Hello! I have recently begun gaming on Nobara Linux and overall, my experience has been quite good. The biggest issue I’ve experienced so far is not being able to control my Lian Li SL V2 fan controller. The fans connected to the controller are only recognized in my BIOS once I run L-Connect 3 in windows but if my system is shut down, they are no longer seen. I have seen this https://github.com/EightB1ts/uni-sync and a plugin for OpenRGB, but keep running into compilation errors and/or lack of maintaining the project. Any advice is very appreciated!
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.
“Fan 5 isn’t recognized”. This confuses me. Wouldn’t your motherboard only recognize the controller? For example I’m using two controllers. My motherboard sees a single cpu fan (the controller with 3 daisy chained fans on one port), and it sees a second chassis fan (the second controller with a 3 pack on one port, another three pack on the second port, and a single fan on the third port).
10 fans, 2 controllers, mobo only sees 2 “fans”. Here’s a video showing exactly how I wired mine up, and the type of fans and controllers (maybe we don’t have the same parts).

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
Ah I see, #5 is just the header you’re using. You aren’t using 5 total. That makes more sense.
I don’t even have L-connect installed, but I did once upon a time. Maybe I changed a setting there and forgot about it, but I don’t think so. Either way it’s probably worth checking that your bios is set to “PWM” for that header, and that L-connect is set to “enable MB PWM Sync” under the fan/pump profile page. (Just from googling). Look for settings to turn off any L-connect interaction - forcing it to pay attention to the fan header?
I’m wondering if your controller is somehow set to ignore the header pins and run from just the usb port/L-connect. And maybe on a power cycle, your mobo thinks there’s no fan?
I dunno - I’m shooting in the dark now though. All I know is that my controller always shows up as a single fan, and all the attached fans run at the same speed - whatever the header calls for. No software installed, all wired connections are made, exhibits this same behavior regardless of OS, power cycles, reboots, etc.
Sorry I’m not more help - it’s frustrating when things that should “just work” don’t.
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!
Oh! Did you plug in BOTH SATA connectors? I think one is for rgb and the other is for fan speed. Maybe that’s screwing things up?
I think I did but I will check and get back to you! Thank you thank you!
