what da.... Liquid metal cooling? - Page 2

post #11 of 25
Phase cooling is already crazy, now metal cooling is BS, if it leaks, your PC blows up, bad idea I think.

No, this is the real thing. If you wiki Gallium, it will tell you this:

Gallium's high specific gravity of 5.91 gives it a volumetric heat capacity of 0.37 x 5.91 = 2.187 J/cm³, meaning that a volume of gallium will heat by 4.184/2.187 = 1.9 times more than an equal volume of water in a cooling device. However given water's benign handling characteristics and plentiful abundance in most developed countries, gallium alloys are only really likely to see use in specialised applications such as cooling supercomputers.
As when I read that, I guess'd its not a fake. A quick google and I got this, which kinda shows that its an actual product.. Neato!

That may be true but i think duckie is right in that the heat transfer medium isn't the issue...
But i think that this metal cooling could help a little, if it wasn't so expensive.

But *** is that cooling system going to do? Did you see the size of those fans? I don't care how good the liquid metal transfers heat, i highly doubt those fans can get enough heat out of the loop.

Sapphire's graphics card

An article done around the same time ... a quote from there ...
Quote:
However, the opinion of the inventor of liquid metal cooling, nanoCoolers Inc, based in Austin, Texas, is worth paying attention to. Although representatives had been very enthusiastic about the technology when I spoke to them earlier in the year, NanoCoolers removed all information about liquid metal cooling from its website in mid-July.

When I contacted a representative, a few weeks ago, he told me that nanoCoolers was shifting its focus away from liquid metal to another system, thermal electric cooling. "The market size is limited by the cost of the liquid metal solution," he said, "and we would rather get to the next stage in technology with superior cooling and the promise of a much larger market".

NanoCoolers' testing has shown liquid metal to be about five percent more effective than water cooling, and 30 percent better than an air-cooled heatpipe system.

From what I understand, at least part of the problem is this: although liquid metal might be better than anything else at sucking heat away from a hot chip, that heat doesn't magically disappear. The heat is still inside the cooling system, and must be somehow removed from the liquid metal before the coolant carries the heat back to the chip. The only way to do this is by transferring the heat to the air. And that, of course, is the same problem that old fashioned air cooling systems have. Effectively, the heat has been moved a few centimetres away from the chip, which is certainly an improvement, but it hasn't actually gone away.

Darn. I thought we could be looking at a new cooling tech in a year or so...

those things are on ebay all the time

mainly for xeons though

Must not be too great, since the company that made 'em never went to market with it and has abandoned the concept.

Hmmm...

I just want an electromagnetic pump. Iunno why. But I really want one.

This might become standard in the distant future.... VERY distant future.

Yes I agree fully.
