I must be bipolar

[Silversinksam]

Ok I decide today that I'm definitly going to keep my Radeon 8500... So I say to myself 'that ATI pathetic excuse of a heatsink's gotta go'

Talk about timing, Ian over at 2cooltek got me the Arctic Alumina Adhesive in one day(He is the man as i paid for 2 day air)

OK I took a blue orb and punched the base out of it and started to mill a new base out of silver(Took me a little while to get it perfect)Then I seated the silver base into the blue orb and used a tiny amount of Arctic Alumina adhesive to make sure there were no gaps, but the fit was tight. I drill all the holes and I was pretty stoked at having a TRUE silver orb.


Problem was I looked over on my desk and the Alpha Pal 15u was sitting there all shiny and begging me to please go on the Radeon.......But the Alpha Pal 15u just was to big.


OUT CAME THE DREMEL

I cut a two tiny one centimeter sqr cuts in a stair configuration in the Alpha's corner and it now fit perfectly on the Radeon 8500

Slapped on some copper ramsinks that I customized with 1/8" silver bases and put all of the components on with Artic Alumina adhesive(That stuff dries fast)

I took pics of the whole ordeal that I'll post tomorrow.

How much was the base?

I would believe you should have bought a copper plate and combine it with the blorb.

Hows the actual difference though?

[Silversinksam]

Silver outperforms copper and I had several plates of 4" x 12" x 3mill Silver stock, This orb is much heavier than stock.This SLORB weighs roughly 2-3 ounces, I'm pretty confident it will outperform the crystal orb, blue orb, and the orange orb.

Im going to give it to a buddy of mine for X-Mas as he is a gadget guy like me and theres nothing like getting one of a kind presents.


I got some digital pics that I'll post tomorrow as I recently reformatted and need to load the camera software.





PS If I didnt have the silver stock on hand than copper is very close in thermal properties and is definitly way cheaper.....

Remember I am SilversinkSam, not CoppersinkSam :p

[Oni]

My lord . . . You have more money in heatsinks than you do in your whole computer!! *jk*

[Silversinksam]

LOL If the recessions turns to a depression I will simply melt my heatsinks and sell the silver for food :p

Copper ramsinks with Silverbase....I got a little Adhesive on the end of the ramsink but I was tired....Ill clean that up later :beer:

The Ramsink Silver Baseplates are very thin Silverstock I had laying around approx. 1 mill thick and the Orbs Base was 3 mill's thick

I went into Bipolar mode and I figured the Alpha Pal 15u wouldnt work for this Videocard, but where theres a will theres a way...



I wanted to use all black Radio Shack Ramsinks on the bottom but thanks to a couple capacitors in the way I had to use a copper/Silver ramsink

To the Alpha Pal 15u's credit while running 3DMark2001 on the Radeon 8500 While touching the back of the GPU (back of card) I could barely feel any heat which is amazing.

Great Job on the silversinks! Make me want to do them too. Did you get the silver in a certain size as in thickness/width/length? Now I'm off to check for silver prices:eek: :beer:

[Silversinksam]

Sonny,

Thanks man, Im retired and goofing off making these oddities keeps me sane.

My ex-girlfriend is a Jewler and she gets me the Silver Stock in 12inch by 4inch by 3 mill sheets from a wholesaler in Boston.

Its extremely hard to buy Silver sheets that are close to the spot metal price.

[Sonny]

Thanks for the help. I just may take you up on "beer":D There are a few jewelers that I will check with. I got a few questions for you.

1. Have you tride making a pure silver VRAM sinks? Is it one piece or did you glue on the fins & if so with what?

2. I was thinking also of the northbridge & heatspreaders for DDR. Have you tried this?

3. Can silver be used for the CPU? How thick should the base be? 3mm or so?

4. How do I work with silver?

a. cutting
b. assembling (soldering?)

5. How do I reuse the wasted silver as in silver dust if I use a saw to cut it?

[Shadow ÒÓ]

Silversinksam also has a website full of goodies like that....what's that address again Sam?

You should at least have that in your sig!

[Silversinksam]

Shadow,

After I was forced to retire and to keep busy I started Silversink and was the first person to sell Silver coldplates in the USA.

I shut it down after many popular vendors quickly copied my idea but I still offered them cheaper than they did.

I have quietly been selling out my stock at my cost ONLY to people here at Overclockers.com

[PsYko420]

It'd be super sweet hsf if it was gold or platnum. But w/ plat your talking in the 1000's gold would be about 500 dollars.

[Silversinksam]

1. Have you tride making a pure silver VRAM sinks? Is it one piece or did you glue on the fins & if so with what?

Solid Silver as ram sinks isnt practicle for a couple reasons, first is the the Cost/Reward factor. High costs to slight improvement doesnt warrant producing them. Making Hybrids is not only cost effective but they work better

Also Silver absorbs the heat fast and I found that simple Radio shack ramsinks with a silver base actually is the best solution as the Silver base absorbs the heat and the anodized aluminum fins dissipate the heat fast.


The way I affix the silver bases is simple(I have talked to Nevin at Arctic Silver a few times to explore new solutions)

Arctic Silver Adhesive and Arctic Alumina adhesive is the way to adhere the silver bases, on large products I use tapered tiny copper screws countersunk to get the proper pressure. Arctic Alumina is especially good with ramsinks as it wont short out yor card should you accidently get the adhesive on your ram pins. KUDOS to Nevin @Arctic Silver for that!!!

Also Clamps of various sizes should be used to get the proper pressure. When Im working with Heatsinks with silver Bases I blent the ratio if the person want to be able to remove the Heatsink from the Base down the road. (THIS DOES NOT DEGRADE PERFORMANCE)

Applications like small heatsinks with silver bases on video cards can be easily removed by placing the heatsink in a freezerbag and 30 minutes in the freezer will allow you to remove the silver base. I have yet to find a Heatsink I couldnt remove with ASTA applied to it.

ALWAYS PREP THE SURFACE WITH ALCOHOL BEFORE YOU MATE THE THE HEATSINK TO THE GPU OR WHATNOT. IF DONE PROPERLY THE HEATSINK ISNT COMING OFF UNLESS YOU WANT TO GET IT OFF.


2. I was thinking also of the northbridge & heatspreaders for DDR. Have you tried this?

HEHE, My Tennmax lasagna that I use as my Northbridge cooler also has a Silver Base its the only one like it i am guessing. For DDR heatspreader 32 gauge silver would be perfect for that as the cost/weight ratio is low. I ran out of that stock but I can get more if anyone wants it.


3. Can silver be used for the CPU? How thick should the base be? 3mm or so?

Sure it can, but the closeness of copper to the thermal properties makes silver not the best in terms of cost effective solutions.....Thats why ALpha heatsinks rock as they have perfected embedding the copper in thier heatsinks. I Sold my one of a kind Swiftech Mc1001 with a Solid 3 mill Silver base to someone that had to have it. (He wants to remain annonymous until he brings it to a LAN party or something like that)


[I]4. How do I work with silver?[5. How do I reuse the wasted silver as in silver dust if I use a saw to cut it? [/B][/QUOTE]/I]


Silver is inherently a soft metal and fairly easy to work with, You can buy a jewlers saw that doesnt produce a lot of silver dust, or you can cut it with a dremmel but the amount of waste that produces makes it impracticle......(I made the Silver Orb with a Dremmel lol and I was covered in silver dust, I did have a jewlers vac that let me recycle the dust but the dust has to be seperated from the Dremmel dust. I'll let the recycler deal with that, the solid pieces of Silver that are waste I just have melted to be reused.

If you do the modding just plan it careful and think ahead and try to utilize all the silver by making a blueprint in your head of what to do.

Its a misconception that gold and platinum are good thermal conduits, Actually they suck although they are better electrical conduits. Actually a solid gold heatsink would cost you a whole lot more than $500, more like 2-5 thousand dollars depending on the size. You could probably make a small Northbridge cooler for $500 in Gold. Gold is a dense metal

[Sonny]

All I have to do now is find the silver localy & make sure I got enough money for food after I'm done;)

[Silversinksam]

Sonny,

I think your in the UK right?

Usually Jewlery Stores wont help you reasonably, look in a phone book for perhaps a jewlery training center and ask them if they can help you. Usually they have suppliers that sell silver to the students pretty cheap.

Heres another idea, Find some fine Silver scrap coins that are worn out and cheap, bring the coin/Coins to a machine shop or a metal shop and have them run the coins through a level mill and have them flattened to the thickness you want. Im sure that they wont charge you much if you tell them what they are for, they may even do it for free thinking your insane....:p

[Sonny]

Silversinksam,

LOL!!!!! Most people think I'm insane when I get behind the wheel of my car:D

I'm not from the UK. An Aunt of mine has a few friends in the jewelry business & hopefully I can take her away from her daily gambling activities to hook me up with one:)

The coins are a good idea if I can find the right size ones or my mothers silverware.J/K.

Have you seen these?(pic below) The fins are .35mm thick & a silver or copper base would take it to the next level I suppose. I just started a thread on them at the cooling forum.

[Silversinksam]

Sonny, those look like Alpha heatsinks, Alpha/Novatech is bar none the greatest manufacturer of heatsinks on planet Earth.

When they forge the heatsinks The fins and copper base are formed simultaneously under high pressure to insure metal to metal contact and minimize thermal resistance.

The main reason I didnt add that SLORB was that I just had to find a way to add my Alpha Pal 15u to the 8500. I just didnt think it could be done.

Heres a bucnh of heatsinks Alpha/Novatech HSF's

http://www.alphanovatech.com/images/top3.jpg

[Sonny]

Yup, they are the Alpha Z series. I frequent the HSF sites as of late since I've been wanting to replace my current cooler but I got to stop spending at least for this year on my puter after getting my new case, psu, cdrw & a few fans my new hobby is trashing my monthly budget:eek:

[tbirdkiri]

umm i have a thick silver bracelet i found one day.
never thought to turn it it till now but that was a few years ago.

now i need a cpu cooler the equivialant of a SK6 but without the need of a delta to get the temps i want.

i think your the man i need to talk to.

could you give me an esitmate of what it would cost?

[Silversinksam]

tbirdkiri,

I think you need a foundry as I dont cast Solid silver Heatsinks as they just aren't cost effective, but If you need help finding a foundry that will make what you want I'd be happy to help you if you email or PM me, I basicly just add silver bases to pre-exsisting Hsf's

[Oni]

Sam, how much for a Slorb and/or eight silver ramsinks?

[Silversinksam]

ONI,

Slorbs are a pain to make but if you have to have one PM me, as I make this stuff for fun and not for profit. I can make ramsinks pretty cheaply. If you have the ramsinks I can do it very reasonably but I dont use the forums for direct sales although I am clearing my silver inventory selling to you guys only at this site. I can buy any ramsinks on the market and mod them for you as well.

If you want them just PM or email me and Ill see what I can do for you.


The reason I find SLORBS to be a pain is that I dont have a round punch made and cutting it perfectly round by hand is time consuming,not to mention I end up with lots of silver waste that I have to have melted and recast...... ask me for a Square hsf mod and thats very easy to do.

[Spartacus51]

Sam,

What about silver bases on a waterblock? They worth the $$$?

[Silversinksam]

Silver or even better Cusil will slightly get you an improvement but the difference wont be earth shattering, I've never read anybody disapointed with a silver based waterblock. Unfortunatly I haven't gone to H2o cooling so Im just going by whats been written.
As you can see by the chart below the price/performance ratio makes it a difficult decision/

[Spartacus51]

Alright, if ya find out any concrete info let me know... right now I'm looking at trying to create the ultimate in total system (aren't we all, but I've had some mod ideas along with a new design for a waterblock and a couple bong ideas that could possibly all come together beatifully). Anyway I want to do it for as cheap as possible, just to prove that this all CAN be done cheap with a litle know how... If nothing else to prove to myself that know-how in the right hands will blow cash in the wrong hands out of the water.

Geeze, I'm so giddy about this whole thing I wish I could scan the images in my head and post em... lord knows I can't draw...

You forgot Cusil 5.150 W/cm-K

[Silversinksam]

Heres the list I have from MIT(I'll add cusil next time thanks to you)Cusil is good stuff if you can find it, Cusil is 72% Silver 28% Copper, I use more readily available Sterling thats 92.5% Silver 7.5% Copper in the sheets that I have. I did try to buy sheets of Cusil but it was ridiculous in price for a 12 inch by 4inch sheet at the time
