Got the CLC 280 2 years ago and have to say I've been quite disappointed with the software. It's only been updated a few times and still doesn't function. I think the last update is well over a year ago. The fan curve is unusable, being locked at 100% at 60C. The LED Sync never worked with my 1080ti properly, and recently the Fans have started failing.
Used to mainly buy EVGA products but now I'm not sure if I can feel comfortable buying an EVGA product not knowing if they'll support it in the future.
So far I've replaced the failing fans with Noctuas (waaay quieter)
