NC State researcher finds more efficient way to cool devices, looks to cut costs too
Does your electronic device have you a bit hot under the collar these days? A researcher at NC State has developed a faster and less expensive method for cooling gadgets -- especially those that tend to crank the heat up. Dr. Jag Kasichainula, an Associate Professor of Materials Science and Engineering, authored a paper on the research that implements a "heat spreader' composed of a copper-graphene composite and an indium-graphene interface film to cool devices. Because the two materials exhibit a high thermal conductivity, they allow the device to cool more efficiently while distributing said heat -- 25 percent quicker than the pure copper in many pieces of tech. And if that wasn't enough, the research also details the process for creating the composite using electrochemical deposition. "Copper is expensive, so replacing some of the copper with graphene actually lowers the overall cost.," Kasichainula notes. If you're itching to read a full rundown of the findings, the full text can be accessed via the source link below.
Nest Thermostat update adds 10-day history, helps send chilly air through the home
There's a first for everything, including Engadget stories about software updates for thermostats. If we're going to suddenly start getting granular in our coverage of home automation products, though, we may as well start with the Nest, a device slick enough to make us use "thermostat" and "sexy' in the same sentence. Now that it's been out on the market for about five months, the company's issuing a software update that introduces a couple new features. For starters, particularly fastidious users can now access a detailed 10-day history, showing precisely when and for how long their heating and cooling systems kicked in, as well as the reason for that shift (e.g., you manually changed the temperature, were away). Though you can't view all that data on the device's small, circular screen, you can look it up online or through Nest's iOS and Android apps. Next up is Airwave, a feature that uses your fan to distribute chilled air through the home after your air conditioner has turned off (you know, instead of letting one room get intensely, unnecessarily cold). According to Nest, that feature turns on automatically when the temperature is high and the humidity low, though we're hazy on the algorithm being used there. Rounding out the list, Nest has made certain settings easier to access, and the hardware itself will ship with redesigned connectors that purport to work well even without wall anchors. Save for that last bit, current owners can enjoy all these tweaks via a free software update -- fully automated, 'o course.
Researchers use lasers to supercool semiconductor membranes, blow your mind
Ah, lasers. Those wonderful, super intense beams of light that we've seen used in headlights, projectors, and naturally, death rays. Like us, researchers at the Niels Bohr Institute at the University of Copenhagen figure there's nothing lasers can't do, and have figured out a way to use them to cool a bit of semiconducting material. This bit of black magic works using a membrane made of gallium arsenide and is based upon principles of quantum physics and optomechanics (the interaction between light and mechanical motion).Turns out, when a one millimeter square membrane of gallium arsenide is placed parallel to a mirror in a vacuum chamber and bombarded with a laser beam, an optical resonator is created between them that oscillates the membrane. As the distance between the gallium arsenide and the mirror changes, so do the membrane's oscillations. And, at a certain frequency, the membrane is cooled to minus 269 degrees Celsius -- despite the fact that the membrane itself is being heated by the laser. So, lasers can both heat things up and cool them down simultaneously, and if that confuses you as much as it does us, feel free to dig into the science behind this paradoxical bit of research at the source below. In other news, left is right, up is down, and Eli Manning is a beloved folk hero to all Bostonians.
A closer look at Origin PC's Phase Change cooling system (and its new gaming laptops too)
Believe it or not, we just spent 45 minutes with two of Origin PC's founders and weren't treated to a gaming demo. Then again, the company isn't here at CES to brag about 3DMark11 scores. Instead, it's showing off its new Phase Change cooling technology, which enables the Genesis desktop to be overclocked to 5.7GHz, and which pushes that desktop's starting price from $1,337 to $4,499. So how does that $3,000 feature work? As it turns out, not unlike an air conditioner. The setup relies on a compressor to compress gas, which liquifies first and then evaporates, absorbing heat along the way. The Little Devil chassis used for the purpose of this demo has an LED screen displaying the -40-degree operating temperature, but you won't need it: the system automatically shuts down if it gets too cold, and it won't boot into Windows until Phase Change is up and running. In addition to all this, the Genesis uses liquid cooling around the motherboard, and an air-based system on the video cards. While we were there, we also checked out the EON15-S and EON17-S laptops, which will be available with an updated design sometime this quarter. Though the interior should look familiar to anyone who's ever laid eyes on a Clevo, Origin remodeled the lid, adding a matte finish option and race car-inspired molding (to evoke the idea of speed, natch). As for specs, Origin's founders directed us to the company's website, which suggests the internals won't change along with the design (certainly, the prices remain the same). Expect these to start at $1,539 for the 15-incher and $1,590 for the larger model -- prices that now include 24/7 free lifetime support. Find some photos below and continue on past the break for a video where you can see (and hear) that Phase Change setup in action.
Origin PC boosts Genesis factory clock to 5.7GHz, reveals new EON gaming laptop design
Origin PC has been spitting out 5.2GHz Genesis desktops for a few months already, but apparently some people wanted more. Thanks to a new 'Phase Change' cooling system that'll be available from late Q1, they're about it get it: a Core i7 2700K system factory clocked to 5.7GHz. Cooling controls and temperature displays will help you to establish the proper balance of power and pollution, while lifetime technical support (which now applies to all Origin PCs in the US) is just a phone call away in case you need to share the rush. There's even an X79 mobo inside, offering scope for a Sandy Bridge E upgrade, plus NVIDIA's GeForce GTX 580 in four-way SLI. Origin has a little something for portable gamers too: a refreshed A-panel on the EON17-S and EON15-S laptops to help you strike the right note of grinning malice in front of your LAN victims. It's not yet clear how these updates will affect pricing, but there are plenty of clips on YouTube that'll show you how to smear thermal paste on your credit cards. Full PR after the break.
Zalman reportedly entering the graphics card market, merging GPUs with cooling solutions
Recently leaked slides suggest Korean computer outfit Zalman will soon jump into the ever-expanding graphics card market, initially partnering with AMD on its Radeon series. Known best for its quiet computing technologies, the company's move to infuse GPUs with cooling solutions could enhance the performance of the cards, making overclocking a lesson in simplicity. The slides only show the AMD 6870, 6850, and 6770, but it's feasible more models will appear when official news is released. Given AMD's many board partners, differentiation is important to remain competitive and on their payroll -- graphics cards and their overheating habits is Zalman's cup of tea. Hopefully this brings more innovative products in the coming future (heck, we've already got GPU / NIC hybrids), perhaps as early as CES. Check past the break to view the specifications breakdown for the aforementioned cards.
IBM sees stacked silicon sitting in fluid as the way to power future PCs
Generally, the combination of microchips, electricity and fluids is usually considered an incredibly bad thing. IBM, however, thinks it can combine those three to make super small and super powerful computers in the future. The idea is to stack hundreds of silicon wafers and utilize dual fluidic networks between them to create 3D processors. In such a setup, one network carries in charged fluid to power the chip, while the second carries away the same fluid after it has picked up heat from the active transistors. Of course, 3D chips are already on the way, and liquid cooled components are nothing new, but powering a PC by fluids instead of wires has never been done before. Bruno Michel, who's leading Big Blue's research team, has high hopes for the technology, because future processors will need the extra cooling and reduced power consumption it can provide. Michel says he and his colleagues have demonstrated that it's possible to use a liquid to transfer power via a network of fluidic channels, and they to plan build a working prototype chip by 2014. If successful, your smartphone could eventually contain the power of the Watson supercomputer. Chop, chop, fellas, those futuristic fluidic networks aren't going to build themselves.
Will Intel's Core i7 Sandy Bridge E CPUs ship without fans or heatsinks?
Over the past few months, we've peeked Intel's roadmap more than once, but all told we've been treated to scant few details about its high-end desktop line, Sandy Bridge E (that's "E" for enthusiasts). Today, though, VR-Zone is reporting that the next generation of these CPUs will ship without fans or heatsinks -- a tacit acknowledgment, perhaps, that Intel's home-brewed cooling system will be inadequate in the eyes of hobbyists anyway. We reached out to Intel for comment, and while the company stayed mum on the topic of cooling, it did go out of its way to clarify another point the folks at VR-Zone made in their report. The outlet had said that the forthcoming 3820, 3930K and 3960X CPUs will be rated at 130 watts, but will consume closer to 180W and draw up to 23 amps from the 12V2 supply rail -- all without overclocking, mind you. An Intel rep writes: "TDP expectations for the 2nd Generation Intel Core i7 processor family for socket LGA-2011 are in line with previous generations of high end desktop products." In other words, built-in cooling system or no, the TDP should be in line with what we've seen from other Extreme-branded processors. As for the cooling, it's unclear when, exactly, we'll get the full spill -- the CPUs are rumored to launch before the end of the year, with the quad-core 3820 arriving after the six-core 3930K and 3960X.
NASA's new cooling pump doesn't need moving parts, set to chill out in space next month
It's pretty easy to cool down an overheating desktop computer with an extra fan, but what do you do if there's no air? That's the hurdle NASA's engineers are hoping to clear with a new prototype pump that the agency unveiled last week. The pinkie-sized instrument relies upon a technology known as electrohydrodynamic (EHD)-based thermal control, which uses electric fields to inject coolant through small vents on a thermal cold plate, before moving the extra heat to a radiator and spreading it far away from any temperature-sensitive areas. With no moving parts, the lightweight cooler uses only about half a watt of power and can be sized to work with small electric components or lab-on-a-chip devices. The challenge is to make sure that the pump can survive the vibrations of a rocket launch, though NASA will put it to the test during a rocket mission on June 9 and in 2013, when an EHD thermal cold plate will be placed on the International Space Station. Start your countdown clock and blast past the break for a full press release. [Thanks, Kevin]
Google opening seawater-cooled data center, finally glad it applied for that Wave trademark (video)
Google raised a few eyebrows when it purchased a Finnish paper mill back in 2009 -- what, the world, wondered, would the king of cloud services want with reams of tree guts? Space for a data center, of course -- and a seawater-cooled one at that. Google's Joe Kava told GigaOm that, when it launches in the fall, the center's temperature will be regulated by a quarter-mile of seawater tunnels inherited from the building's past tenants. One of the hardest parts of getting the system up and running has apparently been figuring out a way to clean corrosion from salt water without taking the system offline. Google's also working to limit the center's impact on the surrounding ecosystem, making sure that the water itself is cooled down before being pumped back out. Between this and those wind-powered data centers, it looks like Captain Planet's always got a cushy IT gig at Google to fall back on, should he ever fall on hard times.
ORNL energy harvester turns heat waste into electricity, converts hot machines into cool customers
We've heard of turning yesterday's lunch into tomorrow's electricity, but a new energy converter coming out of Oak Ridge National Laboratory harnesses the power of a different type of hot waste. The as-of-yet unnamed thermal waste-heat converter has the potential to cool electronic devices, solar cells, and computers while generating electricity from excess heat. Its creators see the new conversion process being used to reduce the massive amounts of heat generated by petaflop computers. The converter employs up to one thousand tiny cantilevers attached to a one square inch surface (e.g. a computer chip) to produce between one and ten milliwatts of electricity -- admittedly a very small amount of energy. However, it's creators are quick to point out that a slew of these converters could generate enough power to perform small tasks in the heat-generating device -- things like sensing when a server room gets too hot for comfort. Sure it's a small step, but if they can get this stuff to save our future babies from cooking, we're all in. Full PR after the break.
ASUS Sabertooth P67 motherboard sheds its skin, feels better without it
There's no denying the ASUS Sabertooth P67 motherboard looks fantastic, and The Tech Report didn't spare praise for its military-grade components or five-year warranty in a recent review, but the publication also reports that the standout feature -- that component-cooling "Tactical Jacket" -- may hurt more than it helps. The plastic shroud has been re-dubbed "Thermal Armor" since our last run-in, but that doesn't change the result: ASUS doesn't ship the primo slab with a dedicated cooling fan, so component temperatures can actually go up ten degrees Celsius when wearing the shroud with a system under heavy load. Of course, cooling depends on a number of factors, but we were hoping the Sabertooth's unique coat would be a positive one. Back to the drawing board.
Researchers find graphene transistors cool themselves, silicon counterparts seethe with envy
We've seen graphene promise some pretty slick tricks already: budget-minded bendable batteries, superior stain resistance, and upping ultracapacitors' energy density. We can now add self-cooling transistors to the list of awesome, yet unfulfilled possibilities for these microscopic sheets of carbon. Using an atomic force microscope, a team of researchers at the University of Illinois led by Professor William King discovered that graphene transistors have a thermoelectric cooling effect where they make their metal connections. This self-cooling is greater than the resistive heating that normally follows the flow of electrons -- meaning graphene-based electronics from the future could make their silicon competition look decidedly uncool in comparison.
GE's new phase-change based thermal conductor could mean cooler laptops -- literally
It's no secret: if your laptop sits atop your lap for an extended period of time, you're going to get burned -- okay, so maybe not burned, but you're definitely going to feel the heat. Luckily GE has been working (under contract for DARPA) on a new phase-change based thermal conductor that promises to cool electronics twice as well as copper, at one-fourth the weight. The breakthrough means big things for those of us who'd like to make babies one day, but we doubt that's why DARPA's shelling out the big bucks -- the new material functions at 10 times normal gravity, making it a shoo-in for on-board computing systems in jetliners. Using "unique surface engineered coatings" that simultaneously attract and repel water, the new nanotechnology could mean not only lighter, cooler electronics, but also an increase in computing speeds. Goodbye scrotal hyperthermia, hello cool computing! Full PR after the break.
Federal Excess: FedEx introduces liquid nitrogen-cooled biotech shipping, we can envision other uses
Just think about this the next time a FedEx van comes speeding past you -- that four-wheeled transporter could be carrying containers equipped with liquid nitrogen cooling that keeps its innards at a chilly -150 degrees Celsius. Don't worry, though, says FedEx, the use of dry vapor is actually safer than the currently used dry ice and classifies this new methodology as non-hazardous. While we may like to poke fun, it sounds like a pretty legitimate boon for healthcare and biotechnology shipments, which can now be maintained at a deeply frozen temperature for up to 10 days at a time. FedEx will provide the self-sufficient container and collect it upon delivery of the goods, while also monitoring its condition during transit. No word on whether or when DiGiorno will be signing up for the service. [Thanks, Pavel]
iFan concept uses gusts to power your iPhone, solve lingering reception issues
Still haven't found that case you've been looking for? At last, the promise land. Designer Tjeerd Veenhoven has crafted a partly nifty, partly hilarious new wind-powered iPhone charger / case, appropriately dubbed iFan. In theory, at least, this here case would wrap your iPhone up for protection and then catch wind gusts from wherever, in turn rejuvenating your phone as you talked and walked. There's even a bicycle attachment mockup for those who'd rather place it on their handlebars and kick things up a notch. Unfortunately, there's no word on whether the process can be reversed (i.e. if the blades can be turned into a battery-powered cooling machine when you're at full capacity), nor a hard on-sale date. But hey, at least there's no jailbreak requirement. [Thanks, Man Yong Toh]
NZXT's Sentry LXE touchscreen fan controller turns you into Storm, minus the cheese
We know, you're probably scoffing at those mortals still using "fans" to "cool their gaming rigs," but unless you've thrown down the cheddar on a swank liquid cooling solution, you'll probably find yourself at least mildly interested here. NZXT has taken a break from the mice and keyboard routine to break out a rather unique piece of kit in the Sentry LXE. This touchscreen fan controller connects to one's desktop via PCIe, and from there provides finger control of up to five internal fans. Users can adjust each one individually, set it to automatically keep the machine at a given temperature or create a silence that would spook even the Reaper. As you'd expect, there's an inbuilt temperature alarm to notify you if temps head north of a designated point, and all this fun awaits you in exchange for a low, low $59.99. Head on past the break if you're in need of a video demonstration.
Ask Engadget HD: How do I keep a closet full of home theater equipment from overheating?
Last week we asked how to achieve your wildest home theater desires and this week we have a followup in that same theme. Moving all those home theater components out of the way helps achieve the clean look so many desire, but Edward wants to know how do you do it? "I've seen different instances where people have moved the majority of their home entertainment components away from entertainment centers/tables and put them in closets. I'm interested in doing this with my system, essentially putting everything out of view except for the TV and speakers. I'm lucky in this instance because I have a closet on the opposite side of the wall where the TV is mounted and its an empty coat closet about 30 x 30. What I'm looking for are tips regarding IR blasters and shelving/cooling issues for the components in the closet. I'm looking to put a HK AVR-254 receiver, U-Verse STB (not DVR), Wii, Xbox 360, BDP-3600, and a small Ethernet switch in the closet. I live in Dallas Texas so summers are a concern and I want to know what people have been doing in regards to cooling since closets aren't well ventilated." We're sure you all have suggestions on how to keep the air and control commands flowing even in tight spaces. We put together our own how-to move your boxes away from the HDTV, but we don't have a lot of HVAC advice, so pitch in.

Core i7-equipped MacBook Pro CPU hits 100 degrees Celsius (updated)
Hydrocarbon fuel cell? 600 degrees Celsius. Large Hadron Collider? -271 degrees. Microwave drill? 2,000. Your run of the mill Core i7 MacBook Pro can't compete with these extreme temperatures, but that doesn't mean it can't get pretty darn warm under pressure. PC Authority recently put the latest edition of Apple's sleek silver classic through a series of torture tests, and found that running Cinebench could cause the CPU temperature to climb over 100 degrees Celsius. The metal shell proved ineffective at dissipating the heat as well as the similarly equipped Fujitsu Lifebook SH760, which finished the same test at 81 degrees, and actually required PC Authority to run the MacBook Pro on its side (see pic above) to complete certain tests. The site thinks that Apple's cooling solution may be inadequate for a Core i7, but these results could be a fluke -- in our experience with the machine, we actually noticed an improvement over the egg-cooking solutions of yesteryear. Update: We'd like to point out that the temperatures described were related to the CPU internally, and not the actual case of the laptop.
Researchers teach liquid to flow uphill, hope to cool future CPUs (video)
Another day, another experimental CPU cooling method that may or may not come to pass. We've seen "thermal paste" from IBM and polyethylene from MIT, and now researchers at the University of Rochester have developed a method for coaxing water along nanometer-scale grooves carved into silicon. So hydrophilic are the patterns that water will even flow against gravity (and we've got the video to prove it). Not only are the structures so precise and nondestructive that the surface feels smooth to the touch, but they also trap photons, according to The New York Times, "so the grooved silicon appears pitch-black." And who knows? Maybe your next PC will be cooled by streams of water flowing freely inside the case. It's a nice image, anyways. Peep the video after the break to see it in action for yourself.
