OCZ has announced a new CPU cooler aimed at the high-end this week. Their "Vendetta" model is designed to be a low-noise HSF similar to other designs with copper heatpipes and aluminum cooling fins. What makes this particular cooler interesting is the change they have made to the CPU contact, doing away with the traditional base plate design in favor of more direct contact with the heatpipes:

While traditional heat pipe CPU coolers implement a solid base plate design, the Vendetta's three copper heat pipes make direct contact with the processor to ensure the most rapid heat transfer. A novel "dimple" micro-configuration of the stacked aluminum fins adds turbulences, thereby reducing the skin effect of laminar air flow
The unit fits on all modern sockets, including AM2 and LGA775, and sockets going back to 754. It also has rubber grommets for the unit to help reduce noise. You can read the press release or the Vendetta's product page for more info. The unit seems to be retailing at around $37.
