I want a diamond heatsink

[madcow235]

I read in my chem book diamonds have 5 times the heat transfer ability of silver. I wonder how much an industrial diamond the size of the core would cost :). but lapping the base would be a pain

but lapping the base would be a pain

Not if you had some Diamond Paper :D

[madcow235]

Yes of course :)

Hey madcow235,
You are quite right about the thermal properties of diamond but I believe the catch is you need a single crystal of diamond as opposed to an amalgam (sp?) of diamond crystals . I read somewhere that you need a contigous (again,sp) carbon chain to afford the thermal conductivity desired.
Bottom line.....you conduct the heat via diamond HS to.....what?
Diamond conducts heat fast but what do you conduct (transfer)
the heat to besides water?
Diamond is a "fast" conducter of heat but you can't have fins of diamond to dissipate the heat to air or water.
just my o2......feel free to flame or teach :)
Never say can't :eek:

It would make a fine heatspreader. The russians are now making synthetic gem-grade diamonds. Talk to them. Maybe they'll listen.

you know, if cpu vendors decided to use this as their integrated heat spreaders *cough, amd* it would allow more possibilities for air cooling on faster cpus.
my biggests complaint with air is the noise factor. this is most likely because amd hasnt got brain enough to increase the size of their heat spreader as intel did. a dimond heat spreader on the opteron would be great i think, allowing for use of smaller, less noisy hsf's of course, using this in a peltier coldplate would just kick. coat the bottom of your copper water block with a diamond dust.

[Caffinehog]

First, the diamond has to be in a single crystal to work. Second, a thin layer isn't going to make any difference.

[BoB NaPaLm]

I was thinking that because the heat would still have to go to the heatsink and so that would be the limiting factor.

But then again I though that if the chip had a diamond heatspreader, at least it would make sure that it wasn't causing your lovely expensive heatsink to perform slightly badly. But I think that it would not fit in with AMD's keep all costs to a minimum way of doing things.

seeker u said cant... ... sorry had to be a jack off...

if u goto www.wc101.com they have a nice set of forums this is JFETTIG'S te he goes over the topic of a diamond water block learn some there. even has some linkage.

This is the worlds largest Diamond in its uncut state 3106 carats, known as the Cullinan diamond

What a tragedy they turned it into this rather than make a heatsink out of it :p

Carbon nanotubes are even better conductors as they are uniform and can be shaped (no need to lap it because it could be formed at only a few atoms apart) any way you like although cost would be in the billions, but man just think about it, it would even be bullet proof

Then I could dress my computer up in gangster gear and call other people's computers his "bitches".

[R.Rabbit]

heheehe, some i read some where that somebody made some custom ARCTIC DIAMOND(mixed AS3 with diamond dust) but it actually made the temps worse because of the whole 1 peice deal

[Tecumseh]

Diamond does not have to be a single crystal to be effective.
Synthetic diamond made by CVD methods has been used for
years in military cooling systems. This stuff usually looks
black like bort. Heat spreaders are the usual application.

Nobody has the technology to make it cheap enough for the
PC industry. :(

[f00t]

why dont you just buy a good peltier and some watercooling and pint it silver, or gold or whatever you want. :) this would be much cheaper and probably just as, or more, effective.

[Serville]

Diamong heatsink ?
You must be Donald Trump !!!

[AntmanMike]

Nevin (Arctic Silver) said a while back that he experimented with Diamond Paste. These were the problems:

1. They KILLED the mixing machines.
2. It did not conduct heat very well.

[madcow235]

I must win the lotto and buy a diamond making machine. And then i will make a huge heatsink and be poor. BUt i will have the best overclock :)

[TheCor4D]

since diamond would absorb the heat faster, it would have to have massive fans to get rid of the heat, isnt they why on the SLK-800 you need a pretty hefty fan to see good results? what dooes is it a very hot heatsink going to do? you have to keep everything cool.

Something about this just made me burst out laughing hysterically. I can just picture a computer in a baggy jean suit with a bandana around the top. Scary.....:D
