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.

You are probably correct, as will Heatpipe coolers never become mainstream because they too are marketed towards overclockers. Nevermind the fact that most new processors today come with a heatpipe cooler in the box with the CPU that's irrelevent.

For someone to say that it will NEVER become mainstream is just foolish. Watercooling might not ever become mainstream because of the difficulties of using it, and little gains from using a craptacular system, but something like this may see mainstream use in 2-3 years. Not saying that people won't have better nanotube coolers marketed for the overclockers, but I'm sure they'll find a way to make this thing available for less to the mainstream. More effective than the current heatpipe offerings, but less effective than the more expensive ones made for overclockers.
