[New User Help] Corsair rgb fans power cycling every 2-3 seconds (CachyOS/Limine)

Hi everyone!

I am a new CachyOS user, moving my first steps into the Linux world after a lifetime on Windows. I am currently trying to configure my hardware with the help of an AI assistant, but we’ve hit a technical wall that we can’t overcome, so I’m looking for expert advice from the community.

My Build:

  • CPU: AMD Ryzen 7 5700X3D

  • GPU: AMD Radeon RX 7800 XT

  • Motherboard: ASUS ROG Strix B550-F Gaming WiFi

  • Cooler: Corsair iCUE H115i Elite Capellix (with the Commander Core hub).

  • Bootloader: I am using Limine.

The Issue:

On Windows, I use Fan Control and SignalRGB, and everything works perfectly without any conflicts. On CachyOS, here is what’s happening:

  1. ​I initially installed openrgb-git and it worked perfectly: I was able to manage all my LEDs (both Corsair and Lian Li) without any issues.

  2. ​Seeking a way to also control fan and pump speeds, I installed CoolerControl, but the app failed to detect the Corsair hub.

  3. ​I then installed liquidctl. From that moment, a major conflict occurred: the fans connected to the Corsair hub started power cycling (turning off and on) in regular 2-3 second intervals, and I lost control over the device.

  4. ​I noticed that after uninstalling liquidctl, OpenRGB starts working correctly again and the fan loop stops, confirming that the issue arises from trying to have these software/drivers coexist.

My Request:

I would like to be able to control both my fans and RGB stably, just as I do on Windows, but I don’t know how to prevent the software from “fighting” over the USB hub control on Linux. As a beginner, I am not sure how to properly configure permissions, udev rules, or kernel parameters in the Limine bootloader to manage this coexistence safely.

​Could someone provide a step-by-step guide for a newbie on how to stabilize the Commander Core and prevent the fans from looping?

Thank you very much for your help!

Have you tried the app openlinkhub? You can download it in Repo (CachyOS Package Installer).

Hi, thanks for the huge help, I solved it with OpenLinkHub. Liquidictl was the problem, I think it was broken with my core command version.
