LL140 RGB fan - leds not working


Recommended Posts

I just set up my new fans and I can't get the leds working, everything is plugged correctly


What I tried

-connecting a different USB cable

-reset button on the node

-testing power on connector that connects fan hub to the lighting node (5v on one pin on each device)

-testing the last pin on the 1-6 connectors on the fan hub (5v)



I don't know what else to try, I think the fans might be DOA

4. installed iCUE from website


5. Tested -> not working lighting node still not detected (only my m65 mouse)

Yep tried that, I plugged in a different USB cable from the rear IO to the node and no change. I also plugged my keyboard in to the USB cable that came with the node and there's nothing wrong with the cable.

I tried unplugging the sata power and plugging back in a few times and still no change

Tried a different port on the power supply, still nothing
