Philipp 6 Posted August 5, 2001 FrostyTech has posted a review on the Dynatron Model-O Copper Microfin Heatsink The Microfin technology used in the Model-O heatsink is quite simple from the outset. Small flaps of copper have been skived from a flat plate of copper to form fins which stand upright, creating a seamless thermal joint. With the Dynatron Model-O, both fins and base are made from one solid piece of copper - there are no joints whatsoever. The only component attached to the one-piece heatsink is the aluminum shroud used to support the fan, and direct airflow down into the fins. Now we´ve seen similarly formed heatsinks before (ie. the aluminum AVC Skive), but so far none have had anywhere near the same degree of fin density. In fact the Model-O boasts sixty 0.35mm thick copper fins set at a pitch of 1.0mm. The high-density fin design creates a larger amount of surface area to diffuse heat to the surrounding environment, and should theoretically make this a more efficient heatsink.
