OCZ Displays Carbon Nanotube Cooler

[DasFox]

The first heatsink to make use of directional carbon nanotubes.

VERY cool stuff. Wonder how much it cost to build.

WOW I can't believe all the geeks around here didn't jump on this post...

Hmm

Well a bump for those that missed this cool thing.

neato.

$$$

So they have a base material that conducts heat well... One can already have their HS base coated with diamond if they choose.

They key is that the words "carbon" and "nano" move a lot of units...


they went for the deuce

Well, the picture looks like they made it out of a few circular pieces of aluminum and an old jam jar

Neat, though. I assume they use a small layer of the carbon to conduct heat to a larger aluminum sink with lots of fins.

screw that... i'm waiting for this

I sent this link to my friend but since he has used liquid nitrogen quite a bit, I think this will be a step backwards in his PC cooling.

The good ole' boys at Intel that got lambasted for the toasty P4's are kicking themselves for not proposing such a thing

Id like to see some FE-SEM and HR-TEM of OCZ's CNTs though. I doubt they are without a huge amount of defects. The most common way to vertically align carbon nanotubes effectively, easily, and repeatably so far is Microwave assisted and or Plasma enhanced chemical vapor deposition. Unfortunately upon inspection of FESEM or HRTEM, they usually are heavily defective "coffee-filter-stack" filamentous carbon rather than tubular filamentous carbon (CNT).

Diamonds don't conduct heat well at all.... very poorly in fact.

Diamond has an average thermal conductivity of 1000 Watts/m-K. Only problem with diamonds conducting heat would be related to available surface area...

CNTs can have up to 6000 Watts/m-K thermal conductivity as long as their chirality permits. (you want the metalic which occurs if the n,m value is divisible by 3)

Is there no hardware forum anymore?

yeah saw this a while ago. let's just see some benchmarks.

That's a hell of a lot better than I thought it was. That's a lot more heat conductive than most gemstones. Diamonds really are special.......

Try up to 2000.
