LED Failure on Fans


Recommended Posts

Hello everyone,


I took delivery of a new PC today. Its case is a Corsair Crystal Series 680X RGB.

While I was going through the procedure of setting up Windows, I suddenly noticed that all the LEDs on the case fans (there are four) had gone off. The fans were still running.


The iCUE software says that there are no devices connected to either of the two lighting channels.


I cannot find and loose connections.


Has anyone any idea what is causing the problem? I do like the pretty lights - at least the CPU fan display looks nice!


Thanks & Regards, Jim

Check the internal USB connection between the controller and your motherboard. Before it ever detects the software it may light up rainbows, but once it does then it reverts to a blank slate until you give it instructions (lighting set-up, # of fans, effects, etc.).
