DIY CPU Thermal Grease, Using Diamond Dust

timothy posted more than 5 years ago | from the honey-about-the-ring-you-used-to-have dept.

Hardware Hacking 210

tygerstripes writes "The dysfunctor has spotted an impressive project over on InventGeek.com; an innovative chap has developed his own thermal compound for improved CPU cooling, using diamond dust — the best available material for thermal conduction — as the key ingredient. In spite of the quick-&-dirty DIY nature of the project, the gains in cooling performance are remarkable, especially considering the material cost was only $33. Given the price many enthusiasts will pay for a top-end cooler, it's easy to imagine this product coming to market quite soon."

Beyond the poor-quality natural stones(which are a modestly abundant byproduct of mining for the good stuff) synthesizing industrial grit size/quality diamonds is now well within the realm of doable. Large/Gem quality ones are either available or in the "real soon now" stage(producers of the natural ones are Not Happy with this...)

Re:Diamond dust is cheap? (5, Insightful)

jandrese (485) | more than 5 years ago | (#28962323)

Diamonds aren't even rare, the only reason they're expensive is because they're produced by cartels that that are more than willing pull underhanded tricks to crush the competition. Granted, really large gem quality diamonds aren't enormously abundant, but the prices on them are definitely inflated.

I think you've completely failed to understand the gemstone, precious metal, and jewelry markets. As the son of (and apprentice to) a GIA certified gemologist and master goldsmith; I'm curious who you think is behind the manipulation specifically regarding diamonds. The GIA? The EGL? The IGI?

When Russia entered the market. See http://en.wikipedia.org/wiki/Diamond [wikipedia.org] And read under "Mining, sources and production" for most of it. It doesn't due justice to how that market opening up lowered prices

But really there are 6 major players now, not just one. However De Beers still is nearly 40% of the market.

I for one would love to see diamonds become as common and cheap as catseyes or obsidian so that it can be used more for its non jewel properties more.

Re:Diamond dust is cheap? (4, Informative)

Demonantis (1340557) | more than 5 years ago | (#28961337)

Large non occluded diamonds are really expensive. The cost then exponentially decreases as size and transparency decrease. As well, small dark diamonds can be manufactured in a lab easily. These two factors lead to diamond dust being extremely cheap compared to its cousins in jewelry.

Re:Diamond dust is cheap? (-1, Redundant)

Anonymous Coward | more than 5 years ago | (#28961373)

Small (synthetic) diamonds are an industrial product. They're used for cutting, drilling, grinding, and polishing, where their hardness and excellent thermal conductivity is important.

Enleth (947766) | more than 5 years ago | (#28961485)

Nope. Jewellery is nowadays just a little part of the worldwide diamond industry, and while it often uses natural, mined diamonds (mainly because some weird people with bucketloads of cash want to be sure that the diamond they wear is natural and mined, even though it is perfectly possible to produce a diamond of equal aesthetic value in a lab), which are quite expensive, the biggest demand for diamonds is in the tools industry. Most of it goes into production of diamond-tipped cutting tools (which are actually coated in diamond powder or small diamond shards, not made of solid crystal) for the market, the rest is used to make specialized cutting and grinding elements in machines that produce solid carbide tools.

Just check eBay or your local hardware store for the prices of diamond-tipped tools - they're only about twice as expensive as high-quality HSS and often cheaper than good solid carbide cutters, because they're actually just HSS with some diamond powder coating, easy and quick to produce.

It's actually not any cheaper to make an F,FL-IS 1 carat jewel (~2 carat seed stone) then it is to mine it, especially since a lot of the value is in the labor to cut it perfectly.

I'm gonna throw out a spoiler: In a test situation, at full load, the best temperature under Arctic Silver was 57C, while this diamond dust compound achieved 38C. The nearly 20 degree difference is huge, and would definitely make a difference in overclocking. I'm hoping the price can come down when produced in industrial quantities, because it'll be enormously worthwhile.

Judging by the massive amount of incorrectly applied compound I see in their pictures then I'm not sure if we can trust their numbers.

maxume (22995) | more than 5 years ago | (#28961747)

It looks like $15 worth would be plenty for a single CPU, if you are bothering with overclocking, I would think that is peanuts.

It also looks like his thin layer is awful thick (but I don't spend a lot of time overclocking, I just understand that the point of the thermal grease is only to fill voids, direct contact is preferable), so it might cost even less.

blair1q (305137) | more than 5 years ago | (#28961809)

The thermal conductivity of Arctic Silver and this stuff couldn't be so great that a layer as thin as the crack-filler between a chip lid and a cooling-fin plate would amount to a 19C difference in temperature.

I want to see independent reproduction of the experiment.

Either it's totally bogus, or something was not installed correctly in one of the two setups. The heat sink on the 57C, or the thermometer on the 38C.

Re:bottom line (3, Insightful)

billcopc (196330) | more than 5 years ago | (#28962335)

The nearly 20'C difference is too much to be true. In particular, there is no mention of the ambient room temperature, and since the tests were performed on different days, it is a pretty important discrepancy.

Had the tests all been performed in quick succession, the results would be far more representative. For all we know, the Arctic Silver measurement may have been taken in the summer, inside a closed and poorly chassis while dinner was cooking, while the diamond measurement might have been taken in the middle of winter with the window open.

Pulling numbers out of my ass, I would realistically expect no more than a 4-5'C improvement with diamond paste over the regular stuff.

This technology is not new. Diamonds have been used as heat sinks and thermal conductors for processors in sattelites since the 70s (natural diamonds in big sizes, so expensive). Since about 1992 there have been succesful efforts to sinter diamond dust (waste material from the polishing process of gemstones, and now increasingly synthethic diamonds, both are not expensive) for use in thermal conductors.

As far as just hoping on Ebay and buying your own, good luck. Finding a distributor for your dust and suspension will take you some time.

I think the most important thing people should consider and hasn't been mentioned so far is that the equation for heat transport is linear. Changing the adulterant in the suspension will be more noticeable as the temp increases. IMHO for most people it's a total waste of materials, for some people it's a decent alternative, and for a very small number of people it's a good idea to spend the time locating materials to make a batch.

People also keep forgetting that they're using passive cooling too so even if they get the most badass water-cooling rig with a dog sized radiator and 12 delta screamer fans they're still not getting below ambient.

$33? You can buy a tube of IC Diamond for only $7. DIY isn't too interesting when it costs so much more than off-the-shelf...

It says 7 carat for IC Diamond. Didn't the article mention 28 carats and much higher gain? Or does the 7 carat mean 7 carat after mixing it with the other components?

Since no one reads the article and seems more interested in whining about diamond prices, here are the improvements that were achieved with the new thermal paste.

Idle - Max load
42c - 57c - Arctic Silver with a fresh application
39c - 54c - Arctic Silver with 2 week cure
29c - 38c - Diamond Grease with a fresh application

These numbers are almost too good to be true. A 19c drop under load with diamond paste? With my 4GHz OC'd system, I'm happy getting 38c when idling. If this data is true, it will really be revolutionary.

Since no one reads the article

Don't you mean, er, "artical"? I suppose it smacks of me being a spelling nazi, but it makes a site's already too-good-to-be-true claims sound even less valid when the first thing I see on the main page is "Featured Artical", and then realize the same typo is made in equally large text partway down the page.

It's like when someone insists they're an expert on computers and then says that they bought a Jesus (as in "Hay-Soos") EeePC.

So you are saying that this plea from the InventGeek site didn't make you want to donate:

But we alwase can use some help funding new projects for you all. So please donate!

*mind boggles* This is game changing. 19C reduction is bigger than the difference between a stock intel crappy cooler and a $100 aftermarket tower cooler!

A lapped heatsink base, match-lapped to the heatspreader took me from 60C to 55C under load. I thought that was a epic reduction for 40 minutes work.

I wonder how this would work with carefully lapped heatspreader, even bigger reductions?

I feel like there is an Arrested Development joke somewhere in here.

Lindsay:
There's a cream with real diamonds in it. I can actually smear diamonds on my face! And it's only $400 a tub! That's, like, what, like, a million diamonds for $400? A million bleeping diamonds!

Diamond coated razor blades (1)

Twinbee (767046) | more than 5 years ago | (#28962557)

While we're on this topic, why don't razor blade manufacturers use diamond dust/shards for the tips of the shaver blades?

I'm sure some will be thinking 'conspiracy' so joe punter has to buy more, but I'm hoping there's a more rational explanation.
