- JohnnyXmas, on 06/06/2008, -1/+13IBM seems to be all about cooling lately. ice to see them putting all of that money to good use.
- Arramol, on 06/06/2008, -1/+12Can we cool it with the puns, people?
- zspade, on 06/06/2008, -0/+9This is going to allow for 3d chips, that means cube processors rather than our flat rectangle processors now, and yes that really does equal a whole lot more power. The thing that has been stopping us up to this point has been heat, and IBM is trying to overcome that. If you're not impressed, you don't understand the implications of this research.
- naner, on 06/06/2008, -0/+9Correct me if I'm wrong, but from what I remember from my old physics courses, pure water isn't all that conductive. As soon as you introduce impurities (salt, for example), it starts to become a much better conductor.
- Kallstar, on 06/06/2008, -1/+8Stop giving people the cold shoulder. You need to chill out.
- send9, on 06/06/2008, -0/+7Maybe you don't understand how conventional water cooling works, but this is talking about running water through the chip, not merely on top of it, as an add-on.
- JohnnyXmas, on 06/06/2008, -1/+8Dude, why are you NOT using FireFox's NoScript plugin? It disables ALL of that crap.
- inactive, on 06/06/2008, -0/+5Not on ebay yet.
Damn, - FeargusMcDuff, on 06/06/2008, -0/+5Okay so call me a noob, but I'm curious, aren't there better liquids to use in this case than water? Steam is dangerous to structures, and conductive...among other things. What makes water the liquid of choice for cooling?
- Arramol, on 06/06/2008, -0/+4Sorry, it wasn't my intention to frost anyone.
- TrevorPace, on 06/06/2008, -0/+4Unfortunately wasn't doesn't have the highest specific heat capacity of all liquids. Ammonia has higher for example at 4.7.
- ElbertF, on 06/06/2008, -0/+4Thanks.
- 471776, on 06/06/2008, -0/+4"Then" and "Than" are not interchangeable.
Seriously, this is just basic English. - charlietuna, on 06/06/2008, -1/+4Adblock seems to keep most sites clear from me.
- brnews, on 06/06/2008, -1/+4How primitive! I want an optical processor instead, electrons are so 20th century...
- TrevorPace, on 06/06/2008, -0/+2Well chip designers had to come up with ways to keep what they want on the chip as well as to create channels that are going around the warmest areas of the chip.
Not to mention that they probably had to make sure each channel is designed so that the water won't cause damage to the chip. - Murdats, on 06/06/2008, -0/+2wouldnt there be a concern about running water weathering away the channels?
of course on this scale I am sure the rules start changing and I have no doubt they have considered it but it would still be an incredibly difficult task. - je12u, on 06/06/2008, -0/+2Seems so logical when you think about it. I think a lot of complex problems are resolved with 'common sense' answers that should work in theory...it's usually the implementation of the idea that gets tricky.
- charlietuna, on 06/06/2008, -1/+3Like most "gee whiz" articles, this praises a new idea while omitting any mention of potential problems in actual production use. Will the water dissolve or corrode internal galleys over the long term? These are small channels that will be rather hot.
- Sairynn, on 06/06/2008, -0/+1Water isn't corrosive.
- FUR10N, on 06/06/2008, -0/+1as long as it's distilled water I don't think that would be a problem
- webcrumb, on 06/06/2008, -0/+1It's cheap, and heats and cools in the normal working range of chips without boiling like an alcohol would.
Water heated by chip->rises up heatpipe->cooled by heatsink/fan->cool water sinks->heated by chip->...
(Convection current) - FUR10N, on 06/06/2008, -1/+2I see what you did there.
- petecampbell, on 06/06/2008, -1/+2I think I'll order a TAB..

It's been a few years since thermodynamics, but as I recall liquid water has a rather high specific heat. I read this article quickly, but I don't think they are relying on the heat of vaporization.
- bobcoxocn, on 06/06/2008, -0/+1That's actually a pretty brilliant idea..
- charlietuna, on 06/06/2008, -0/+1Aqueous solutions can be due to the presence of impurities. Of course I don't think this is turning into an informed discussion, but rather it has all the salient qualities of a pissing contest.
- gahal, on 06/07/2008, -0/+1Icee what you did there.
- Virgule, on 06/07/2008, -0/+1Talking about cooling a computer... Is it best to suck away the heat or push in the cool?
- qwertycopter, on 06/06/2008, -0/+1No pics or it did happen! Wait..
- Dorian822, on 06/06/2008, -0/+1Yeah, I mean water and electricity...what could possibly go wrong?
- groverblue, on 06/06/2008, -0/+1your still gonna have to cool that..
- sanosuke001, on 06/06/2008, -0/+1They mentioned re-using the heat generated by the chips to make electricity. Why can't they do that with current ship designs? Or for that matter, combustion engines? Pump water through it, collect heat, run a turbine, charge a battery.
Seems like a good way to improve efficiency of a system. - kurtwinter, on 06/06/2008, -0/+1What about the inherent problem of overcoming fab pitches due to water's various properties?
- erocklodge, on 06/07/2008, -0/+0You are right about ammonia. It has great uses in refrigeration and heat pipes, but ammonia isn't a liquid at room temperature and pressure, plus it's highly toxic.
- Kitchenfire, on 06/06/2008, -0/+0"The research said that the structure was as complex as “a human brain, wherein millions of nerves and neurons for signal transmissions are intermixed but do not interfere with tens of thousands of blood vessels for cooling and energy supply, all within the same volume.”"
The rise of the machines! - inactive, on 06/07/2008, -1/+1I understand the implications of this research, but what I don't understand is why it's such a big deal. We've had nanotechnology, we've had liquid cooling..
- sanosuke001, on 06/06/2008, -0/+0Water, regardless of what is in it still erodes. Though, on the small scale they'd be using, the relatively slow movement of convection and how smooth the pathways would be, I don't see it as much of a problem. As long as the water is distilled, the pathways would last longer than the chip's expected lifetime I'd assume.
- spitvs, on 06/06/2008, -1/+0Intel does all the neat and cool stuff but cannot even compete in the video card industry what need? The low end Intel chips that they put in notebooks is stupid but they are developing chips that swim in water lol.
- erocklodge, on 06/06/2008, -2/+1Water has the highest specific heat of any liquid. Meaning it can suck more heat out of a chip than other liquids. Plus it also happens to be cheap, plentiful, and non-toxic.
- NRay7882, on 06/06/2008, -2/+1I'll install this on my BTX motherboard. Something about "integrated water" on computer parts doesn't sound right. Kinda like starting the lawnmower while holding tightly onto the blade.
- lusenok2, on 06/06/2008, -2/+1I see many problems with this: dissolution, corrosion, algae growth...
Sounds COOL but impractical. - inactive, on 06/06/2008, -3/+2Since when is liquid cooling new?
- inactive, on 06/06/2008, -3/+1I know what conventional liquid cooling is.. I guess I'm just not that impressed with this "new" technology.
- EggSaladKing, on 06/06/2008, -3/+1It isn't. It is the scale at which IBM is doing it that is new.
- diggit08, on 06/06/2008, -6/+2God damn in text advertising. Damn it to hell. I gave up trying to read that article after having to put up with those ridiculous in text ads. ARGHHHH
/vein pops - diggit08, on 06/06/2008, -6/+2I wouldn't be able to complain than would I?
- inactive, on 06/06/2008, -8/+3That's great!!
