The collaboration of Asetek and Corsair resulted in a product called the Hydro Series H50, a liquid CPU cooler. A simple to install all-in-one kit that has good looks, decent performance, is not noisy... and remains affordable.
This kit is 100% enclosed, doing away with the need for refilling or messy coolants being a danger to your computer's internal parts. And overall the price versus performance, is just really good.
