Lian Li SL 120 Fans 120mm Disappear from L connect 3

Status
Not open for further replies.
Hello Everyone!

I have 9 Lian Li Sl 120mm fans installed in my pc with 3 connected directly to my motherboard and 6 to the controller which comes in the pack.
3 of the 6 fans are installed on my radiator.
I am currently having problems with hardware detection of my fans.
The fans show up in my device manager and L connect for 5-10 minutes after booting up my PC but soon they disappear from L connect and my device manager and take my NZXT cooler with it.
After about 10 minutes or so my pc will give a notification that it was unable to recognize two of the devices connected to it and in the device manager it will give me 2 errors in the Universal Serial Bus Controller.
The error is : Unknown Usb Device( Device Descriptor Request Failed) (Code 43)

If i then check NZXT Cam, my cooler wont appear on there either and will say no NZXT devices available when 10 minutes ago everything showed up and was working fine.
I was thinking it could be an issue with the computers USB hub but if that was the case the fans/cooler should not show up when I boot the pc.

My Specs: Asus Maximus Z690 Hero
DDR5 32gb ram
NZXT Kraken X 3
9 Lian Li Sl 120mm ( 6 Connected to the Casing 3 connected to the radiator)
MSI 3090Ti Suprim edition
Lian Li O11 Evo Dynamic Casing.
I have tried pretty much everything and nothing seems to work.
Any help will be appreciated,
Thanks.

You didn't mention how your fans were setup, but I would ensure they're plugged in as recommended by ASUS:

Just to confirm,

The pump is plugged into the AIO_PUMP header,

The radiator fans are plugged into CPU_FAN and CPU_OPT,

And the chassis fans are plugged into CHA_FAN (This is where I would use your fan hub)?

Are you still having the issue in this configuration?

Do the fans stop spinning, or do you just lose them in the software?

Have you tried a software other than NZXT Cam? I remember hearing it had some issues with non-NZXT products, particularly AIOs/coolers.

You could check the fans in the BIOS, or install something like HWInfo64 (My monitoring program of choice).

The fans that are connected to the hub, I lose them in the software but they do keep spinning and their RGB works as well.
They disappear from both NZXT Cam and Lian Li L Connect 3. I haven't tried other software's as I doubt they will work since my pc stops recognizing the fans connected the the hub all together. The hub is connected to my motherboard through a USB cable and two sata power connectors to the psu. I've tried completely reinstalling my windows to check if it was a driver issue but the problem still persists. It could be either the hub that's causing the issue, the USB cable, or the USB connection port on my motherboard but I doubt that's the case because if it was it would not recognize the fans when my pc boots.
