A Closer Look
As I mentioned, this thing is a beast. Looks like CoolerMaster pretty much ignored all of AMD's Thermal Solution Design Requirements (seen here on page 11. - Thanks Para! ;)) when designing this heat sink. For the most part this isn't a big deal. Thermalright, Zalman, Swiftech, and other companies have been ignoring requirements for years, and they've worked well.
The base is solid copper, and is machined lap to a nice finish. It's not what most people expect to see when looking at the base, instead it's got a radial look to it. To keep it protected till it gets to you, the base is protected with a plastic protective “sticker”.
Coming from the base of the heat sink, through the 27 copper fins, and extending through the top of the heat sink are 6 heat pipes (3 on each side).
As you can see, engraved on the top of the heat sink is the CoolerMaster logo.
The metal housing surrounding the heat sink, has screw holes on 2 of the sides to attach a fan to. CoolerMaster included one of their own fans with the heat sink, which is nice, since a lot of the high-performance heat sinks usually come fanless.
