Cools effectively, looks great, lightens your wallet

The cooler is easy to install, and definitely does the job! Paired with Thermal Grizzly Kryonaut thermal paste, it lowered the temps on my i7 by 10 degrees celsius. I run this in a Phantex Enthoo ITX case, and it is relatively quiet, even up close. The radiator has a solid build, with nice fin array. Hoses seem securely fastened. The LEDs are bright and crisp. And those sweet ML fans! A bit pricey for what you get considering the competitors out there. Almost all good stuff, except...
After six months one of the blue LEDs on the cooler has failed. I've followed Corsair support's troubleshooting steps with different versions of iCue to no avail, including the most recent (iCue itself is a bit of a mess). The oddest step was to reseat the cooler; not sure how that is supposed to resolve the LED problem. Initial engagement was good, but now I've been waiting for an answer on my RMA request for almost 2 weeks now; it's like Corsair has ghosted me.
Update (7/15/2021): A day or so after my original review, things finally got going again with Corsair. They provided a paid shipping label for RMA, and I sent them the aio pump, radiator and ML fans still attached; all the accessories and such stayed with me. About a week after they received the unit, I received back another retail unit, new in box. This was quite surprising as I expected a refurb. Took me almost a week to get to re-installing the AIO. Now I'm back in good order. Overall, I'm bumping the rating back up, and apart from the long pause there in the middle of this, I'm pleased with the response after things got moving again. Now just hoping the new unit doesn't have a similar issue in 6 months.
