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.

Safety???

I'm all for new technology but is it safe to put a bunch of nanotubes on a commercial technology like a heatsink. In the headlong rush to get nanotechnnology out-the-door companies are failing to test if these products are safe to humans!!! Often they try to pass off their nanotubes as being as safe as graphite, but in fact nanotubes are not soluble in water and behave like asbestos when they get in the lungs, and research into these effects is still in a very early stage:

The research cuts both ways though too. Of the very few studies out there, someone has found that minnows get deformed in water with C60, but someone else has found that diluted C60 will pass right through organic tissue.

Semi-off topic: Asbestos is relatively safe when handled and used properly. There's no reason to think CNT will be any different IMO

That's not saying much. By definition, everything is safe when handled and used properly. Guns, knives, flammables, poison gas, mercury, radioactive materials. Use it properly!

Which is probably why its perfectly legitimate and safe to have all the things you listed :)
