AHYUK!

thats cuz mah smert jeans...i puts them thar things on in the morning so's i can use mah calculatin machine, you no, the one with all them purdy buttons, and the picture box like the one in mah livin room, with the foil antennah...AHYUK!

yeah...maybe you should wash your eyes out, and then go read some well written book....that should rid your mind of the horrors of hickish!

Graphite will make a good heat pipe, but a lousy heat sink. It'll move the heat, but you can't spread it out to give it a larger surface area in order to dissipate the heat. Plus it's just too darn soft to do anything with. Think about it, a properly installed copper heatsink will embed an impression of the CPU onto the heatsink itself. At that pressure the graphite will just crumble. Then the graphite will not be aligned along one plane anymore. Then the graphite is a pretty good insulator.

The solution would be to cap both ends with metal to hold the graphite together, but then we're back to discussing which metal is better.

that is what i was getting at...i think that if you made the fins out of carbon SURROUNDED with copper.....then you would be able to use the heatpipe action, without crushing the carbon...® :smile: (had to throw that in)
but i think that copper would be better in this situation, because it should be able to move the heat more efficiently...at least i think it would...
i dont know how they would make the heatsink like that...but i am sure that there is a way...somehow...

glad to see someone thinks i am funny....AHYUK! :smile:

i didnt know that, Churlish! lol
& whats about the Copyrignts ?
did you already thought of ? lol


if you know you don't know, the way could be more easy.

I don't think that would work. The copper would be picking up the heat from the CPU and the copper would be disipating the heat into the atmosphere. In between you would have Graphite, but it will only be transfering the heat from the copper to the copper. The copper is the limiting factor.

hmmm...interesting thought.
too bad.
would have been sweet.
are you sure that it wouldnt transfer the heat from the dissipation plate to the outer tips of the fins?
that is what i was thinking it would do...
like the copper might dissipate the heat near the base, but have you noticed that the tips of the fins are much cooler than the base?
i was thinking that the copper would work sorta like a heatpipe, and transfer the heat to the colder tips of the heatsink, making the most of the heatsink.
taking full advantage of the heatsink's surface area.
also, is there a way to make the heat only travel in one way through the carbon? like a one way valve?
