iCUE Fan Detection Issue

[Rhyvex]

For preface, I built this PC in spring of 2022. I have 9 corsair LL120 fans running off 1 commander core and 1 commander core XT. 

OS: Windows 11

GPU: RTX 3080

CPU: Intel Core i9-12900k

RAM: Corsair Dominator Platinum 32GB DDR5

Motherboard:  ASUS ROG Strix Z690-E

PSU: Corsair HX Series 1000W 80+ Platinum

Storage: Western DIgital 2TB M.2

CPU Cooler: Corsair H150i elite LCD display

Case: Corsair iCUE 5000T RGB

 

 

The initial setup for the 9 fans and 2 commander cores was quite tricky. I ended up having to daisy chain my commander cores together and plug them both into the same usb header on my motherboard. Initially, iCUE had both visual and functional issues.

Visually, the problems were minor and really only occurred when my pc was asleep or shut off. When in either of these states, the lights that were connected to one of the commander cores would work fine, remaining in the hardware state color and continue spinning at a low RPM (I think this is intended but correct me if I'm wrong). The lights that were connected to the other core did not function correctly. Instead, they would slowly blink in the hardware state color and the fan RPMs would remain high, as if the PC was still on.

Functionally, before arriving at the daisy chain setup I currently have for my 2 commander cores, iCUE would have problems detecting the fan curves on 1 or both of the commander cores. While I could still change the colors of all RGB components in my system through iCUE, I would not be able to control the speed of my fans through iCUE. This is the major issue I had and, up until recently, I thought I had it resolved. I was never able to solve the visual issues unfortunately, but felt it wasn't serious enough to worry about.

 

 

Jump to about a week or two (I have not changed anything with my setup). Now whenever I shut down, restart, or my PC goes to sleep, iCUE will not detect fan curves when coming out of one of those states. Also, now when entering either of these states, all of my fans completely stop moving and the fans connected to one of my commander cores still slowly blink on and off like always.

While I have no solution to my fans completely stopping when in these states and still no solution to the slow blinking on half my fans when in these states, I've arrived at two temporary solutions to iCUE not detecting fan curves.

- The first is completely shutting down my PC, flipping off the power switch, waiting several seconds, and then flipping the switch back on and powering up. (just shutting down does not solve the problem).

- The second solution, while less time consuming than the first but still quite annoying, is going into iCUE and force updating the firmware of both commander cores. This is what I have been doing for the last several days EVERY time my computer turns on, restarts, or wakes from sleep. I currently my PC set to never go to sleep to avoid having to do this fix more than once a day, then I just shut down my PC every night.

 

I've tried reinstalling iCUE, completely uninstalling all other hardware monitoring software leaving only iCUE, switching which usb header my commander cores are plugged into on my motherboard and moving the fans around on the hubs. I'm not really sure where to go from here. My next option seems to be completely reinstalling windows or to start replacing parts. Please help if you can. If you need any additional information, let me know.
