FrostyTech has posted a Bitspower NP60CS Copper Skive Heatsink review
So far this is the first all copper heatsink Bitspower have brought to the table, and as far as a first run goes, the NP60CS works quite well. As Skive heatsinks go, the NP60CS doesn't boast the highest of fin densities, or the thinnest of fins, but it does perform admirably, and that's always the most important aspect.Read more
Improving on their manufacturing techniques, Bitspower have junked the 'bent look' their older heatsinks had, and gone for a more upright look here. This means that the fins are more straight and upright, and remarkably smooth on both sides. Generally, the skive process creates fins with a smooth and a bumpy side. This is a direct result of the way the metal is sheered off of the flat plate to form the fins.
