Dynatron DC1207BMW Heatsink From All Angles

The Fans:
The 70mm fan is rated at 0.2A and is fairly quiet in operation. The fan attaches through the aluminum fan shroud directly into the fins. For the size of the heatsink, I would be tempted to add something a little bit bigger, and maybe sacrifice some of the noise for better cooling performance. The Dynatron fan connects via a 3-pin fan header on the motherboard. On either side of the fan are the guides where the Stainless Steel clips go. The small tab prevents the clips from sliding off the side.

Bare Heatsink:
With the fan removed you can see two things more clearly. First off, the two clip guides are in direct contact with the tips of the fins and provide a good means of clipping down the heatsink without large bulky plastic mechanisms. Secondly, we can see that the fans is held up from the tips of the fins for better airflow by a few millimeters.

Side A:
The side of the DC1207BMW is very plane, with no extra cuts to allow warm air to escape, all exhaust is forced out the left and right sides. The heatsink body itself is 37mm in height, and 83mm in length.

Side B:
Each of the 27 extruded fins tapers from 1mm thick at the base to about 0.5mm thick at the very top. The fins are each spaced 1.5mm apart and the base plate is a standard 6mm thick.

Heatsink Base:
We've always been fairly picky about the quality of a heatsinks base, though over time we have to see that almost no manufacturers machine extruded heatsinks. It is simply much cheaper for them to sand the base "flat", even though this process tends to leave rather deep scratches. Still, given the option between this and a raw extrusion base, the sanded ones are generally better. Raw extrusions, while smooth, are rarely flat.
