Seems stupid to say it now, but I didn't buy this product right off the bat because, well, I didn't like the way it looked ~ kinda retro. So I fooled around with a couple of Corsair liquid cooling systems. What a big mistake that was ~ parts that didn't fit, software that was buggy and in the end a fan controller that decided to go AWOL and leave the fans screaming at maximum all the time. How much simpler was to install and how well made, if a little quirky, is this Noctua unit... but oh, how much quieter. Not only that but it dutifully takes its orders from the Asus Fan Expert 2 software without a murmur. And speaking of murmurs, as I write this I literally can't hear it running to the point I just had to go check if it was still working. It looks like an awesome piece of kit and it comes with a six year warranty ~ you can't beat that. Do yourself a favour ~ get one. They're the Rolls Royce of the computer fan industry, sturdy, well made, and do what they are supposed to. I couldn't be more happy with my purchase.
