Hello,

Hoping someone has experienced this issue. Here are my specs first.

ASRock AB350M Pro4 Micro ATX AM4 Motherboard

Corsair Vengeance RGB Pro 16 GB (2 x 8 GB)

Corsair CXM V2 (2017) 750 W 80+ Bronze Certified Semi-modular ATX Power Supply

EVGA GTX 1070 SC

Corsair k55 rgb gaming keyboard

Windows 10

 

I am using 3 LL120 RGB Fans and Lighting Node Pro to control them. Everything has been fine for close to a year. Now all fan lights went out with the exception of 1 LED in the center of Fan #2.

 

I have Checked all wires. I have moved them from channel 1 to 2. I have reinstalled Icue. and Nothing happens. Changed the order in Icue as well.

 

RAM and Keyboard I can control just fine and all lights work. However on the RAM I have lights all white and a few look light purple.

 

I would appreciate an ideas. I did open a ticket with Corsair and have not received a reply yet.

 

Thank you

The lights are serial, so if LED #3 on fan 2 goes out, the lights stop there. You will need to systematically rotate the fans at the Lighting Hub 1-2-3 to figure out which one is the dud. I would start by moving 2 -> 1 and 1 -> 3. The fans must always occupy slots 1-3 without skipping a slot. You can use instant lighting Red-Green-Blue-White to quick check specific LED bulb types.

 

If that goes nowhere, you may be looking at a controller issue on the RGB Lighting Hub. If you have a spare, you can swap it in, but I suspect not. You will need to then contact Corsair support to get a replacement.

Thanks I will give that a go. What is really odd is this happened right after I bought a Rift-S. Last night had the Rift on and the lights came back on for a while. Maybe a strange coincidence. Thank you for the input I very much appreciate it.
