Danamics - a revolutionary cooling system?!

[cegras]

If the metal is liquid, it does not matter that much how well it conducts. Even if it were to conduct as well as copper, thats still pretty slow. (Have you ever held a copper bar on one end and heated the other?)

Having a higher heat capacity is better, because then it takes a lot more heat energy to heat up the water per degree, which is what you want in a waterblock.

The only reason i can think of for using liquid metal is to use a magnetic pump, so they don't have to rely on moving parts

I don't think you understand. The rate of heat transfer at the contact point of the liquid metal to the cold plate would be much much quicker than if you used water as the working fluid.

Also, I think the effectiveness of a conductor changes as it changes phase. I'm not sure if it goes up or down, though.

There is no Brownian motion in a solid copper bar as there is in water, that is why there is the illusion of the water conducting the heat faster than the copper. however once the metal is liquid, particle theory comes into play and the actual molecules that are hot can move about instead of molecules relaying the heat across each other.

Never-the-less, this will be quite interesting. I say, bring it on!

You definitely want both a good thermal conductivity and specific heat capacity. Ultimately, though, you could get away with both a low conductivity and capacity; you'd just have to pump your coolant at a greater rate. I mean, this principle works for air. Air's heat conductivity sucks, and heat capacity is even worse, so you just need a lot of it to compensate. Fortunately, it's very easy to pump air.

So yeah, you could get away with a coolant that really sucks in both categories. Of course, if you use something with very high conductivity and capacity, for example liquid hydrogen, the big win is that you don't have to pump it very fast.

Edit: I don't know Gallium's thermal conductivity offhand, but I know that most metals are at least 3 orders of magnitude above water... so it's significantly better, most likely. However, they won't have the same capacity as water, so you win some, you lose some.

Edit2: the main wins here are that: 1) it will not tend to evaporate and create very high pressures in a sealed loop, and 2) it can be pumped with a solid-state pump.

Edit3: Actually, I don't know how a liquid state would affect thermal conductivity for metals. For instance, Water is ~0.6 while Ice is ~2.0 W/(m*K). Anyway, who cares? I've already pointed out that you can get away with sucking at both conductivity and capacity.

Got an update from Danamics this morning regarding the cooler... they have updated their website with more information and also provided me with this handy picture for you all

[Hornet331]

hmm low surface area, i doubt that thing cools better then a IFX-14/orochi, since the limiting factor will be the heat transfer to the air....

also im sure this cooler needs a high preasure fan to show its potential.

Looks like it was subcontracted out to Thermalright for the fin construction.

Lets just hope the base has a better finish than the one on the TRUE.

This is not the image I had in my head at all. lol

Our launch of LM10 is expected to be in late Q3, so we should be getting close.

[chunkylover77]

Spawne will you be getting one early to test?

[NH|Delph1]

Argh, shipping is slow

a mini break down on the cooler, but I want to see numbers

[dunn2953]

but will it kill john connor?

[Spawne32]

They told me they will notify me when the samples are ready

[CarpeDiem]

Wow sweet, they say it's better than most water cooling systems! Put me down for two!

[MnM]

Yeah put me down for an independent review too ...

[RealTelstar]

Ask them for a review sample, i think they are willing to, or so they say on the website.

It doesn't have to be completely metal to work though does it? Couldn't it be metal particles in a suspension. This would be relatively safe and cheap. Moving the metal particles with a magnetic field should move the liquid medium along with it. In fact, if they're going to use an electromagnetic pump, would the main metal have to be iron?

I just wonder how much of a pressure increase there is from room temperature to say 70C. Unless the liquid is completely non-volatile up to that temp, there's got to be some increase. If so and if it's not extremely well made, you'll eventually get some stress fractures and then you can kiss your mobo and cpu goodbye.

Metal particles in suspension work well in laminar flow systems but do not help in turbulent flow. Pressure is not an issue if you have air at the top of the reservoir to compress.

The cooler looks pretty big and echos the TRUE:

This looks interesting, I can't wait to see results if this is true.

[purecain]

what an amazingly innovative product... i'd like to try one just out of interest....

[Okda]

looking fwd for the retail product

[saveus222]

wow. liquid metal.. sounds scary for some reason.. and dam expensive..so it shld be coming under water cooling ? ok sorry liquid cooling ?

apparently the performance is supposed to match that of water cooling, same concept, just liquid metal vs water, and a much smaller loop :P But will be interesting, if it can come close to water. I m excited to say the least, as long as it doesn't cost the same as a good water setup :P
