FrostyTech has posted a Vantec CCK-7015 1U Copper P4/Xeon Heatsink review

The flexibility of this heatsink comes from the fact that with the right mounting plate it can be used on either a 1U Intel Pentium 4 or Xeon socket 603/4 processor. We'll be testing for the P4 platform configuration, but there is no physical difference other than the retention backplate (both are shipped with the heatsink). 'Skiving' is a process where by thin fins of metal are drawn up from a solid flat plate of copper with the aid of a special cutting blade. The remains of that flat plate of copper the fins are attached to forms the base of the actual heatsink. That means the path heat energy has to take from the base to the fins is homogeneous - there are no bonding agents required because the fins and base are actually one unit.
