FrostyTech has posted an Evercool ND19715CA Copper-Core Heatsink review

We've reviewed heatsinks with similar appearances as the unit we are testing today but so far each version has managed to remain a little bit different than the others. Some versions came equipped with copper additions, others without. In this case, the Evercool ND19715CA sports a 'chewy' copper center. A chocolate bar the Evercool ND19715CA isn't, but with a 35mm diameter copper disc embedded into the aluminum base we should hopefully see some interesting thermal results. While the ND19715CA isn't a true silent heatsink since it measures in at over 40dB, it does manage to operate will low-to-moderate noise levels making it potentially ideal for home computers. One of the other nice aspects of this heatsink is that the outward slope of the fins makes it less likely that closely placed capacitors around the processor socket will cause any interference. A little thing perhaps, but having to bend capacitors to install a heatsink is never a good idea no matter how you look at it.
