Question RGB dimmed or off completely on Corsair fans ?

[dmk1701]

Hi

I built my PC back in 2020 and it has worked very reliably since then however in the past few weeks I've been having issues with my Corsair ll120 fans RGB. The fans spin fine, so no issue there, but the LED lights on 3 of the 6 fans are faulty. Two of them don't light up at all and one is sort of semi-lit. Previously, they would come on randomly and work fine and then go again next time I switched my PC on but now the issue is constant.

I actually noticed that the problem appears to have been initially started when I would leave my PC in sleep mode for long periods although that may be coincidental. My PSU is 850w unit. The fan headers are connected to a commander pro and the RGB headers are connected the the lighting hub which came with the case. The case is a Corsair iCUE 220T ATX. Motherboard is MAGB550M Mortar.Using a liquid cooler, also Corsair, which is working fine including the lighting elements.

Would greatly appreciate any ideas on where the issue might be, I have fairly limited knowledge and built the rig by following youtube tutorials

Thanks

have you tried using Icue software and see if you can control lights?

if they anything like ML120 you should have a hardware and a software profile choice.
hardware is what they show when windows is off
Software is what shows when Icue is running.

could see if this works to reset lights to factory defaults - https://forum.corsair.com/forums/to...s-factory-lighting-effect-how-to-get-it-back/
