The last time we had a Vantec heatsink on the chopping block was early on in the summer, and as we move into the fall with the CCK7025 CopperX-478 we can take note of a few things. First off, Vantec heatsinks are just about 100% copper these days (although a new all aluminum heatsink is expected shortly), and secondly we can see that they have upgraded their manufacturing a bit.

The clipping system is the same as was used on the Vantec GSN-7025, and it works just as well as it did on that all aluminum cooler. With the interlocking copper fins forming a support for the clip, we get good compression on the socket without placing too much stress on the underlying PCB. The interlocking copper fins are something I actually saw first showcased about two years ago at Comedex by a company called Neng Tyi.

The aluminum fan shroud stands about 1mm proud of the base surface which gives good scratch protection I suppose. The shroud is held in place with a few screws and while it may look copper in the picture above, it is really just anodized that way.
