Purdue's carbon nanotubes could trump heat sinks
For the second time in the past few months, Purdue University is hitting us up with a newfangled idea to keep future rigs cooler. This go 'round, engineers have purportedly figured out how to "grow forests of carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to heat sinks." The nanotubes have outperformed "conventional thermal interface materials" in testing, and being that they don't require "elaborate clean-room environments" to produce, manufacturing them should prove much cheaper to boot. Regrettably, there's no word as to when this development could go commercial, but with users demanding more power and less noise, we're sure there's a market waiting.

dude, get those janitors out of the lab!
Don't make more energy efficient chips. Don't make less leaky chips. Use carbon nano-tubes.
Learn to recognize a joke.

-as being childish and in poor taste.
Recognize the inappropriate.
Racist prick
In the future, compuers used for pornography will NOT overheat.
It would feel nice to boast, "Yeah, just got my new Nanotube heatsink in today to keep my Pentium 8Ghz 4 core cool while playing Quake 6."
I for one welcome our carbon nanotube underlords!
God, that saying is SOOOOO friggin annoying.
Are there any products that the average geek out there can buy, today, that use carbon nanotubes? Or is this another high-temperature superconductor dead end?
I am pretty certain that they claim that these are easier to manufacture than the chip itself.
"Purdue's carbon nanotubes could *trump* heat sinks"
From the article content it sounds like the nano-tubes work in conjunction with the heat sink by replacing traditional thermal bonding compounds such as Arctic Silver. So no trumping would occur!
My thoughts exactly.
This is not a new heatsink, its a new experimental TIM
I agree. Sounds more like interface material rather than the actual heatsink itself.
Maybe someday instead of overpaying for arctic silver, people can overpay for carbon nanotube forest growing fairy dust to sprinkle on their new cpus.
Unfortunately the writers don't always have a firm grasp on the technical underpinnings of the stuff they love to pontificate about.
It's an odd thing, and unfortunately quite common on the "tech blogs".
That is a seriously old manual tuning match in that wave guide.
seems to be based on a reallllly old Etch system
@US
You suck.
GO BOILERMAKERS!
What I am most interested in is using lab grown diamonds as heatsinks. I read an article a few months back about how much more efficient diamonds are at heat transfer than any other material used in heatsinks now.
The major problem however (other than cost) is the fact that natural diamonds are not large enough or uniform enough to use.
I can not wait until they perfect making synthetic diamonds.
Found the wikipedia article on synthetic diamonds: http://en.wikipedia.org/wiki/Synthetic_diamond
This is sort of parallel to what they are doing here, Diamonds are just extremely densely packed carbon.
Synthetic diamonds are not all equal. The ideal way to make diamond circuits is using carbon vapor deposition. Unfortunately, laying down carbon atoms one layer at a time in a highly charged plasma takes time. So it makes sense to maybe make a diamond that's 0.995 ct. to weigh 1.01 ct - and thus worth a lot more (1 ct is a "magic number").
But CVD should work great for diamond-like ICs. They would operate cooler and transmit eletrons faster than silicon. They already make lots of things out of synthetic diamond. Windows on spacecraft, scaplels, etc. Why not the processor in my MacBook Pro? :D
Diamonds are carbon too.
@Wwhat I realize this, as was noted in my immediate reply to my original post.
to my knowledge nothing conducts heat better that diamond( nearly 100% ) so no wonder these nanotubes which are also just carbon conduct so well. maybe with some nano heat pipe effect yet?
you want some really large synthetic diamonds? make your own heatsink, go here : www.cvd-diamond.com commercially available! CDsize wafers, polished or raw.
"to my knowledge nothing conducts heat better that diamond( nearly 100% ) so no wonder these nanotubes which are also just carbon conduct so well. maybe with some nano heat pipe effect yet?"
Not sure about the thermal conductivity of diamond, but carbon nanotubes are pretty interesting in this regard. Apparently they're extremely good thermal conductors along their axis, and extremely poor perpendicular - your "Nano heat pipe" analogy is bang on.
I know diamonds are one of the best thermal conductors known to man, you can check out that wikipedia article if you have time I think it references it in there.
carbon nanotubes....once we perfect those, we can build space elevators!

sounds just as stupid the second time.....
Boiler up!
BTFU! HAIL PURDUE
Making your thermal conductivity needs come true.
GO BOILERS!!!!
This photo cries out for a caption contest.
Why, so we can hear all of the racist comments?
I wasn't even thinking that. Look at his body language...that is the point.
Shame on us.

What the hell?
Wait... I think i hear something... BOOM!
