Heatsink Top:
Looking from the top down without the fan shroud we can see right through the heatsink. There really is nothing more to this cooler than the fins and the copper base. A benefit of having the base not extend to the full length of the fins is that exhaust air can be used to help cool the processor as well. Rather than directing the cool air to the sides, it heads straight down and around the outside of the m478 socket.

Side A:
The locking mechanism is classic Intel, and works very well. The copper base plate is 9mm thick, but only 44mm long. The fins range in thickness from 0.4mm to 1mm. The thicker fins being used to support the fan shroud and clipping mechanism. Fins are 34mm in height and spaced ~1mm apart.

Side B:
The roughly 70mm fan is supported by four plastic arms over the heatsink fins. The fan shroud clips into the copper base and helps direct the airflow down and towards the outside of the cooler.

The copper base measures 70mm x 44mm in size and has a sanded finish. The base is nice and flat so only a small amount of thermal compound is really necessary. At the outer edges of the copper base plate are four small cross cuts to help improve air exhaust at the outer edges, and cut down on overall weight.
