In the above two shots, we have circled the important features that should be noted. In the left picture, the first circle, we see Silverstone’s implementation of a copper slab with aluminum screwed onto the sides of the copper. In the second circle of the first shot, there is a perforated copper sheet to allow air to pass through, thus further aiding in its cooling abilities. Finally, in the right picture, notice the cap around the socket, especially as compared to the Antec (see below), which is non existent.
