Already have one in another machine. Dead quiet and easy to fit. ( watch the YouTube video if not done before). My only gripe was there were not diagrams as to using new AMD bracket. But I found after a little research Corsair have one on their site. Really please even though this was a refurb at a much reduced price it’s as good as brand new
The unit I got was near perfect condition, some of the radiator fins were bent but that was all covered by fans and dust filters however the actual block and tubing was pristine. Temperatures are great on my 4790k at 4.7ghz and it’s really quiet (I have noctua fans though). I can barely hear the pump as well
