Why are you telling someone else what there problem “isn’t” after they have already solved it? Flickering is a condition with multiple potential causes. One person could have a bad wire, poor connection, bad fan in the series, defective RGB hub... anything in the current pathway to disrupt the signal. There is no single fix or cause for flickering anymore than failing to boot is always because of component X.

If you think iCUE is the problem, start a new thread with your details in that section. Try a repair install of the program or roll back to the prior version. That should help indicate whether it is a software issue or not.

Here are a few of the common troubleshooting steps you can try to resolve a RGB lighting issue.

Hardware:

1.) Double check all connections to power, USB and RGB data lines.

2.) Be sure you aren't using too many USB devices per USB controller.

3.) If you are using a USB hub connect the device directly to the motherboard USB to test.

4.) Try moving RGB connections on the RGB hub (or Lighting Node Core) to a new port. Only do this when the PC is off. If the Lighting issue persists on the last fan in the chain it's likely the hub, but if the lighting issue gets worse it’s likely the first fan that presents the problem.

Software:

1.) -Close all RGB control and monitoring programs
-Restart iCUE

2.) Check for any firmware updates for your device

3.) -Update iCUE, we add patches and fixes for bugs all of the time.
-Force update firmware of the device if issue persists

4.) -Uninstall iCUE
-Clear your %AppData% folders of Corsair folders
-Install the latest version of iCUE
-Reboot your PC

5.) Check your device manager for any missing or nonworking drivers

If none of those steps work, please reach out to customer support at support.corsair.com and they would be happy to help you.

My LL120's were working perfectly until today. Now it's always doing this annoying flickering thing and I'm sure it's a software issue because when I end the program or service in task manager, the colors sometimes revert or not.

I was thinking it was a software issue, now i'm beginning to believe it's just a fan issue, because once I disconnected all of my fans from the hub, and began to connect them one by one, I was able to narrow down the problem fan, and as long as that one wasn't #1-5, it wouldn't be able to interrupt the rest. I guess I can RMA this one?

Question

Ok can someone explain this -


I re-installed Windows 10 a few weeks ago and ever since that, this has been happening to my fans. I've tried reinstalling software and force updating the firmware on my Commander Pro. My LED strips, water pump and RAM RGB's are behaving perfectly fine. I have changed lighting channels too. My only issue could be the Corsair RGB splitter box that is connected to the Commander Pro has mysteriously broke when re-installing Windows?

Any help would be greatly appreciated.

Thanks,

UnexpectedGreg.

I guess im going to try swapping some fans connections around to troubleshoot this problem too, because ive tried all the other suggestions on the software/firmware side. My whole system is relatively new and I have 6 LL series fans running in my 500D SE case and all of a sudden the 5th and 6th fans just totally tweak out and go crazy if i set them to anything other than a static color. Im guessing that maybe some sort of fault developed in fan 5 and thats causing 6 to display the same weird , buggy behavior with the lightning. The "flickering" im experiencing isnt like what ive seen in most other people's videos, with the occasional bright flicker. The problem seems to be when they try to transition between any colors or patterns. They go beserk, quickly flashing and flickering all sorts colors that theyre not suppose to.

Over the past week, i could have sworn i saw an odd flicker out of the corner of my eye while sitting across the room from my PC. Now tonight I turned on my Pc and those two fans were just going crazy as soon as it started up. Looks like there may be an RMA in my future. Because yeah, these fans are expensive and I havent had them long. Havent gotten to get on my PC much in the last few month either. Been so busy. Finally have some free time to get on here and enjoy, only to discover this headache!
I just recently picked up a shiny new K95 Plat on a great sale too... grr!

Actually, for some reason i didnt see the post @UnexpectedGreg made! Thats pretty much exactly what my two fans are doing! Just going nuts like that.

Looks like I found the culprit! I didn't realize it from the angle i was originally inspecting the lights from, but tonight I really got a good look inside, and discovered that a couple leds on the ring of fan number 4, which was causing fan 5 and 6 to bug out like crazy. I even had a spare lightning node here to test just in case. In both tests, when i swapped no. 4 to the 6th slot, both my no 5 and 6 fan's LEDs behaved normally again! So im pretty positive now that I'll have to RMA this one LL140 fan.

UnexpectedGreg, thanks for your video upload! That's what gave me the idea to perform this trial and error test. For your situation,since all of your fans are displaying the same behavior as 3 of mine were, Its quite possible that your no. 1 slot fan has some LEDS gone bad and they're effecting your entire chain of fans.

Try shutting everything down and swapping around your led connectors on your lighting node, starting with swapping your no 1 fan connector with the last one in your chain. If all the other fans behave normally after that, but the one still bugs out,. Then you've found your culprit!
