Options for Lian Li Fan Control

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 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!

Shot in the dark, but does running the Windows software in Wine work?

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 🤷‍♂️

Hmmm…. I’ve got those exact fans and the controller that comes with them - 10 fans to be specific, and they really haven’t given me any trouble at all. There are three sets of 3 daisy chained, and one single fan. They connect to a relatively new asus board. I’m running arch and openrgb from the aur.

The fans doing fan things (spinning), that just works. They ramp up and down based on the case fan connector from the mobo. One three pack is on the radiator to an aio cooler and that triplet ramps up and down based on the fan speed header for the cpu.

The LIGHTS are a different story. If I cycle power completely, they do the default rainbow puke when started back up. OpenRGB required a little configuration and playing around to get the number of lights correct, and synching properly-but it worked. (I can get you my settings in openRGB if that helps avoid the trial and error). Because my mobo still supplies power when I power down, the lights hold their last pattern when I reboot.

So in my experience-those fans spin without any software and light up at least rainbow puke without any software. You only need software to get different colors or to just override the fan header and set a manual speed.

I’m wondering what your computer/mobo is doing to stop that. Weird.

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).

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?

gazoinksboe OP ,

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

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
