Silver, and something else.

I've took a look at it, and did a little write up. If you are intrested, please take a look, and give me your feed back, good / bad / or otherwise.

XRD of Arctic Silver

Oh, yeah, and water wetter has a pH of 10.4.

cheers!

Was that Arctic Silver, or was it Arctic Silver 2?

I was under the impression that Arctic Silver had zinc-oxcide in it, and that Arctic Silver 2 does not.

Opsy - arctic silver 1.

And as far as I knew they always had silver (and the side of the tube even says so).

They always have had silver in them. But I was under the impression that AC1 had zinc-oxcide in it as a filler, and that AC2 was "un-cut". But I guess that if you didn't find any zinc-oxcide that they must have never has zinc-oxcide in them. You should get some AC2 and do a comparison between them, that would be cool, you could write a little article up for the front page while yer at it :)

I wonder if they could make a Artic Gold? That would be neat. :)

Gold actually conducts heat less well than silver. So Arctic Gold would be both more expensive and less effective than Arctic Silver.

How about "Arctic CVD Diamond"? AFAIK nothing conducts heat better than CVD diamond, but I don't know if it can be "micronized" to use in thermal paste.

I wonder if silicon can be soldered to a heatsink. Here is what I'm thinking:

Take a big MoFo heatsink, a CPU, and some silver solder (the good stuff thats 90% silver) and solder that puppy on. Think it could be done?

assuming you are not kidding, you could Silver Solder to an all-copper base, but if it's one of those copper inlayed aluminum HS, the temperature required for Silver Soldering might cause mechanical distortions that compromise the contact made between the copper inlay and the aluminum it is pressed against. The pool of Silver Solder would not "self-level" and you would have to do some serious milling to get it flat, followed by lapping to get is smooth. Considering the slight edge Silver has to Copper in thermal conductivity, it represents a lot of work for a small return in performance.
that, having been said, I still have not heard back from any HSF "gurus" about the recombination phenomenon I have been experiencing when using AS and a copper base HS. If this is the first time you have heard about this. Basically, i have started seeing small flecks of solid Silver adhering to my core after running for a few days. It tends to attach to the slightly more porous areas where the writing is etched into the cores surface. On a tip, I took a multimeter and observed a small amount of current flowing from my coppe base HS to chassis ground. It is a DC current in the area of 3 ma. Not much, but definitely there. I do not see this current with an Aluminum HS. I wonder if there is some galvanic reaction between the Silver and the Copper. They are very effective anodes and cathodes in a battery, y'know. Anyway, any theories would be appreciated, as I'm growing tired of having to scrape off the flecks with a razor blade. This occurs with borth AS and AS2.

Fascinating. Make a water block out of that CVD diamond...wonder how much that would cost? I don't think I wanna know. :)

Kurt-

Hey, you could have just asked me, I would have told you what was in it and saved you all that valuable XRD time. ;-)

Really though, thanks for verifying that Arctic Silver really is what we say it is. It's nice to see good good testing, real science, and true facts in a world filled with rumor and innuendo.

Man, no one caught my math error.

I realized as I was laying down going to sleep last night, that I was a order of mag off for how many silver atoms it takes to fill a 3µm gap. Its 10710, not 1071. I totally converted from pm (bond length of silver is 228pm) and did the math for nano (not angstroms).

So the math should of been 3*10^-6/2.8^10-10, which returns 10710 atoms needed to fill the gap.

As for diamonds.... I've thought about that. One of the Ph.D.s that we just interviewed for a postion in our department does high-pressure geochemistry. She uses a diamond press - and since diamond conducts heat so well - even bringing something to the pressure of say 300km deep - it's still just warm to the touch.

But alas, cost cost and more cost. And don't metion that you don't find very many huge diamonds just laying around.

cheers!

Hey,

nice to see a fellow physician! I'm a undergraduate chemistry student in Amsterdam, the netherlands at the university of Amsterdam. XRD are nice! Your XRD is beautifull indeed, so is this whole method. Actually a nice idea to do this kind of research. I could make a NMR spectrum of water-wetter if I knew where to get this stuff in Holland. We have a Bruker 400MHz NMR over here, very clear pics! Many lower rated NMR, do you do NMR too? Maybe somewhat too organic for geologists. Your locations is not familiure to me, maybe because I'm not from the states. Where did you study?

Greetings!
