Countless Issues with LL120 RGB

Ok, so like many others I am having very odd, unpredictable and unstable issues with my Corsair LL120 RGB Fans.

 

About 3 months ago I bought 2 of the 3 pack LL120 fans. I set them up using one of the provided RGB Hubs and one of the provided Lighting Node Pro's with the LED wire connected to slot 1 of the LNP. Everything worked great at first, but slowly I started experiencing intermittent issues where any of the animations would periodically freeze on anywhere from 1 to all of the fans but not any specific fan, completely random which fans would freeze. Later I started experiencing issues where some of the fans would just turn off all-together leaving only 1 fan on. If I set that fan to anything other than a solid color it would work for maybe 3-5 minutes then the animation would freeze. Where my fans are now is that I basically can never get all 6 working at once. Here's what I've tried to troubleshoot:

 

1. First I verified I was running the most current Firmware and iCUE software, I was.

2. Swapping fan LED wires around on the hub. This never results in a "process of elimination" troubleshoot where I can deem any one slot on the hub or any one fan to be at fault. I went so far to number each LED wire from the fans with a number on a piece of tape (1-6). Basically I can get all of the fans to light-up individually and I can even get any/all of the fans to light-up doing 2 at a time in slots 1 and 2 in any order but once I start connecting anywhere between 3-5, a fan that previously would light up no longer works. This has led me to believe that the "passthrough" feature of the fans isn't the issue as all fans are able to do this fine until I connect all 6. So this leads me to the second troubleshooting step.

3. Since I bought 2 x 3 packs I had an extra lighting node pro and fan hub. I Swapped out the ones I had installed for the brand new ones and I get a variation of the same result. Again, there's been no way to identify a hardware issue because "process of elimination" hasn't deemed any of the fans at fault and since I am now using a brand new LNP and Hub it appears to be a software issue of some-kind.

4. Went ahead and bought a completely NEW Commander Pro. Still doesn't work.

5. Tried swapping out the USB header the LNP was connected to on the motherboard. Same result. Also tried using a completely different USB cable that I plugged into the rear IO panel bypassing the USB headers all together. Same issue.

6. Tried several variations of SATA connectors. Putting the LNP and HUB on a single SATA cable that only had 2 connections on it with no other devices on that SATA cable. Tried swapping the order of the LNP and HUB on the Sata chain. Tried splitting the LNP and HUB onto two separate SATA cables that were isolated from eachother and had no other devices on them.

7. Tried rolling back the Firmware version on the LNP to previous versions as other forum posts mentioned this may work.

8. Tried other forum suggestions like stopping the Corsair service from running and then restarting iCue.

9. Did a complete fresh install of Windows 10.

10. I thought maybe it was a power issue so I bought a completely BRAND NEW HX1200 Platinum PSU. Nope, same result.

11. Ended up disconnecting everything from the PSU except the 2 Sata connections for the LNP and HUB. I disconnected the USB from the motherboard and did the reset on the LNP where you power it down, press in the reset button with a pin etc. I figured this SHOULD atleast reset the fans to factory and completely isolate it from iCUE/Windows all together. SAME RESULT.

12. I tried just running 3 of the fans on the hub that I double confirmed putting them in any order on the hub would work. This worked for a bit but then after a restart would go back to only 1 fan lighting up. Or, sometimes when I start iCUE and they're all lit up if I switch to an animation effect like wave they will all work for 2-3 minutes then the animation will freeze or 2 of the fans will turn off all together. In some instances I 1 of the fans will stay lit with only part of the fan animating and 1 or 2 of the other fans partially lit and partially dark, sometimes super dim.

13. I've tried uninstalling all monitoring software and any other RGB software thinking maybe something weird was conflicting.

14. I've undone all cable management and confirmed there's enough slack in the cables. I cannot locate any physical break in the wiring or the fans, hub or LNP anywhere.

 

Overall I'm not sure what is happening with these fans. I've read a dozen or so forum posts with people having similar issues with no resolve. I'm generally frustrated that I spend ~$250 on these fans for the RGB and it doesn't work. I'm thinking there must be some issue with the firmware or iCue that breaks the RGB functionality to the point where even if you disconnect from the motherboard all together they have something stored in memory that is breaking these fans.

 

I hate the idea of pulling these fans out and cutting my losses on the $250 because these are the nicest RGB fans WHEN they work but I've probably put 12 hours of my own time into trying to get them working with no luck. Would love some kind of solution.

 

EDIT: So I just got another Firmware update for the Lighting Node Pro and after the firmware updated suddenly Gigabyte's RGB Fusion software opened. Very strange, I have RGB Fusion installed again but not set to open automatically so I never keep it running but what with iCUE updating the Lighting Node Pro firmware would cause RGB Fusion to open? Very strange, I wonder if there's some firmware conflict between RGB Fusion and the Lighting Node Pro??

Strange, I just replied to someone on Gigabyte's forum with the exact same name: http://forum.gigabyte.us/thread/5504/fusion-interfering-corsair-icue-software

 

 

You did a lot of trouble shooting. Could you do me a favor and go to the LNP/CoPro and click Lighting Setup, Channel that your fans are connected to and verify that your fans are set to 6 fans and not 2?

Hey, yep! That's me as well, RGB issues seem to be my thing lately. Did you see my edit on this post where I mentioned how updating the firmware on the LNP caused Gigabyte's RGB Fusion software to open when it wasn't previously opened? That sort of makes me wonder if my RGB issues on the motherboard are linked to the issues with iCUE/LNP somehow, like the firmwares are conflicting somehow?

 

Anyway, to answer your question; yeah that's like one of the first/basic things I've done. Right now it's actually set to just 3 fans since I disconnected 3 entirely and was trying to just get 3 working first, no luck though.

I have the exact same issue. Same problem description. Same troubleshooting.

 

The status for me right now is that only 2 out of my total 5 LL fans actually give away any light what so ever. Only 50 % of the first fan in the chain actually renders the set lighting effect. The other 50% of the first and the first 75% of the second fan is all disco lights. The last 25% of the second fan on to the rest of the fans are completely turned off.

Very interesting. This is incredibly similar to my experience as well. Out of curiosity what Motherboard are you using?

Have you by any chance played The Division 2? I remember that they loaded custom lighting profiles when I started the game for the first time. Don't know if that's the cause, but it's the only other thing I can think of.

I do not. I mostly play BF5, BO4 and Forza Horizon 4. I typically don't set custom profiles for games but I do know some RGB software will set them by default, for instance Razer Synapse did.

I realised that I haven't actually tried downgrading the LNP like you did. I'm going to have to try that, but it'll have to wait until next weekend for me though. I think I still have my LNP lying around somewhere. *scratches head*

after much troubleshooting... pretty much the same as you (Original poster) minus the purchasing of the comander pro and PSU. I just went into my services and stopped the corsair service, and as soon as I did that, the lights all came on... I only just did this and haven't restarted my PC... lets see how long this lasts *Fingers Crossed*

I've got the same problem. got 8 ll120 fans. and they just started going crazy lately. they worked fine for about 2 or 3 months but now i can hardly control any of them any more. they sometimes wont turn on or off, change color on there own, randomly start blinking,freeze on certain parts of the fan and other stuff. it's a real bummer bcus they really are quite nice when they work. i've also noticed my commander pro sometimes just disconnects for a split second and instantly reconnects. and afterwards it usally messes up the rgb. if i connect them individually they all work fine. hope this will be fixed soon :/.

I was having a very similar issue with my LL fans where they were doing their own rainbow lighting effects ignoring the set lighting as well as flickering on and off. My set up used 2 rgb hubs to control 5 fans and 3 fans which then goes to a commander pro. I've tried everything I can possibly think of with no change except the issue getting worse.

I was fiddling around with the services running on my pc and trying to cut down unnecessary services and to my surprise shutting off all rgb fusion related services fixed the issue. Everything was fine for about a week until i decided to uninstall Gigabyte app center and RGB fusion. Now the problem is back and no matter what I do to undo my actions it won't fix.

Corsair also said to RMA but surely that isn't the only option, something seems to be conflicting with iCue, although i get issues when booting before bios even appears.

Has anyone returned or RMA'd their fans? If so, was it worth it? did they work with the new set? Corsair want me to RMA them, but I seriously don't think its going to be worth it. Plus I don't want to disassemble my custom loop and have no fans on my system for weeks especially if the replacement fans also don't work.

I've got lighting channel 1 set to 4 QL fans, that's the 4 QL fans obv. And then I've got channel 2 set to 2 QL fans which is what I've got the Phanteks strips set to, it doesn't even quite cover all the LED's within the 3 Phanteks strips. Those phanteks tube strips have a lot of LEDs in them. High quality ****, very vivid. Anyhow, with a new Node Pro and new Fan Hub I didn't even plug in the Phanteks strips and I set the channel 1 to 4QL fans for my 4QL fans, but no difference in their dim unvivid color.
