[Lenovo Legion Pro 5i 16'' (Gen 8, June 2023) KWCN36WW] Module Loads but FanControl doesn't work

[octave-ati]

Hello,

Thanks a lot for this great module ! I bought the newest Gen8 Lenovo Legion Pro and sadly I am unable to use the fan control features with my setup.
Hopefully it can easily be fixed since it's a new model you have probably not encountered yet !

I am running a Windows / Pop OS Dual Boot with 2 SSDs, the POP OS one is running FDE and the Windows one is unencrypted if it matters !

Problem Descripition
Unable to use the fan control feature with the newest Legion 5i Pro.

The fancurve displays only zeros and I am unable to change it.

The computer also crashed when I tried to change the power mode.

Thanks a lot in advance for any help that you can provide !

I have a very high sensitivity to noise so it is quite disturbing when the PC goes in "jet airplane mode" whenever it has to do some heavy computation, I have bought soundproof panels to try to insulate the noise but this is not perfect and I would love to be able to tweak my fan curve !

Don't hesitate to reach out if you want additional debug info !

It seems like the fancurve can be read (100, 200, ... ) in first column. Unfortunately, in 2023 we can for now only set the custom fan curve in custom mode. This fan curve is only enabled in custom mode. Moreover, the units are fixed yet. So for now 1000 = 100% = max speed.

Can you get describe the exact steps you took to crash it? Did it freeze your whole laptop? Can you get the kernel logs for it. You get them with

# Logs of current session
sudo dmesg
# Logs of last session (before restart/crash)
journalctl -o short-precise -k -b -1

So it is weird because I am currently on custom mode and the modifications I do do not register on the GUI. I am also unable to load and visualize the "premade" profiles. Currently working on getting you the logs !

Edit : Also the logs above were provided while in custom mode

[octave-ati]

Please find the requested log of the crash : log_clean.txt

I don't remember exactly what I was doing, I was mainly fiddling with the options to see if anything produced a meaningful change.

I did not manage to increase my fan speed for example.

I didn't get any error message when the crash happenned, the PC just suddenly shut down. It reminded me of a thermal threshold shut down, so maybe I did actually manage to set the fan speeds to 0.

Any updates? Still the same for me with the newest release

[octave-ati]

Bumping for updates

Sorry did not mean to close

Custom mode for some reason likes to crash on me after a while. Same goes for Windows, the first time it crashes, then after it wakes back from crash it works like fine. But on Linux it just crash and crash for me.
