I purchased this for my most recent build, and it is the first time I've tried any form of water cooling. I used air coolers in the past due to the ease of installation and maintenace. However with these new Corsair closed loop systems it makes it just as easy as installing a air cooler. It is zero upkeep, install it and go. Installation was a snap; poped in the i7, used the Intel motherboard bracket, then mounted the radiator, done! It is all self contained, no messing with filling the resevoir up with fluid and risking damage to your components. The only thing that did not really impress me about this system was the included fan. It's okay... But if you intened on some monster over clocks for your processor, then a new fan is in need. I installed 2 higher flow fans in a push-pull setup on my radiator and OC'd to about 5 ghz my idle temps sit at about 32 C. I was very pleased! I've owned it for about 4 months now and not one problem yet, running cool and quiet.
