Is Your Silver-based Thermal Paste Really Silver?

strider69666 writes "Over at Overclockers.com they have a review of several thermal compounds that claim to have 99% pure silver content. 'I decided to test Arctic Silver 5, Arctic Silver 3, OCZ Ultra II Premium Silver Compound, and CompUSA Silver Thermal Grease. This test was not conducted to test performance, but rather to determine if these compounds have Silver as an ingredient.' Using a professionally mixed testing solution, they found that several brands do not, in fact, contain any silver at all! So, are you getting what you are paying for?"

I prefer the Better Business Bureau. I've filed a few complaints, and so far I've always gotten results.

OCZ has announced a recall. (5, Informative)

DAldredge (2353) | more than 10 years ago | (#8063451)

http://www.ocztechnology.com/displaypage.php?name= recall

From the above site:

OCZ would like to take this time to address the recent article published at Overclockers.com, ( http://www.overclockers.com/articles938/ )which shows that OCZ Ultra 2 thermal compound has no silver content.

OCZ does not manufacture Ultra 2 thermal compound in house, it is provided by a foreign manufacturer with our specifications. Previous independent lab tests conducted at the request of OCZ have shown that the silver compound content in Ultra 2 is 25% by volume and 70% by weight.

In response to this article, OCZ has submitted another batch of Ultra 2 to a third party for extensive lab testing. This Independent lab report show's that the most recent batch of OCZ Ultra 2 indeed contains less than 1% silver by volume. While simultaneously we have received lab reports from an outside source indicating the silver content to be 30% by weight. This leads us to the conclusion that recent batch(s) of OCZ Ultra 2 from our supplier did not meet the agreed specifications.

We accept full responsibility for these problems and we will be seeking legal action against our supplier.

In order to help solve this problem we have contacted Arctic Silver Inc, and entered into a vendor agreement with them to supply OCZ thermal paste.

Beginning January 22nd 2004 we are issuing a full recall of any and all OCZ Ultra 2.

Any Customers who wish to return OCZ Ultra 2 thermal paste with an invoice will in exchange for their full or partially used tube(s) receive:
1- One (dependant on # of tubes returned) 3-gram OCZ thermal Compound (made by Arctic Silver Inc.) or one OCZ Dominator 2 Heatsink.
2- One OCZ EL DDR T-Shirt
3- One 10 dollar off rebate on any OCZ EL DDR Dual Channel Kit (at participating resellers)

So is "silver" even a necessity to CPU cooling? If people are purchasing this compound because it is "99% silver" and place it inbetween the CPU and the heatsink, isn't there more at stake here? I mean what if there were damaged CPUs due to the usage of this compound instead of one with 99% silver? Shouldn't they be paying for more than just re-emburse you for your bunk tube you paid for? What about the bunk CPU that it fried?

Cost of Silver? Copper an alternative? (1, Interesting)

green pizza (159161) | more than 10 years ago | (#8063454)

Is silver so expensive that these compaines have no way of adding silver to the paste? What made them think nobody would ever put their pastes to the test?

IIRC, copper conducts heat better than silver... why not make a copper paste, surly it would be much cheaper to make. Or would the companies use copper-colored pigment and lie to us about the copper too?

Re:Cost of Silver? Copper an alternative? (3, Interesting)

DAldredge (2353) | more than 10 years ago | (#8063474)

Doesn't aluminum also conduct near as well as silver? could it be used in a paste for a fraction of a cost?

I know I've used aluminum foil between a heatsink and CPU before, and it's worked just as well for keeping the CPU temperature down as any thermal paste.

Re:Cost of Silver? Copper an alternative? (0)

Anonymous Coward | more than 10 years ago | (#8063556)

Actually a friend of mine who works for an electronics shop told me why this doesn't work, but it involves some kind of dielectric difference between the aluminum and the copper on the bottom of the heatsink.

What it results in is a CPU that is actually at the temperature as if you'd used a good thermal paste, but it's really running hotter.

That's where I buy all my thermal paste, and they haven't steered me wrong yet

Heat sinks are made of aluminum, which tells me that aluminum has the best heat conductivity to cost ratio. why don't they use aluminum?

TelcusFreshbreeze (601347) | more than 10 years ago | (#8063569)

Heat sinks are made of aluminum The better heat sinks out there are actually made of copper, as the grandparent poster surmised.

Check out some of the heatsink companies websites, thermaltake etc, to get some graphs and such about the heating properties of their products.

Toms [tomshardware.com] does regular heatsink comparisons, and the copper always beats out the alu of the same type.

Re:Cost of Silver? Copper an alternative? (1)

saiha (665337) | more than 10 years ago | (#8063598)

Well harddrives probably have the best storage to cost ratio (well tapes, etc but those aren't random access) so should they be used instead of on die caches? The point of using high quality conductors for the thermal paste is that you don't need very much of it to be effective, therefore you can use much higher cost components/materials.

However you can actually get an aluminum based thermal compound for about half the cost of a silver based compound. In fact because the paste has to only act as the link between the die and the heatsink as long as the compound is applied correctly and it has good thermal properties, only overclockers could probably tell the difference.

GoRK (10018) | more than 10 years ago | (#8063599)

Actually no. Gold has the highest thermal and electrical conductivity of the natural, elemental metals, however the cost difference when you need a large chunk of it is fairly sizeable.

Diamond and other carbon structures hold the promise for better (semi-conductivity) and thermal transfer on the small scale, but at this point they are quite a bit more difficult to work with than the "traditional" materials.

Re:Cost of Silver? Copper an alternative? (1)

kinema (630983) | more than 10 years ago | (#8063575)

IIRC, copper conducts heat better than silver...
Actuall silver is a better conductor of heat. Silver has a conductivity 428 W/m*K compared to copper's 398 W/m*K. Diamond is the best known conductor IIRC with a theoretical conductivity of 2500 W/m*K for a perfectly formed flawless diamond.

Re: Silver is better than copper or aluminum (5, Informative)

MachDelta (704883) | more than 10 years ago | (#8063622)

Actually, silver is a better thermal conductor than copper or aluminum. IIRC, it goes:

(In Watts per meter per degree Kelvin)
Silver ~420 W/mK
Pure Copper ~400 W/mK)
Pure Aluminum ~240 W/mK)

If you REALLY wanted some fancy shit, try a diamond paste. Diamond is like 2000+ W/mK. Really good at transfering heat. (No, I don't know if anyone actually makes the stuff).
Oh, and just for reference, air is about 0.025 w/mK, and water is somewhere around 0.6ish.

So you could use a copper paste, but it wouldn't be quite as good as the Silver.

Try searching for "ocz ultra premium silver" on Froogle [google.com] . This is the first link. [ncix.com] It clearly states Made with 99.9% pure micronized silver and Over 70% silver content by weight. When they're emphasizing "silver" all the time, what do you think Marketing is trying to tell you? That's right, they want you to buy their garbage because it's got a cool silver crud in the product, not because it looks silverish.

Well, too much in your system can turn you blue. Do a google search on Colloidal Silver.

Medicinal silver is most often sold as colloidal silver protein (CSP). In a recent case report, a 56-year-old man noticed a blue discoloration under his fingernails.1 He had been taking CSP supplements daily for 3 years, in hopes of preventing colds and allergies. The diagnosis was argyria, a blue-black tinting of the skin and mucous membranes caused by a build-up of silver. Numerous similar cases have been reported in recent years.2,3
In argyria, silver deposited in the body reacts with the sun through a process similar to that of the development of a photographic negative. This leads to permanent discoloration of the skin. Changes may be seen in the eyes, lips, and nose as well.
The condition was even more common in decades past, when CSP was an accepted medical treatment. Fortunately, argyria is seldom dangerous, although in some cases nerve damage may occur.

It is silver. Don't forget, silver is a not only an element on the periodic table, but a color. Just like some of the 'copper' heatsinks are nothing more than gold colored cheaper metals. If it were real silver, and cost $.99 a tube, I'd make a killing on the commodities market. I'd bet a pile of 'gold' that's the excuse.

I know you're joking but still. I have to correct. The "french" in "french fries" refers to the process of "frenching"--that is, the method by which they are cut. They would be more accurately described as "frenched fries." I know. Off my soapbox now. ;)

Yeah, well, would you buy "Dr. Prune"?

Yeah and remind me to sue crayola too for not including any real silver in their silver crayons, those damned cheapskates.

The silver crayons don't claim to have 99% silver contained in them. The compusa compound and the ocz compound claimed they did.

thats why i cant get silver Crayola here. OCZ's supplier bought the whole lot and created their thermal paste.

so i assume the OCZ product is just paste. i guess it'll still be good so that your fan wont fall off the processor. :)

You're telling me a site on overclocking [overclockers.com] has to cut off the user limit? Their servers aren't overclocked enough to handle it?

Please, actually think about what you say... (5, Informative)

Comp USA brand silver thermal grease is, indeed, marketed as having silver content. Not just silver coloring, but, explicitly, silver content. Take a look at this before they take it down: compusa.com Product Listing [compusa.com] .

In addition, the author claims that similar claims were made on the label of OCZ paste. Judging by the reaction from the people at OCZ (or the people that claim to be OCZ) and his accuracy in the rest of the test, I have no reason to doubt him.

Please, think before you spout the tired, cynical rhetoric about shady advertisement.

Surface tension (2, Insightful)

Explodo (743412) | more than 10 years ago | (#8063548)

Does anyone else notice that the two tests that showed positive have let the drop of test solution spread out? Does the fact that the two that tested negative have the solution beaded up indicate very little interaction between the two substances? Where's a chemist on this? It doesn't look like they're mixing...

"SILVER THERMAL PASTES - BUYERS BEWARE!"
Silversinksam - 1/21/04

I decided to test Arctic Silver 5, Arctic Silver 3, OCZ Ultra II Premium Silver Compound, and CompUSA Silver Thermal Grease. This test was not conducted to test performance, but rather to determine if these compounds have Silver as an ingredient.

All Testing was done twice, once on a jeweler's acid free 'Black stone', and the test was repeated on paper. The testing solution was Nitric acid and Muriatic acid that was pre-mixed professionally.

The tests produced some very disturbing results:

OCZ Ultra II Premium Silver compound and the CompUSA Silver Thermal Grease has ZERO silver in it.

The testing solution stayed orange - if it had any silver in it, the acids would turn varying degrees of red, depending on the purity of the silver present. OCZ claims that OCZ Ultra II Premium Silver compound is, "Made with 99.9% pure micronized silver, Over 70% silver content by weight".

I cannot concur and my tests conclusively show that there is Zero micronized silver present, and Zero silver content by weight.

Arctic Silver 3 and Arctic Silver 5 were also tested and both produced a blood red color, indicating 90% - 100% purity of Silver in both Arctic Silver 3 and Arctic Silver 5. Arctic Silver's claim of, "Contains 99.9% pure silver" by my testing is accurate and of the compounds tested, only Arctic Silver products produced results showing that Silver is in fact present.

The tubes in the picture below from left to right, Arctic Silver 5, Arctic Silver 3, OCZ Ultra II Premium Silver Compound and CompUSA Silver Thermal Grease.

In picture 3 below, from left to right is Arctic Silver 5, Arctic Silver 3 and OCZ Ultra II Premium Silver Compound. The compounds were placed on the paper and the acid was place on the compound undisturbed. Notice how the acid drop placed on the OCZ Ultra II Premium Silver Compound remains orange, indicating zero silver present:

When you go into a jewelry store and buy a sterling silver or a fine silver necklace, you expect the jewelry to be made of sterling or fine silver. The same should apply to silver thermal pastes - if the silver paste has no silver in it and the manufacturer says it does, that is misleading.

Based on my testing, I can not recommend OCZ Ultra II Premium Silver Compound or CompUSA Silver Thermal Grease, as they are both misleading products with zero silver in them. If you want a product that actually has silver as an ingredient, Arctic Silver 3, Arctic Silver 5 or Arctic Silver Adhesive tested OK.

Ed Note: Silversinksam's conclusions have been verified by an independent testing laboratory - details will follow in Part 2 of this article.

Ah, memories of chemistry class (2, Interesting)

fatalist23 (534463) | more than 10 years ago | (#8063589)

When I read the above post, the first thing into my head was high school chemistry class and trying to get silver to precipitate... Much to my dismay, the article writer has chosen the easy way out with some color changing liquid which tells you when it's reacting with silver.

I was looking forward to poking fun at his titration technique... I mean, it was hellish trying to get as much precipitate as "expected" in those godamn experiments.

Overclocking not for the serious geek (4, Insightful)

Haxx (314221) | more than 10 years ago | (#8063595)

The overclocking thing bewilders me. These overclockers only push there cpu's to the limit so they can see a performance gain in the latest version of Quake.

You can't overclock a cpu on a pc or a server that has any real use what-so-ever.

Imagine overclocking the cpu on you employers mail server, then it becomes unstable and corrupts half the data!

OCZ Recall (1)

doormat (63648) | more than 10 years ago | (#8063611)

And to make up for not having the advertised amount of silver in their thermal compound, OCZ announced a recall [ocztechnology.com] .
