Commander Core XT/7000x fans not being recognized!

Hi,

I've just upgraded to a custom water loop (Non Corsair....sorry) I'm trying to connect 11 LL120 RGB 120mm fans and 1 iCUE QL140 RGB 140mm fan. I have the commander core xt that came with the case, a commander pro, several RGB hubs, 2 PWM corsair fan hubs as well as an (open) RGB hub that came with another Corsair case. I have the Corsair 7000x case, Asus ROG Crosshair VIII Dark Hero, 1200 Watt Be Quiet Dark power pro PSU. WHen I connect 6 fans to the Commander Core XT, it only recognizes 3 of the LL fans, it never recognizes the 140mm QL as a 140mm. It only recognizes the 3rd, 5th, and 6th fan. All fans work, I've tested them severasl time. I've came up with several configurations and the closest I've got is to exclude the commander core xt completely and run the commander pro with an rgb hub.....one of the exposed ones with a usb connector. I've spent several hours on this. I've researched all over the net, I've read Zotty's posts but none have the XT since it's new. I've called Support and went through what seemed like what he was reading off of a troubleshooting guide (like they are supposed to do) but no suggestions of experience with my question. 

I'm so frustrated with iCue and trying to set this up and not being able to find any help. I'm tp the point of wanting to remove all RGB fans and icue software to just settle for some plan fans to cool

PLEASE, is there someone here than can help me and restore my love for RGB???

 

Thanks for any and all help with this.

Hi Buddy..

 

Hi bud. due to 12 fans. it was never going to be straight forward.

but

 

CoCo XT for 6 fans and CoPro and RGB Fan LED Hub for 6 fans, that covers 12 fans so you should be good to go.

 

for idea's on simplifying.. and i think you have a hang on how the system works. you could bring it down to one Controller.. 

 

CoCo XT and 1 x RGB Fan LED hub and a couple of powered PWM Hubs...

CoCo XT has an RGB Channel for the RGB Hub and you can group fans on a powered pwm hub which would use up one pwm header on the CoCo XT (shows as a single fan in iCUE)..  4 fans in the front? group them... same with the top fans?.. side fans?,, much easier to sync fans speeds when in groups. I have 32 fans on one Commander Pro.. making changes in iCUE is a breeze....

You can actually run all of that from the Commander Core XT.

You have a single QL fan that is the odd one out - put that on the Commander Core XT. It doesn't matter which port but the CoCoXT will let you mix fans on the RGB fans directly connected to it.

For the rest of the fans, you'll have a 3-pin RGB port on the CoCoXT as well. This will connect to a Fan Hub (that'll come with the LL fan multipacks) and then you can put 6 LL fans on that channel.

That leaves you with 5 LL fans ... and 5 open 4-pin RGB ports on the CoCoXT. Connect them to the CoCoXT.

So that's all of your RGB.

For PWM control, you've got the PWM hub that comes with the 7000X case for 6 fans. That'll go into one of the PWM headers on the CoCoXT. You can also use splitters on that hub if you want to put more on there. These will all be at the same speed so you'll want them to all be LL's. As for the rest ... you've got the PWM headers on the CoCoXT and you can use a splitter or two.

Just re-read and saw your issue.

So ... when you go through the auto setup, it doesn't recognize the fans on the ports. What if you do the manual setup? Can you specify the model of fans on the individual port and have them work?

Guys, thank you so much for the education, help, and advice! I'm eagerly waiting to get back to my build so I can experiment with these configurations. It's a community with people like you both that makes it an enjoyable experience. Once I figure out what works, I will update here what I did.

Thanks again!

I've tried that, it shows up as a 120mm fan and not 140mm and the RGB is still off. It just seems weird that when I have all LL fans connected to CoCoXT, only every other one works for RGB. If I remember, I'll send pictures

Update, my CoCoXT may be bad, not sure, ports 2,4, and 6 do not work for RGB for some reason. I've tried several different methods, tested all fan RGB's and all are working. I finally was able to get everything working but definitely not the way it should be I believe.

I have the CoCoXT with 3 RGB connected (1,3, and 5) all fan ports filled. I have 2 RGB hubs, 1 with 6 connected and the other with 3 connected and I have to run them through the CoPro (1 connected to USB and the other connected to the LED port on the CoPro

Seems crazy lol any other suggestions? And do you think my CoCoXT is faulty?

Your CoCoXT may well be faulty.

Question: when you put a fan that works on port 1 on port 2, does the fan no longer work? If yes, then the CoCoXT is going to be faulty.
