Danamics - a revolutionary cooling system?!

Problem I see with it is how will it be cooled, even water needs a fan and it doesn't look like a fan would would hit but 1 heatpipe.

Err... The fins cool the pipes. ;)

This thing uses an EM pump, right?

yea which means it should be capable of high flow rates

heat conducted at contact area, transported to radiator, heat released.

water itself isn't much of a heat conductor so it requires pumping n stuff.

same goes for air. needs a lot of flow to be effective.

This is right around the corner,

can't this be done with some kinda Oil ? (expamle canola oil) be much cheaper.

As other posters have said, it has long been known that liquid metal is both possible to use and indeed has been used in a variety of VGA coolers... but the issues of cost and quality are large. So in regards to this, I'll remain skeptical.


There was a member of these forums who a set of CPU coolers pulled from some military computers who might be able to add some fun info. iirc, it was basically a water loop, but used a liquid gallium/tin alloy. Here's the link, for anyone whose interested that may not have been around at the time:

Talk about being ahead of there time, check out these links to the company that made that gallium liquid xeon loop on our tax dollars.

EM pump

Haha, Tardbus is already doing Liquid Gallium cooling here: http://www.xtremesystems.org/forums/...ad.php?t=99240

"An electromagnetic pump has several advantages over typical mechanical pump designs. It contains no moving parts, shafts, seals, etc., emits no noise or vibration, has unlimited MTBF and suffers no performance degrading over time"

it's moving by heat.

No, that would be convection.
Neither does this use a traditional electromagnetic pump. Or at least, if it does it's lying about the 'moving parts' thing. a traditional electromagnetic pump manipulates a piston using a solenoid type em field. a typical em pump has a cycle of 50hz, which is why i say flow rates here could be incredible.
but for this application an actual EM pump in the traditional sense would be useles. An EM pump could be used in any fluid application, but the danamics lm10 happens to be moving liquid metal.

that would be convection, a little bit like traditional heatpipes. i don't know how an EM pump works but i made a rough guess that a metal fluid was needed for it to work because it's easily polarised.. could be wrong.

Soviet Russia used liquid metals to transfer heat from their submarine nuclear reactors. It did not go so well. Hopefully these guys have learned from their mistakes.

PS: This comment was meant to be funny. If you do not have a background in Cold War Soviet Nuclear Reactor design then this joke has probably been lost on you. Use Google and learn.

This is actually pretty interesting. Do you have an article handy?

Eh? Last I heard, I thought the type of pump used was where they passed a current through the liquid metal using a U shaped dongle and that generated a lorentz force.

Well, if you had a ferromagnetic coolant, you could pump it by alternating the field on a couple electromagnets. Much like a Japanese bullet train can be moved by rapidly alternating, albeit static, electromagnets.

I paid about the same for my current watercooling setup, but a single cooler with the same or better perfromance is worth it imo.

$399 usd.

Well, it is technically a double pass radiator. Now we have to see if it is capable of dissipating as much heat as a 120.3 or something..

ROFL ROFL ROFL
at the RRP :rolleyes:

lol of course its not, unless you compare 120.3 with ultra quiet fans Vs this sucker with couple of deltas :D

That's the thing - I'm pretty sure it's been incontrovertibly shown that it could not be better, or really even somewhat similar.


What it boils down to: There is only one fan removing heat and has a limited amount of surface area. We've gone into more detail on the ability of the pump elsewhere, but the previous sentence is going to be a huge reason why this couldn't be better than water cooling.
