I just tried to make the switch and sadly went back also. I tried Nobara, PopOS and Mint and while I had little to no issues with gaming, other issues caused me to return. I have Lian Li V2 fans and they won’t work without their Windows or Mac software. If the PC is shut down, they spin at their lowest speed and disappear in my BIOS. Lian Li is more to blame here but I don’t want to replace 3 fans that work fine. I had tons of really weird sleep issues on all 3 distros too. Usually after a fresh reboot, it would sleep as expected but after that, it either wouldn’t sleep at all or immediately wake up. I use WOL to turn the PC on when I want to game in the basement so while a minor gripe, this coupled with my fan issues was so frustrating. I also resisted Linux for a while due to no or little HDR support, but missed it less than I thought I would and I know it’s coming very soon. Loved how lightweight the OS was and miss the simplicity. I shall try again someday…

Thank you. This is great info. I will give this a shot when I can.

Thank you so much for continuing to try and help. It’s greatly appreciated. I am very new to Linux so while I can do some basics, this is very helpful. I installed pyUSB but still get an error when running the script. I have the script placed in my home folder. Should it be elsewhere? The error I get is “No module named ‘usb’. I did adjust the script to have my controller’s proper identification so feels like I’m missing a small piece of the puzzle!

Thank you for the continued effort to help! If I boot into windows and enable the “MB RPM Sync”, the fans are recognized by the BIOS and ramp up and down as needed. This setting does not persist after a shutdown tho. The only way I’ve found to consistently have the fans work as intended after a shutdown is to unplug the USB cable from the Lian Li controller, which kills RGB. I have the PWM connector from the controller going straight into one of the connectors on my mobo. I can tell that after a shutdown, the fans just rotate on their lowest setting, until I open L-Connect 3 again on windows or disconnect the usb port. I’m attempting to implement this: https://github.com/kryzaach/Lian-Li-Unifan-Sync but think I have it placed in the wrong location, as it errors out immediately.

An update: I fiddled with connecting the L-Connect controller to splitters, and a PWM and RGB hub I have and the results are the same: the Lian Li fans are not recognized by the BIOS unless I unplug the USB connection on the Lian Li controller, which kills RGB. When I used the splitter, it actually made my other fans invisible to the BIOS too. Looking closer, I noticed the PWM connector from the Lian Li controller only has 2 pins so I’m assuming it just won’t work without the L-Connect 3 software. Bummer

Thank you so much for the advice but the issue with the Lian Li Uni Fan v2 is that the fan connectors are proprietary and only fit into the controller. The only thing I could split is from the controller and I don’t think that would really change my current situation.

So you were right about one of my SATA connectors on my Lian Li controller being disconnected. I connected that but BIOS still doesn’t see the fans. Then I disconnected the USB connector from the Lian Li controller and my fans were recognized but no LED. I’m going to look into the other suggestion in this post. Thank you for taking the time to try and help!

If I shut down, it sees no fans on that header. If I run L-Connect 3, it shows a single fan’s speed, which is ultimately the controller driving the three fans

I think I did but I will check and get back to you! Thank you thank you!

Thank you for the advice! I tried to run the software in Bottles but while I could run the installer, launching the program threw an error 🤷‍♂️

Thank you so much for the reply! I have an MSI B550 Tomahawk, so a fairly new board. I can definitely relate to the OpenRGB issues as well. I appreciate the offer for your config but I have the lights as stable as they’ll get I think. I just tested again to be sure and when I shut down the system and go to the BIOS, fan 5 isn’t recognized. Right when I log into windows and enable MB Sync in L-Connect 3, the BIOS sees the fans again. I have 2 fans under my GPU and one as exhaust so I’ve noticed higher temps when in Linux. Thank you again for the input. I’ll need to dig around a bit more I suppose.

You are a bold one
