Most of the issues they have is software related. 4-5+ years of Corsair Link, their Cue software is OK at best and probably the only thing working decently atm and idk bout the rest. I was tortured for 2+ years with the CL with empty promises from Corsair. Stopped going to their forums, etc. The CL's have since been replaced a few times. I have two CL's sitting in a box collecting dust and used RGB LEDs. Mind you at the beginning of CL, I spent $150+ for the originals and went through a never ending roller coaster with them after. A simple free monitoring program did a better job than it. I couldn't handle it anymore as it was taking a emotional toll out of me and so I parted ways and couldn't have been happier since replacing it all with the Aquaero 6 for my monitoring and controlling.
Mind you I still use the AX1200i from them. I have their 2nd gen. PSU after the first one seems to be the culprit to my blowout into my introduction to X99 for the first time. Took out the X99 Classified MB, GTX 480 and a Corsair Link and it's separate Corsair Link Lighting node that they don't sell no more. The Corsair Link had continuous white smoke coming from it a few minutes after of the blowout. Was ready to throw it inside a bucket of water. I determined since Corsair won't, that since their first gen. PSU's came with a old firmware that had OCP disabled by default, we found out through a 3rd party doing investigation, that was the cause of my blowout. They than 3 months into release changed all the PSU's with the new firmware without saying a thing about it to the public. The way the old one worked is, you needed to load to windows and have Corsair Link software enable OCP was the only way. They replaced the PSU with a newer firmware that has OCP enabled by default from the start and haven't had a problem since. The same thing had happened to another reviewer site but the fingers were being pointed everywhere by Corsair (PSU) and Asus (MB) as to what the culprit was from their blowout.
The elephant in the room here is, most of their components and products they sell are in relation to their CL software unfortunately and still haven't gotten it right yet. No public apology either from them for the CL. They did apologize about their RGB keyboard issue but that's a whole other story.
