Bests & Worsts Reviews from Amazon

First, let me say that I've been building systems for over 20 years, and have worked with or installed just about every computer cooling system ever made. When I bought the H80i I wanted something simple to install, extremely quiet, and effective with my i7-3820. My computer is on 24/7 and I really didn't want a cooling system that didn't cool well or was so noisy as to be distracting. While the H80i cools my cpu very well, the fans that come with it are horrible. The noise level when playing a game or doing anything even slightly CPU intensive is unacceptable. As soon as any of the cores go above 15% usage, the fans go into high speed and sound like a vacuum cleaner or a leaf blower. When I heard how noisy it was, I almost decided to get rid of the entire cooling system and try another type. Fortunately, I decided to take the easy way out and try replacing the fans with quieter ones. I ended up buying two of the Black COUGAR CF-V12HB Vortex Hydro-Dynamic-Bearing 120MM Silent Cooling Fans for about $20.00 each, and replacing the original fans with them. Definitely the best thing I could have done. The H80i now cools just as well and makes almost no noise at all, even at high workload. Except for the fans, I highly recommend this cooler. It cools well and is incredibly easy to install. If Corsair had provided fans like the ones I ended up buying, I would have given it a 5 star rating. Keep this in mind if you decide to buy it.
