passive liquid cooling! (whaaaaaaaat?!)

I guess its not really "new" news but I feel the need to share this because its so cool.

Text from the article:

SilverStone has demonstrated at Computex 2013 a new concept liquid-cooler technology that requires no pump to propel the liquid, making it completely passive. 

Like with heatpipes, the cooler uses the principle of harnessing the evaporation and condensation properties of a non-water liquid to circulate that same liquid. As the liquid is warmed it evaporates and creates pressure. By making one pipe to the radiator narrower than the other and mounting the CPU block vertically the pressure difference forces the liquid to start circulating through the system. As the temperature increases the liquid circulates even faster.

It's an ingenious idea that, assuming the radiator is cooled passively, allows for a system with no moving parts. 

There are, however, a few issues. One is that the liquid simply doesn't start pumping itself until it reaches around 30-40 degrees, which means it doesn't actually cool any more effectively than many an air or water cooler. When under load it is also likely the radiator would require fans to keep it dissipating the heat sufficiently. As such the whole passive argument goes somewhat out the window. 

All told, although SilverStone is still testing to see whether this can be a viable product, in all likeliness it will never make it to market and is more of a neat trick than anything else. But who doesn't like a neat trick.

This is ANCIENT news. Why post it?

This is a repost from a year ago.

I'm waiting for this to get properly implemented since the first day i saw it...

 

As a chemist I'm still curious what fluid is inside there.

 

I hope they will perform similarly as a dual tower air cooler.

1. this is old news

2. its not passive if requires moving parts and this does

3M Novec. It's not that great, but it'll do the job for an 80W CPU and below if you don't overclock.

make the rad the size of the side of your case?

Probs acetone

 

Seeing as it won't degrade and it's got a low boiling point

"3M Novec". I hate those marketing terms. It seems to be a perfluorated ketone, which is of course very stable towards igniting, electric dischrage etc. but still has a low boiling point. I guessed something in that direction, but it's nice to know.

Flamable and teratogenic. Probably not, but pretty similar, see post above.

 

Edit: and acetone is too agressive on the PCB imo.

They use Acetone in heatpipes, which is basically what this is except rather than a wick, it uses a return pipe.

[patrickjp93]

I think it would be better if you insulated the area around the CPU and used a Peltier mat/plate inside the liquid. Greater surface area for heat dissipation and MUCH better temps. Doesn't even require much electricity.

Nope, the stuff in heatpipes is almost allways comrpessed amonia gas. Has a legendary heat conductivity for the money.

[Trik'Stari]

Neat.

He said this atrocity on the WAN show back in the days that it used to be called the live stream, damn him; we'll never find it now.

Oh wow. That was some time ago. Even i don't remember it. nvm then.

Well I doubt it since they are only 1-5 Degrees worse than a non passive AIO 240mm Rad. 

[Octagoncow]

And here I thought we were getting an update on this... I still think this is a pretty cool idea,but really wonder if it will ever be marketable since it seems to need pretty specific conditions for it to work properly.

Because its cool. If i haven't hear about it until now im sure its news to some other people as well.

It says in the article if you don't use fans then there are no moving parts. The radiator could be used as a passive radiator.

How is it news if it's from over a year ago though? Surly it would be best to post it in the general discussion section instead.

"When under load it is also likely the radiator would require fans to keep it dissipating the heat sufficiently. As such the whole passive argument goes somewhat out the window."

That's a quote from the article, also also if you don't use fans there may not be any moving parts however it will overheat as soon as any load is put on it.

If you have to include "at Computex 2013" then it's old news.
