Pure Carbon Could Solve All Your Heat Disspipation Worries

[Guest]

There is hope for a future in which computing devices could, theoretically, operate without the need for elaborate cooling techniques.

Graphene solves a lot a problems.

 

[A Bad Day]

Graphene thermal paste, graphene heatsinks, graphene heatpipes, graphene cooling fins and eventually graphene transistors. Yay for no more bulky and heavy air/water cooling setups for monster overclocking.

Then again, we'll find a way to necessitate a bulky air/water setup even with grahpene...

So that which is supposedly keeping the heat in (carbon in the atmosphere = global warming) is now going to have the opposite effect in electronics? Interesting.
It also seems the days of the silicon wafer are numbered.

 

[nebun]

i will believe it when i see it....well the price a little to much for the average joe like you and me

If it conducts heat so well, link the Graphene to the chassis of the case and dissipate the heat through that? But the cases would kinda have to be Aluminium or some other good heat conducting material.. :\

 

[JohnnyLucky]

I can't think this one through. The old Star Trek movie about "carbon based life forms" keeps popping into my head.

 

[chumly]

Too bad its expensive as all hell.

Could this mean the return of the high-end single-slot graphics card? Probably not since they'll just clock the things so high they'll still need dual-slot coolers :-(

Carbon dioxide is very different from grapheme. CO2- trap heat vs graphene- good conductor.

It's been well known in materials science and engineering circles for years that diamond, aka carbon, is the best heat conductor known. What makes diamond unusual is that it's a great electrical insulator while being a great heat conductor (this is counter-intuitive as good heat conductivity and good electrical conductivity go hand in hand, except with carbon).

The whole reason we don't have diamon heat sinks is because of the diamond consortiums like De Biers. Artificial diamond is indistiguishable from natural diamond when grown properly (and GE knows how to do it). As such, the diamond consortiums have leaned hard on the producers of artificial diamonds. One can only hope that this changes.

I totally sing up for a diamond heat sink. But, by the time we get them, we are going to be in 10mm features on the silicon chips, with very low voltages. this means the chips may work fine in normal temperature. we may not need them by the time they come around. My phone does not have a huge copper heat sink, and 5 years from now those are the chips we'll be running on the servers and desktops.

Stupidest comment of the month.

While for sure heat is important, let's remember that this won't effect battery life. So while this is certainly useful, we are still stuck with relatively low powered devices in mobile units, at least until something can be done on that front.

I see this to be less useful in mobile devices than in OC'd systems where people are trying to max out their system performance. Not that I am saying it is useless in laptops and tablets since it obviously isn't.

The problem is that graphene isn't stiff, it's like super flexible paper that's tougher than steel. You'd have to stretch it over a frame. That would also be a problem since there has to be a way to connect the case to the components for proper cooling.

If pure carbon is what is needed, use artificial diamonds hehehe.

 

[palladin9479]

Basically they use this to make a thin layer for thermal interface materials. Once manufacturing capability is good they can further create graphene heat pipes which would further enhance it's thermal transfer capabilities.

"could essentially prevent laptops and other electronics from overheating and enable chip companies and
device manufacturers to pack much more powerful chips into mobile devices."

Not without a fan that has a good air supply. Like say a laptop that just has 1 suction vent and you put in on your bed....

in all honesty when Graphene is finalized and it is actually put out of the consumer products, you probably won't be able overclocked it. I remember reading about how Graphene is able to handle speeds that come close to light.

 

[bin1127]

military equipment should use diamond conductors. at least I would stop wondering where the billions are going.

 

[vaughn2k]

Aluminum has a thermal conductivity of 270 W/m-k
Copper has 480
Graphene is between 4000 to 5000

It figures...

 

[intel4eva]

Start mass producing this shit son. The market for this shit is huge, and includes damn near everybody. The cost to set up fabs for the material is astronomical, but the payoff is even bigger.

 

[teodoreh]

heatsinks are forever..

 

[pjmelect]

A little known fact is that diamond is the best conductor of heat which is just another form of carbon.
