Danamics Innovates the First Liquid-metal Based CPU Cooler

Jul 18th, 2008 06:45 Discuss (46 Comments)

Here's something new: A CPU cooler that comprises of a circulatory mechanism of liquid-metal, the liquid-metal has higher thermal conductivity than other liquid media, flowing liquid metal across an array of metal fins to disperse heat, and the cycle continues. What's more, the liquid is inextinguishable. That's 'cool'. Danamics innovated such a cooler for today's CPUs called the LM10.

The cooler also has no moving parts. The pump that circulates liquid-metal across tubes doesn't have them either. The pump functions on the principles of electromagnetic flow, the ferromagnetic liquid is subjected to flow caused due to changes in polarity of electromagnets. With no moving parts, the MTBF is substantially increased. Of course, you can use a retention module of some sort to hook up a fan or two on each side of the heatsink. This product will be available soon. For more information, please visit this page.

Neat way if you run out of liquid if it is built for that. My friend dried up his liquid cooling and as a result I don't think his dual core exists anymore. I wonder what the price tag and performance is like?

EDIT: Wait a minute liquid metal????

this is very neat, but im defidently more interested in when corona fan technology will become mainstream :D
combine the two and you have a fully non-mechanicle cooling system :toast:

This has been done before. Anyone remember the liquid metal cooled X850 PE ?

If priced well, im set to be very impressed.

Edit: couldnt find article but heres a picture of it: labs.pcw.co.uk/images/cimg2035.JPG

Wow, that is quite amazing. Non moving parts = totally silent. Good ventilation in a case is the de facto standard for this type of cooler. Id get one and test it out.

I never heard of the Corona fan technology, but if you have a link to it, Id love to take a gander at it.

Who knew there were another kind of room temperature stable liquid metal out there other than mercury :wtf: Seriously, there are several hundred of them.

They're probably using NaK(sack) en.wikipedia.org/wiki/NaK

Interesting indeed - that article is 3 years old and has the same tech for a video card... but yet it never came true.

i want one of these soo bad i thought the X850XTPE blizzard was an awesome idea 3 years ago, i wish people would have jumped on this idea sooner.

Did they ever release it?

#35

mab1376

nope... it go nixed, too many problems i think.

tkpenaltyhmm with carbon nanotubes you could make a carbon nanotube based liquid metal vapour direct touch heatpipe cooler :p

Hehe, nearly the same thing I though, but not quite all that mixed up :) btw. don't the carbon nanotubes still need some TIM between cooler base and core, so add diamond paste in to the mix :p

Really hope this one comes to the market with a price tag less than a car. What happened to the OCZ Hydrojet?

jtleonWhat about the poor surface wetting...(not related to the Chamy above). Consider your childhood days playing with that liquid mercury (so much fun!). Those beads running everywhere. To effectively transfer heat, you need thorough surface wetting (easily achieved with water and common surfactants such as jet-dry, etc.)

From my feeble liquid metal experience, I don't know how the surface wetting challenge may be solved. I smell something fishy here!

LOL

easily done id guess, pack it full of liquid metal, even water will circulate when the container is @ 100% capacity all liquid will, and @ 100% capacity i see there not being any left over space lol

this is going to be much win for the silence enthusiasts.

I can see a range of them coming out, CPU, northbridge, video cards.

run em passive on the low/mid heat stuff, add a fan for epic win.

no only that but it if out performs air and water cooling then i might just be the end-all replacement if its cost effective.

personally im all about performance, if something is loud but the best performance on the market ill get that over something slightly worse and silent.

i'd probably find a way to slap 2 80mm fans on that sucker if it improves performance +5%

if this is based on the aforementioned potassium based liquid compound, i see some serious problems arising if shoddy craftsmanship is employed. One weak spot + a sudden jerky movement = flaming napalm in your PC. (Potassium is extremely reactive to oxygen [air&water]) :eek:

Right, its more likely based on a variation of Galinstan. Varying degrees of GaInSn has a lot of different uses already, so it's availiable on the market. NaK kinda died off a while ago because of this stuff. The only downside to it, is that it still eats through aluminum, so you'll be stuck with steel heatpipes. I've see combinations of GaInSn with a thermal conductivity of up to 80 W/mK

NaK is indeed terribly dangerous because of the potassium. I wouldn't want any of that in my rig for the life of me. We're going to have to find the details of this thing.
If I remember correctly, galinstan is used in medical grade thermometers. I've seen the stuff rip through an aluminum bar that was a supportive piece in a benching rig of my friend.
Steel would work but it would only make the thing more costly to produce. I guess they already worked it but I still want to know what they're using.

why not use copper? I know there was a liquid metal TIM that ate through aluminum but left copper alone.

Wait a min...thats a magnetic pump!

OK Gurus...is NaK or galinstan offer any ferritic pumping capability? How does a magnet move non-ferritic metals?

you are asking tough questions. my answer would be 'magic; :D

Magic is bad :D I was just hoping the crap wasn't lead-based, that's all :p But we know it definitely is :(
Lead can maintain a solid form at room temp & liquify when heat is applied.
That way, they can use their cheapo aluminum or copper heatpipes.
Those babies better have some kickass welding going on :laugh:
