When Corsair released its closed-loop H80 water cooler in 2011, we found it to be one of the best-performing dual-fan kits available. It was also very loud at full blast and cumbersome to install, and the updated H80i model sets out to address these issues while also improving performance.
Note: This review was taken from the March 2013 issue of the magazine.
If you're not yet ready to dive into the deep end of water cooling by building your own setup from scratch (apparently not as popular as it used to be, hence the demise of Danger Den) but still want to get your feet wet, then a self contained liquid cooler might be what you're after. There are plenty of options to choose from, including two new models from Corsair, the Hydro Series H100i and H80i.
