Just as I found with the Ice Matrix 400, this heatsink doesn't have the mirror polished base that Deepcool advertises. A mirror polished base means that the CPU makes a slightly higher contact with the heatsink and has a little higher heat transfer rate. For socket 1366, Deepcool doesn't use a back plate, but rather a set of four stick-on plastic nuts. While this method works, it does make reusing these later a little troublesome since the adhesive will wear out after a few uses.
