iCUE lightning laggy/stuttering/not working

Recommended Posts


A friend of mine recently purchased a new computer, containing 4x Corsair LL120 RGB LED. I would like to point out that the computer was purchased from a previous user, who had no problems with the lighting of these fans.

So let's cut to the chase, after purchasing the computer my friend asked me to format the system and install the necessary software. Everything went smoothly without any problems. After installing the iCUE software and configuring all the options for the fans in it, it was immediately noticeable that they were acting strangely. At first they didn't all want to light up, then they couldn't synchronize with each other, etc. Since we didn't have much time we figured we'd try to take care of it next time. 

So today we made a second attempt to solve this problem. The strange thing was that 2 of the 4 fans stopped lighting up completely and 1 of the other 2 did not light up fully but sort of half lit up. In the meantime, I read that this error could be fixed by updating the BIOS or reinstalling the chipset drivers. Unfortunately, after applying the above two solutions, neither had any effect. To be sure, we removed the case and checked the connection of all cables and everything looked fine.

I have never configured this type of fan myself and so I am totally without ideas what could be the problem here.

Thanks in advance for any suggestions on how to fix it. 
Below I will give the computer configuration and software version:
- Windows 10 22H2
- Palit GeForce 3090 Gaming Pro OC 24G GDDR6X
- AMD Ryzen 9 5950X
- Kingston FURY 128GB 3200MHz CL16
- NZXT Kraken Z73 3x120
- Corsair LL120 RGB x4 with controller
