925 - Solid Sterling Silver

I am not a scientist nor an engineer by trade but I am a jeweler and I have been toying with the idea of building a silver heat sink for my system. I have done plenty of computer builds and am an avid fan of air cooling (pun intended), so I wanted to step up the game a bit and put some high performance materials to work. For years I Have been well aware that silver conducts heat at a remarkable rate. In my trade its a known fact and a bit of a complication when conducting repairs, I have seen some numbers related to this but the honest truth is if I handed you a 10 foot long peace of silver wire and put my torch to one end and your hand at another, you will drop it in seconds, that's all the information I need to sell my on this idea.

I was wondering if any one else has built such a heat sink?

925 is the stamp for silver, it stands for 925 parts per thousand, or rather the purity of the stock. most silver is alloyed with copper (The Sterling mix to be exact) so I am not to worried about getting "Supper ubuurzorz crazy pure silver" since copper is almost as effective of a conductor.

Should I mimic another design? should the fins be brush/sandblasted/pitted, or high polish? (I'm assuming a brush/sanded)
note: I can just about finish the fins with any desired pattern.

Should I remove the stock heat spreader off the CPU and replace it with a silver one?

(I know the base should be high polished)

Whats more important, Fin surface area, Mass, fin length(Distance from Base to tip)

I am going to stick with a welded/soldered fabrication method since I have noticed over the years that cast peaces have weaker thermal property's then forged/rolled/hammered. (this could be in my head)

Lastly, should I factor in air flow as a primary design driver or a minor factor IE: Avoid turbulence? encourage it? or just ignore it and go for maximum mass/surface area.

All joints will be Laser welded and or solder with plum high temp silver weld solder.

I don't know if I'll be too much help but I'll give my support and pose a question: Heat pipes possible? And good luck

.

Edit: Or maybe a silver waterblock....hrmmm

Make an all silver TRUE. With more heatpipes.

The heatpipes are going to be the hardest part.... You can order them but they are expensive for individual ones.

(Silver waterblocks are easier

)

This would be crazy..although i think it would be easier to make a silver waterblock..but alot more expensive.

Oh wow... Try to follow designs of good performing HSFs (true, dark knight, etc..)

Hasn't it been proven that even on water silver only nets about 2c difference? I can't see tripling the cost (or more) to net 2c.

Granted, the E-peen value would be huge.

Cost isnt an issue I have the stock collecting dust at the shop and I would rather turn 200$ (whole sale cost) worth of silver into a shiny heat sink then scrap it.

silver waterblock would be a much easier thing to do, plus you could launch yourself into a new addictio... I mean hobby, water cooling!

Then make a silver case
