Vantec CCK6012 Copper 1U Heatsink Review
at Vantec have recently come out with a very cool looking solid copper 1U
heatsink. The new CCK-6012 copper 1U heatsink immediately caught our eyes
because each and every fin has been cut from what was once a solid. This means that
the much dreaded thermal interface between fins of the heatsink and the base is
a moot issue. By cutting out the fins the heat energy should have
a clear path from processor core to fin tip, and that is always good for thermal
conductivity. In other heatsink designs where solder is involved, the thermal energy must travel through a region which is less conductive then copper, and if there are any gaps or areas of poor contact that can further deteriorate things.
As if that weren't enough, on top of all this copper Vantec have added another layer of "plated copper" to prevent oxidization, keep everything shinny, and probably just for good luck :) Rest assured this heatsink looks like a million bucks, but with all the gloss and copper goodness has something gone unnoticed, and more importantly, will it perform the duties of a 1U heatsink well?
The copper 1U heatsink is pretty tiny by most
standards, and there really isn't much to comment on about it construction. With only a few
millimeters of space inside a 1U server, the 10mm fan is pretty much standard,
and realistically there isn't much further to go.
Going of on a tangent for a moment, one of the first things that crossed our
minds when we saw the CCK-6012 was for another more passive use. If a few of
these copper coolers could be rounded up and cut into appropriate sizes they
might make really good RAMsinks for a videocard. Attaching the heavy copper
heatsinks to the memory would a bit perilous, but I suppose if a good
thermal epoxy were used then things would be alright.
