Good idea, I had a commander pro on the same ribbon as a SSD, a HDD and my cooler so that easily could have been the issue.

Sadly I just moved both commander pros and lighting node cores onto a separate ribbon and no difference :(

I'm wondering if it's something to do with the internal USB headers/cables. That's what's used to control the RGB via iCUE right? I've bought the NZXT internal USB hub and a male to male internal/external usb cable so going to do some testing later today.

With these being my first RGB fans and having 20 fan cables, 4 hubs and 8 cables coming from those there's a lot of places thing can go wrong. I can see why the new Lian Li uni fans have been so popular, I'd only need 4 fan cables and 1 hub with 3 cables running from it. Hopefully it's something Corsair can replicate!

That should a non-issue. You might pull 5-6W combined from the 3 rails at max write for 1 drive, but that’s not enough to cause issues and an isolated condition that might only appear during a benchmark - not a permanent state.

I don’t understand this issue. Why blue? That’s not what I would expect from a LED malfunction nor a controller crash. Most things don’t default to blue. Is this a very strange software glitch?

i still havent heard from support yet, maybe they can help out or possibly send new fans. i have no idea what could be causing this. i didnt expect having an issue like this with fans of this price.

From BNewt's post theirs worked for a while before turning blue so possibly. Mine have always been like that from initial power on after first installing them before booting into windows.

Because of that I don't think it's a software issue. I'm not sure if the fans have drivers? Updating the hub firmware in iCUE hasn't seemed to help.

I received this from Corsair support.

Quote:
This issue is often caused by 1 or more fans having faulty LED. A fan with faulty LED tends to cause everything further down the chain to also experience issues.

Try hooking up each QL fan to slot 1 on the LED hub. If this doesn't cause any unusual behavior, leave one fan on slot 1 and test the remaining fans on slot 2.

Repeat on further slots until you run out of fans, but always make sure to fill up the slots in order (starting from 1) as they are wired in series. This will help determine which of the fans is faulty.
I've tried reordering fans before with no luck, but I'm going to disconnect all of them and do one at a time and see if I have any luck.

After taking everything out and trying each fan one at a time in slot 1 of both lighting node cores it made no difference. They all lit up with a single blue light when toggling instant lighting on/off with each connection.

I've forwarded this on to support and will see if they come back with anything else.

Would the software then correctly apply colors/patterns once CUE was up and running? Or was it the splattered blue all the time, software running or not?

The fan swap did not work for BNewt either and the the uniform nature across all the fans suggests the problem is with the controller (Core). However, swapping in a new Core did not work either and that is the puzzling part. If there is no change between HW mode and software mode, it suggests the Core controller cannot implement the changes it's supposed to. Both of you see the controller, so we know it's a viable device from a USB standpoint, yet somehow it's still "stuck" on the blue thing. It keeps reading like a bricked/frozen Core device that won't yield control to the software. Yet why did the new Core immediately do the same? Is something in the software putting it into that state?

I'm about out of ideas. One more thing you can try is the following:

1) Quit iCUE. Then navigate to C:Users/(name)/App Data (hidden)/Roaming/Corsair/CUE/hwlightings and then cut and paste that white hwlighting config file to the desktop.

2) Restart the PC. When CUE loads again it will generate a new HW Lightings config based on default values. If no change, you can throw the old config file back in if you like or simply reset your HW lighting (that doesn't work anyway).

I am not overly optimistic, but it seems like something is preventing the controller from picking up where it should. It's possible something in the HW lighting config won't let go.



The other way to address this is to navigate to the same C:Users/(name)/App Data/Roaming folder. Cut and paste the entire Corsair folder to the desktop. Uninstall CUE and check the box to delete all settings. Restart the PC. Before reinstalling CUE, what does the lighting do? Still blue? That does suggest to me the issue is at the controller. Reinstall CUE, see if the lighting changes. If not, you can drop the Corsair folder back into place in the Roaming folder to put all your profiles and settings back into place.

You both might also want to turn on debug logging in the CUE settings. Perhaps there are errors being generated. I am not sure I can read it, but eventually someone is probably going to want it.

Thanks c-attack, I really appreciate the help/suggestions. I agree it feels like a core issue failing to apply the settings to the fans. The fans spin and 1/2 leds light up so it seems unlikely there's issues with them. I'd just be surprised if I have 3/3 broken cores, so again I agree it's more likely software related. I've seen a few people have compatibility issues with asus motherboards, but I'm using a gigabyte board (x570 aorus master).

I've disconnected all my fans from the lighting node cores, disconnected a core so I now have 1 and have connected a single fan to it to simplify testing.

I'm in the process of uninstalling iCUE and will delete the Corsair directory in appdata afterwards (as I'm not using any other corsair software). I'll let you know what happens to the fans after restarting and after reinstalling iCUE. Fingers crossed!

I did an export of the logs a few days ago, I did spot this:
Code:

If this doesn't work I'm happy to share whatever logs might help.

So sadly no change through the entire process. My mouse and ram kept their profiles until iCUE was reinstalled and they changed to rainbow wave.

The only change to the fans was the rpm lowering when ICUE booted up. I've tried connecting a few different fans and they're all the same, although some have a second green led light up

I've attached the logs generated now after reinstalling iCUE

So over the last couple of days I built a new PC out of replaced parts and I installed a clean version of windows 10. I tested a few fans with a couple of the cores and I had exactly the same issues.

I think at this point maybe I've been super unlucky and all the cores are dead. I'm still within the 30 day return period with amazon so I'm going to replace them and see if I have any luck.

The only working theory I have is the software tried to write a hardware lighting profile to the Core, but it somehow was corrupted and stored on the device. The device can't read it and it somehow keeps it stuck in this limbo state. I thought cleaning out the HWLighting config might affect this, but of course it is written to the device itself. If you take a Core and set a HW Lighting of bright pink, then move the Core to a new PC, the fans will come on as bright pink before the software loads. You tried multiple cores and each did this when installed. That makes me wonder if CUE is trying to write a bad pattern to device every time it's connected or if it can't write it at all. This is hardly rock solid evidence, but it's about all I have left. Hopefully Corsair Support can make something of the log info. The flaw in this theory is if your fans were blue from the very first moment they were connected and before iCUE loaded. It could never have interacted with the Core at that point.

If not and you either get new Cores or decide to try again with what you have, I would be really tempted to completely remove CUE and delete the C:Users/name/App Data/Roaming/Corsair folder before installing the new Core. Those are all your profiles and settings, so everything would have to be redone or re-imported.

So I've got the full set of replacement fans, cores and commander pros. I've set them all up and everything works fine.

I tried connected several of the old fans into a new lightning node core and its stuck on the single blue light that it always has been. As I think it's unlikely that all 10 fans arrived damaged, I think it's more likely that the 2 cores I originally used were faulty and somehow damaged all the fans connected to them. Because of this I'm not going to risk connecting one of the working fans to one of the old cores.

So I think the only way to fix it is to replace the fans. I would also replace the core, it might be fine but is more likely the cause of the damaged fans.

I'm going to go back to Corsair support and let them know.

That is interesting. I reached out to someone else to look at this and their take was it's a fan problem. However, I thought that was where each of you started, testing each fan in the #1 slot and none of them worked. I suppose it's possible a bad fan somehow shorted the entire Core controller, like in some type of electrical event. It's still very strange and this not something I've seen before. Other users who have bad fans or blown controllers are usually lights out, frozen mixed patterns of the last known, and not the blue thing.

well, i have been dealing with corsair support for a good week and a half at this point and they are sending me a new core for some reason. not sure why, i told them that i have tried two different cores. i don't particularly want to spend the money on 6 brand new fans, hopefully corsair can send me a replacement set, i doubt it though. at least we know it is an issue with the fans, as i suspected. just odd that every single fan is malfunctioning no matter what slot they are connected to in the core. thank you guys for all the help and im glad pie_masters has his pretty lights back!
