Legit Reviews posted a review on the Noctua NH-U12P SE2 CPU Cooler
Back in February of 2008 we had our first encounter with Noctua and their (at that time) flagship cooler, the NH-U12P. This cooler was initially release with LGA775 and AM2 platforms in mind. Since its release there have been new sockets come to market. When Intel released the LGA1366 socket, Noctua released a new version of their SecuFirm mounting system and a dual fan version of the NH-U12P, the NH-U12P SE. Now with the release of the LGA1156 socket Noctua has again updated their cooler mounting system to accommodate the new socket and released a new version of the NH-U12P, the NH-U12P SE2. The NH-U12P SE2 is the same cooler that was released back in 2008; it just has the updated mounting system and a couple of extra accessories that the first release didn’t have...Noctua NH-U12P SE2 CPU Cooler Review
