Graphite

[Agent_Mull]

Would graphite make a good thing to put on the bottom of your heatsink. i tried looking for the heat capacity or what ever the official measurment is, but i couldnt find it. Anyone tried it?

Pyrolitic graphite heatspreaders are what you need to look around for. The testing shows them to be around 1700 W/mk thermal conductivity vs copper 400 W/mk
Some interesting data here. http://www.coolingzone.com/Guest/News/NL_APR_2001/Carl/Apr_CZ_2001.html

Woah woah woah, do you mean in replacement of thermal paste?

 

[Jognt]

wth, i thought graphite was supposed to be for isolation not for conduction :S

 

[Agent_Mull]

I might try putting some on the bottom of my hs.

 

[wildfrogman]

No, this would be more geared towards replacing the caps on amd~p4 cpu's. Or maybe an insert like the alpha pal 8045 and instead of copper have it be that.

but wouldnt it help allittle bit?

or could i mix up some graphite in my as3?

 

[Bensa]

I knew I had a reason why I collected the graphite deposits from the yard

Probably not. Thermal interface material isn't all about thermal conductivity. It's about filling the spaces between your heatsink/waterblock and your processor. So, if you have some (relatively) large particles of graphite and put them in a thermal paste, they will create extra space and decrease thermal conductivity.

but the siver could fill in the gaps while the graphite conducts the heat.

Anyone up to the task for the experiment?

 

[Agent_Mull]

Yes, anyone
I might try putting graphite on my heatsink, but not mixing it in the as3

 

[Agent_Mull]

Ok. the graphite powder i used was hard to get onto the copper of the HS. but i mixed some up in AS3, but then i wiped the as3 off leaving the graphite on the metal. Results are yet to be determined.

Also i have some 2mm graphite pencil leads i might try putting in the hs some how to see if that might help dissapate heat faster.

 

[Agent_Mull]

doesnt look like its helping any

Like I said, it will only hurt your performance. Thermal paste is meant to fill gaps only. Any extra space is just hurting performance otherwise.

 

[jhl3]

Well I tried it and gained a half C. Removed it and tried again with graphite for locks and got back to where I was before the graphite. Anyone got better results?

BTW it was mixed with AS ceramique. Quantaties too small to measure with what I have.

 

[Agent_Mull]

Actually now im running about 2-3°c cooler. Maybe it was just that i wasnt using it. tho i was running Seti.

just a little FYI. There used to be some TIM's that were primarily made of graphite. Both Intel and AMD had graphite based TIM's at one point or another. Intel for the first generation P3's and Celerons, and AMD for their early K6-2's.

the only thing i did not like about it so far is thay did not mension sliver look at that list agen i think sliver is about 700

Anyone know what the heat rating of Glass is?
