Issue with Corsair fans not being detected by HUB in iCUE - Fans work, but no RGB effects

quote:

---

Are you overloading the fan outputs on your motherboard by chance? Sometimes when you put 2-3 or more fans on a motherboard fan pin out or RGB pin out the power consumption is too much for the motherboard especially during startup.

Honestly, have no idea...I don't think so? I used CyberPowerPC to build the PC, so I'm not really familiar with PC hardware and how everything works. Not a great idea, I know, I've just never delved into it. Each set of 3 fans came with an individual hub, so I'm assuming power isn't an issue. I've contacted Corsair & CyberPowerPC to see what they say.

I may try opening up the PC, unplugging the cable to the fans and/or hub, and plugging it back in to see if that does anything. Unfortunately, I didn't pay attention to the size of the case when I was creating my PC and went with the Lian Evo Dynamic XL full tower case so now I have this 60lb beast to try to handle.

Annnddd the fans aren't lighting up again.

Appreciate the info. I've always used Corsair in the past with no issues, didn't know so many people were having issues with their software.

I appreciate the info. I posted on the Corsair forums and got a response. Basically said I don't even need the additional hub and I should just get a bridge wire to connect the other 3 fans to my other hub as it can support up to 14 devices currently and will support 24 in the future.

I also asked about my H150i AIO cooler and getting it to work with iCUE and was told that I had the previous generation cooler that requires a Commander Core, not the Link Hub, to work and then it should show up in iCUE and I'll be able to control the fans/adjust the LCD, etc.

So, I ordered a Commander Core, 2 short 90 degree cables and 1 long iCUE Link cable as well as one additional QX 120 fan to replace the default rear exhaust fan I currently have. I have a Best Buy Geek Squad membership, so once the stuff comes in my plan is to take it there and have them install the Commander Core & rear exhaust fan, use the cables I got to connect my hub to the other 3 fans, and then verify that my 6 QX fans, AIO Cooler, and single QX rear exhaust fan are all linked and showing up in iCUE so I can control fan speed, RGB, & the LCD display. May sound dumb, I know most of you guys know a lot more about working on PCs than I do, but I'm not really familiar with the components so I'd rather take it there and have them set it up. With the membership it'll be free anyway.

I briefly considered buying a newer AIO cooler, but it's cheaper to just add the Commander Core and link my existing one that way. I should have all of the functionality of the newer AIO cooler, I'll just have to incorporate a Commander Core along with the Link hub for the rest of the fans.

It's kind of a pain in the arse, and annoying as the PC is brand new, but hopefully this will take care of all of my issues. I have to be careful though browsing components, every time I'm on Amazon I'm tempted to upgrade the motherboard, AIO, and add some RAM and an additional SSD. But this system is WAY more than I need right now...I can always upgrade later on if I end up needing to.

TLDR hopefully this just needs a Commander Core and a cable or two and everything will be sorted out. *Crosses Fingers*

Canceled the Commander Core, apparently I should already have one that came with the AIO. Was told they may not have connected everything properly and I might need a powered USB hub, so I ordered one of those.

Take a beat. I realize you want to get this thing perfect, but you'll need to do a little research before buying a bunch of stuff you don't need/can't use.

My first questions is can you call the company that built it and ask them about the connections?
Are you 100% sure you have the commander core, like did you pull the back panel off and see it?
Why did they say you needed a powered USB hub?

He could "upgrade" his CPU to the 14900KS when it comes out this week.

he poster on the Corsair support forums said it has to be there because my fans are running, lighting up, and my LCD display is working. He said those wouldn't be working without a commander core powering/controlling it.

This is probably accurate.

Just from my limited amount of research, it looks like the commander core and the iCUE both use USB 2.0 headers on the MB to send the data. Typically, the case's front panel would have one but the O11 XL only has 3.0 on t[he front. and your MB has two on the board. Looking at your Corsair thread, it looks like your AIO LCD uses a USB header as well. That looks like 3 total, if you remove one of the iCUE hubs and daisy chain them. The MB can support, according to Newegg, 4 more USB 2.0 so I'm not sure a hub is your solution. But keep that in your back pocket, because I'm not an expert.

ETA: After rereading this, my guess is there is a hub in your case already as you have Commander Core, AIO LCD, 2xiCUE hub (4 total needs). I might be wrong about this so grain of salt and what not.

What I would look at doing, and you may need to consult someone with more knowledge, is triple QX120 to triple QX120 to iCUE hub, AIO triple AF120 to commander core, AIO LCD to Commander Core, and Commander Core to iCUE hub. I think the iCUE can handle 14 fans.

That NZXT hub on poster listed is an internal one where it would be SATA power from your power supply, and USB2.0 cable from it to your MB header, and all the rest of the USB 2.0 would connect to it.

It's just frustrating, I spent a lot on this computer. I realize a lighting issue isn't a big deal, but spending as much as I did I want everything to be working.

And you are 100% correct. It should all work which is why you should be pounding the purchase company for answers. They should know how to get this working the correct way.

My drivers are all updated. I contacted CyberPower & spoke with tech support and they said they've been receiving news about there being software issues on Corsair's side. But they recommended I check all connections & contact them if I need a replacement part sent out, like if one of the Link Hubs or the Commander Core is bad.

So, I shut down my PC and opened it up. I can confirm that there are two Link Hubs and the Commander Core present. Everything seemed to be plugged in...although I couldn't really follow connections from the back side of the PC to the front side where everything is plugged into the motherboard as there are so many cables & I didn't want to go unplugging or possibly damaging things when I don't know exactly what I'm looking for.

I did unplug the Link cable at the top of the 3 side fans, which are the ones that weren't lighting up, and plugged it back in. I then closed the case and powered the PC back up and the fans are not lit up and detected in iCUE, showing as linked to the 2nd Link Hub. I can adjust fan speed and lighting effects now.

Hopefully they don't stop working again. But that now leaves me with the issue of my AIO cooler, and it turns out its actually the H170i Elite LCD XT so a 420mm radiator, not showing up in iCUE, which means I can't control the fan speeds, RGB effects, or LCD display. On one hand, it's nice that the other 3 fans are working, but now I need to figure out how to get functionality with my AIO. I won't be able to sync the lighting of my case if I can't adjust the AIO fans, which default to a rainbow-like pattern.

But, I'm at a loss as to what to do next. I do need to take the damn PC back out so I can get some glass cleaner/residue remover and wipe down the glass panels which have a couple of smudges on them. A fun thing I discovered is that when I sent my PC in to CyberPower previously they didn't fully screw in the panel cover of my SSD, and judging by the rattle I'm assuming it's in the bottom of the case somewhere, but I couldn't find it. So, I used one of the top screws for the side panel to screw that in for the meantime.

Thanks, I'll check the video out. Should it be the same, since I have a commander core and not the xt?

When you say USB hub, is that a separate component or do you mean a hub on the actual motherboard?

I'll try to open it up and take some photos the next time I open the case up. I'm assuming the LCD screen and commander core are connected and powered, because the LCD screen does show the temp and the fans are lit and running. I don't understand why iCUE isn't picking it up.

There was a cable coming from the bottom that looked like it had between 6-8 pin slots on it that wasn't plugged into anything, wasn't sure what that was.

Another side note, I bought a Lian RGB cable that plugs into the motherboard and apparently it's attached to a Lian Li controller, I saw that for the first time when I opened the back of the case. Before I sent the PC in that cable was lit up with RGB lights, but since getting it back it hasn't been lighting up either. That dawned on me as I was opening the case. Wonder if that got unplugged somehow, too.

I wonder if I should try unplugging the commander core and then reattaching all of the cables to see if it'll get detected when I start the PC back up? Worked for the QX fans, but I doubt the AIO is going to be that simple.

Part of me is tempted to just buy the updated cooler that runs off of a Link Hub...I would think/hope iCUE wouldn't have issues picking it up then. But I'm managing my "frick it, I'm swapping it out" drive as best as I can. I mean, a commander core should be enough to have iCUE detect it, there has to be an issue somewhere with how it's set up.

ETA: You mentioning the need for the 4 header slots (LCD screen, Commander Core, 2 Link Hubs), would it be worth trying that external powered USB hub that I bought? If I can find out which cables are for the LCD & AIO fans try plugging them into the external hub and see if that does anything? Just tossing it out there, because it seems like I am running (possibly) more components than my Mobo has headers for, so maybe they split the AIO and the splitter is causing the issue?
