The OCZ Hydrojet cooler uses an advanced heatsink material

The first heatsink to make use of directional carbon nanotubes, the OCZ Hydrojet, was on display at Computex 2007. Carbon nanotubes, an allotrope of carbon, are widely regarded as the next major thermal interface material because of their superior thermal conduction properties.  

The contact base of the OCZ Hydrojet is made completely of carbon-nanotubes, which OCZ claims are five times more efficient than copper. Carbon nanotubes have been looked upon as a strong alternative to traditional copper based heatsinks. They are ideal for application in heat transfer products because of their impressive heat-conduction properties.  Carbon nanotube based interfaces have been shown to conduct more heat than conventional thermal interface materials at the same temperatures. In addition, they have shown to be ballistic conductors at room temperature, which means electrons can flow through CNTs without collisions.

Carbon nanotubes are small wire-like structures made out of a sheet of graphene.  The sheet of graphene used to construct CNTs is roughly one-atom thick, and is rolled up into a cylinder. The diameter of the cylinder ranges in the nanometers.

Unlike most other thermal materials, carbon nanotubes are able to move heat in one direction. On the other hand, copper, which is looked upon as one of the more superior thermal materials, moves heat radially. In the case of CNTs, heat is moved along the alignment of the nanotubes.

I'm still waiting on that sub $300 OCZ phase change cooler that they debuted over a year ago. Whatever happened to that?

Boy doesn't OCZ guys chat on anandtech forum... send him a message and ask when can we buy the Sub $300 phase cooling solution they promised a year ago.

Don't forget the liquid metal cooler. I can't even remember who was demoing that.

I believe that was either Saphire or PowerColor, my guess is PowerColor.

I believe it was Sapphire...and I remember seeing a follow-up article based on a follow up with the people who made it... it seems the liquid metal is quite expensive, and the limiting factor had been transferring heat from the heatsink to air... meaning that heatpipes weren't much of a bottleneck, and that liquid metal pipes were just to get people talking about Sapphire...
