Heatsink Top:
With about 500 aluminum fins on the Scythe Kamakaze, there is tremendous surface area to dissipate heat absorbed through the copper/aluminum base of this heatsink. Each pin is oval in shape, about 2mm in diameter and spaced 2mm away from the adjacent pin. The fan bracket is surprisingly well made from stainless steel.

Side A:
The fan shroud doubles as the location where the different mounting brackets are attached to. The bracket for socket 478 or socket A clips screw into place, and by tightening the screw the user applies force to the processor below. With this method, it is very critical to adjust the screws on each side equally. If one screw is tighter than the other it can cause the heatsink to cantilever on the processor core/heat spreader. If this happens, there is a good chance the heatsink will only be making contact with about 1/3-2/3 of the processor, and hence not do its job very well.

Side B:
The socket A clip mechanism is shown. Both clips hold the heatsink in place firmly, but can be a bit touchy to engage on the socket - especially the socket 478 version. A rear support bracket is also included with the heatsink to ensure Pentium4 motherboards are not bent too much when you install the heatsink and torque down the screws. The base with copper insert measures 12mm thick.

The copper portion of the base measures 60x60mm. The copper insert is fit into the aluminum during fabrication, so no soldering or other similar methods are used. The base itself has a sanded finish and is fairly smooth and flat. A sufficient amount of thermal interface compound between the processor and heatsink is still recommended. The holes at each of the four corners are for mounting the fan to the heatsink, and nothing else.
