date.

may you run the inxi command again and post the new output ?

disable and unmask it before going on. there can’t be a effect if this is still active

Used the commands below. Sensors and inxi show the same re: fans.

EDIT: FWIW I didn’t set nbfc up as after installing it I realized it had no preset for my machine, so I might as well uninstall it.

systemctl disable nbfc.service                                                          
Removed "/etc/systemd/system/multi-user.target.wants/nbfc.service".

  ~ systemctl unmask nbfc.service

I haven’t yet managed to solve this, the issue is still open. If I ever solve it, I’ll come back.
