Silence, performance and overclocking. These three words don't go hand-in-hand with Intel's default cooling solution that ships with their retail processors. For this very reason, enthusiasts have to rely on other companies to design superior heatsinks. Some large players are, for better or worse, more widely known than others, while a few of them truly stand out for their premium products. Noctua is definitely part of the latter. They have been in the business since 2005 and have released quite a few solid products including the NH-U12P, which is among the best heatsinks available on the market.
