Liquid Metal CPU Cooling

Liquid-Metal Cooling Loop Technology for CPU and processor cooling,
for laptops, desktops, servers, and graphics cards
The ever increasing demands put on cooling solutions for semiconductor devices have never been greater than today and there are no indications that these requirements will diminish in the future. With higher power dissipation due to higher speed processors, ever increasing leakage losses and extremely high heat flux densities due to hot spots on the chip, the demand for advanced cooling solutions continues to increase.
Until recently the demand for advanced cooling solutions was reserved for a small fraction of the ICs produced. Today these needs are becoming pervasive. New CPUs in almost every application are starting to require more than just a heat sink and a fan, and the need is not just with the CPU. In a modern portable computer or server there are several different heat sources that require advanced cooling. One can easily imagine a CPU, GPU, power supply, and other heat sources that need to be cooled.
nanoCoolers has developed a unique approach to cooling these high power heat sources. Cooling with liquid metals has been used for decades in the nuclear reactor industry, but never before have the systems been miniaturized and developed specifically for computer cooling. nanoCoolers has developed solutions to address the high heat source issues for portable computers, desktop computers, servers and other electronic applications. Within each of these categories are specialized situations that have additional needs, such as the elevated temperature requirements for ruggedized computers, or the overclocking requirements from gamers. nanoCoolers' advanced liquid metal cooling solutions address each of these concerns.
Processor Cooling and CPU Cooling for Portable Computing
Each application has issues with high heat flux densities and high power dissipation, but each also has their own unique issues that need to be addressed. nanoCoolers' solution for portable computers not only solves the power dissipation and high heat flux densities with the use of a highly thermally conductive liquid metal but also allows the system to be completely orientation independent. Since our solution is a completely filled and sealed unit, there are no gravitational effects on the thermal solution and therefore on the computer itself. Our electromagnetic pump, consisting of magnets and electrodes allows for extremely small pumps with a variety of profiles. Since the pump has no moving parts, it is inherently reliable. In the future, advanced cooling solutions will be required in portable computers for cooling CPUs, GPUs, other ICs, power supplies and even fuel cells. Our technology lets the system designer determine how many heat sources they would like to cool and at what remote location they would like to dissipate the heat. Another trend for portable computers is to make the computer thinner. nanoCoolers' heat exchangers can be made extremely thin to allow for these design challenges. The heat can be efficiently removed from the heat source and then transported to a remote location where it can be rejected to ambient air. Finally, one of the most important issues with a portable computer is the battery life of the unit. nanoCoolers' thermal solution is not only very power efficient, it could also be designed to vary based on the amount of cooling needed. If the system is idling, the current to the pump could be reduced or even shut off. However, if the CPU is running at 100%, the pump current could be increased for maximum cooling. These attributes allow for system designers to be able to design the very best portable solution available.
CPU Cooling and Graphics Card Cooling for Desktop Computing
Desktop computers have many of the same issues as all CPU driven devices; high power dissipation and high heat densities. Our desktop solution solves the most demanding thermal requirements. Desktop solutions might not be as concerned about power efficiencies,
I don't expect the slashdot editors to live in poverty but I think having three slashvertissments one after the other is really pushing it. This one even goes directly to a sales pitch with a sales contact at the bottom...
Mother is the best bet and don't let Satan draw you too fast.
Ads for nerds, stuff that pays.
Schrodinger's cat is either dead or really pissed off...
...what happens when our heatsink tries to kill John Connor?
I actually went ahead and read TFA, at least the linked one.
Although there was talk of "high tech this" and "required for the future" type crap, there really wasn't a whole lot of meat to the story.
Maybe I missed the link that actually describes what kind of metals they're using, how the pump actually works (it's magnets! doesn't count) and what types of temperatures they're able to achieve relative to other liquid cooling methods.
Could someone please fill in the other half of this submission, this time with less Sales pitch and more Info?
Try synthetic turf. It's a proven technology, used for years because its rugged construction is so hard to distinguish from real grass roots.
Bored with water cooling?
Bite your tongue! How in the world could anyone ever get bored with cooling CPUs with water? I've thrown dozens of water-cooled-CPU-themed parties in the last several years and my guests have never wanted for excitement!
Once there was this time at one of the parties that this one CPU got up to 68 degrees celcius. Way too hot! We put a custom water cooler job on that guy and got it down to 45 degrees celcius in no time. Good times.
How could you ever be bored!?
I'm a big tall mofo.
"-1 Troll" is the apparently the same as "-1 I disagree with you."
Put all your Terminator 2 jokes here, please.
Can't think of any at the moment... but I'll be back!
There is nothing more practical than a good abstract theory.
> it is probably a gallium alloy
r mo4.html . They even claim it is nontoxic (no cadmium or mercury).
:-) Cooling wise, I mean.
Or some other weird alloy. You can buy "liquid metal" for fun at http://www.scitoys.com/scitoys/scitoys/thermo/the
But I still wonder what this has that water does not?
Not quite as extreme as you think. According to Pat Gelsinger (Intel VP), the surface area power dissipation of a modern CPU *is* rapidly approaching that of a nuclear reactor (around 150-300W/cm2)
Of course even when that becomes the case it doesn't justify the use of sodium or lead to cool them. Si starts to break down at 120 degrees C and the primary concern for CPU makers is to maintain temperatures well below this. Sealed water cooling systems will become widespread within the next couple of years but for now liquid metal is just a gimmick for the overclocking crowd.
For all intensive porpoises your a bunch of rediculous loosers
While common or "garden" mercury is quite familiar to element watchers, a far more rewarding sight is the rare "mercury of paradise." Element watchers are dying in droves to see this incredible manifestation of mercury.
For the record... Water is chemically the best cooling agent available. The reason that liquid metal is used in nuclear reactors is that it's much easier to contain in a closed environment than water because it has a MUCH higher boiling point. For those of you that are concerned about the electroconductivity of your coolant, I suggest mineral oil. Mineral oil is cheap, cools well and above all not electroconductive. Unless, of course, your CPU is generating heats at nuclear levels, then i guess liquid sodium might be the only route.
Best of luck trying to get rid of the heat. Remember, convection won't work, only radiation.
/. readers here. Oh well, you know what they say, "it's not what you know, it's who you know".
Silly, convection couldn't work because there is no real "up" in space. You know? Heat rises? I therefore propose the use of fans. Imagine how fast the fans could spin in the vacume of space!!! They would be much more effective "up there" than down here with all this inefficient "atmosphere" crap. The fans could also redundantly double for propulsion when needed.
Why has NASA not thought of these things? NASA really ought to be hiring real geniuses like many of the other gifted
War crimes, torture, lies, illegal spying... Would someone give Bush a blowjob, already, so he can be impeached?
Don't judge it by that Terminator film.
