Nvidia has taken its fair share of heat over, well, the heat output of its high-end Fermi cards, namely the GeForce GTX 480. According to news and rumor site Fudzilla, you can expect the upcoming GTX 580 to run a little bit cooler and quieter.
This won't be the result of any major architectural changes, as the GPU will still run hot with a TDP approaching 250W. Instead, Nvidia chose to tweak its cooler design so that it runs more efficiently, essentially sweeping the heat output under the carpet, if you will.
We'll find out soon enough how effective the new design is. Fudzilla says the GTX 580 will launch in the morning hours of November 9, exactly one week from today.
Power supplies aren't the only thing going modular these days, so are computer cases. And leave it to Antec to go all-in with its new LanBoy Air, which looks a little bit like a Transformer, and acts like one too.
"Antec's Skeleton was universally lauded as the most innovative chassis ever. The LanBoy Air builds on the Skeleton's open-air frame design, combining it with a familiar form factor and fully modular construction," said Scott Richards, senior vice president at Antec. "This chassis offers our most avid users the platform they need to push the limits of what they imagined possible in high-performance system design."
The LanBoy Air comes covered in mesh, giving users all the benefits of a truly open-air setup (like HTPC's TechStation or Danger Den's Torture Rack) with a bit more protection. Cooling is the name of the game here, with spots to mount up to 15 fans.
Other features include 11 total drive bays, CPU cut-out, support for graphics cards exceeding 15 inches, three USB ports (including a single USB 3.0 port), and a bunch of parts to move around and customize (check out the video).
Some pretty smart folk from Sweden's Institute of Technology recently discovered that if you add nanoparticles to water, you can significantly improve its ability to conduct heat to the tune of 60 percent. This discovery could be a boon to server farms, which are notorious power hogs because of the level of power needed to keep everything chilly, or at least from burning up.
"What we are using are nanofluids, which are fluids engineered to contain nanoparticles dispersed in such a way that the liquid's capability to move heat is much enhanced compared to normal cooling fluids," said Mamoun Muhammed, Sweden's Institute of Technology.
"For example, if you are using water to cool electronic equipment and you add these nanoparticles, and create a nanofluid, it improves the water's capability to conduct heat by 30 to 40 percent."
The benefits here are threefold, says Muhammed. First, companies will save a bundle on the cost of cooling. Second, their electronics will perform better as a result of the lower temps. And finally, nanofluids represent a greener technology than current cooling methods.
"I think within 3 to 7 years we could expect to see a breakthrough and a mainstream application of this nanofluid technology," Muhammed added.
The problem with most passively cooled videocards is they typically bring weaksauce gaming performance into your home theater, as if all you'll ever want to do on your swank 52-inch LCD is watch movies and play the occasional round of Peggle. That's why we're stoked to see Gigabyte release a totally silent Radeon HD 5770, so far the only 5770 on the planet to ship without a fan.
Keep in mind we don't have one of these in for testing, but we have spent time with AMD's 5770 model and liked what we saw. Gigabyte's latest version -- GV-R577SL-1GD -- trades in the stock cooler for a passively cooled heatsink with four heat pipes running through a whole bunch of aluminum fins. Underneath it all sits an "ultra-huge" copper base plate.
Gigabyte seems to think it's all pretty effective, claiming a decrease in temps of 5-10 percent over traditional designs. We're skeptical those figures will hold up in the real-world compared to actively-cooled cards, but hey, as long as the card doesn't fry itself or burst into flames and take our home theater down, we could care less where it ranks.
No word on when this one's shipping or for how much.
Modern day laptops are loaded with powerful, heat producing components that can often lead to overheating, especially if you’re asking your laptop to do some heavy lifting. If your laptop ever feels particularly hot in certain spots, or sometimes randomly shuts off, there's a good chance that overheating is to blame.
And if your laptop is no longer covered under warranty, fear not. We’ve put together a step-by-step guide for both computer novices and hardware enthusiasts that’ll show you exactly how to deal with overheating problems on your own.
Kingston has zeroed in on water cooling enthusiasts with its latest memory line, the HyperX 'H2O' series. Available in dual- and triple-channel packages, these kits run up to 2133MHz and include water cooling barbs integrated onto the heatsinks.
"Water cooling is desirable for its quiet operation and long-term reliability. We are bringing HyperX H2O to market as a solution for PC enthusiasts who want to build water-cooled systems using high quality Kingston products," said Mark Tekunoff, senior technology manager, Kingston®. "HyperX H2O is a natural extension of Kingston’s offerings for performance users. Our goal is for users of all levels and interests to have a Kingston product that meets their needs."
Kicking off the line are three kits, including:
4GB DDR3-2000 (CL9-11-9-27 @ 1.65V), two sticks
4GB DDR3 2133 (CL9-11-9-27 @ 1.65V), two sticks
6GB DDR3 2000 (CL9-10-9-27 @ 1.65V), three sticks
All three kits are available now, with pricing set at $157 (4GB DDR3-2000), $205 (4GB DDR3-2133), and $235 (6GB DDR3-2000).
Oil immersion cooling isn't anything new, and long-time Maximum PC readers will recall our experience with Hardcore PC's oil-cooled Reactor back in December, 2008. Puget Systems, one of the few remaining boutique PC vendors to avoid being bought out by a bulk OEM, also sells a DIY oil-cooled kit, and it's just been updated.
The new Aquarium PC Version 3 is larger than any previous version and can now accommodate full E-ATX motherboards. But that isn't the only change.
"The biggest improvement is that it allows the power supply to be mounted on the motherboard tray, making it much easier to maintain the PC, as you don't have to worry about the power supply sitting on the bottom of the tank as you pull the motherboard tray out of the aquarium," Puget explains. "It also has more than twice the cooler power!"
To prove it, Puget dunked "the most extreme hardware available" into the revamped Aquarium, which consisted of an Intel S5520SC workstation board, two Intel Xeon X5677 processors clocked at 3.46GHz, 12GB of Kingston DDR3-1600 memory, a 30GB Kingston SSDNow V Series SSD, two ATI Radeon HD 5870 videocards, and a Corsair HX1000W PSU. You can catch the YouTube video right here.
The Aquarium and Cooling Module V3 is available now for around $670 and includes all the parts you need to send your PC swimming in mineral oil.
PowerColor today announced its LCS HD 5870 V2, an upgraded version of the original LCS HD 5870 that now "features unprecedented factory overclocked settings."
Calling it "unprecedented" might be stretching things a tad, but not by much. With the GPU factory overclocked to 950MHz, the LCS HD 5870 V2 matches Gigabyte's GV-R587SO Edition card, the only other HD 5870 GPU we spotted on Newegg clocked higher than 900MHz. More surprising, however, is PowerColor's decision not to goose the memory, which comes clocked at 4,800MHz, or 200MHz slower than the original LCS.
Like the previous version, only water cooling gurus need apply. The LCS HD 5870 V2 comes equipped with high-flow 3/8-inch and 1/2-inch fittings with captured o-rings to help prevent leakage.
"We got very positive feedback from the first version of the LCS HD 5870," said Ted Chen, CEO of TUL Corporation. "Now we released an upgraded version with factory overclocked settings and offer a cool working environment. We're sure that it will exceed expectations from gamers."
As with most of PowerColor's HD 5870 line, this newest release will come bundled with a Dirt 2 coupon, though the company didn't say when this will hit retail or for how much.
Boutique system builder iBuyPower is bringing its portable LAN Warrior back into battle, this time equipping the mATX rig with a liquid cooling setup.
"LAN party gamers push their systems to the limits, making liquid cooling a necessity," said Darren Su, Vice President of iBuyPower. "The liquid cooled LAN Warrior II provides gamers with a way to keep their system safely overclocked without forcing them to haul around a full sized rig or sacrifice power."
Pricing starts at $750 for an AMD-based setup, $800 for an Intel P55 configuration, and $1,000 if stepping up to Intel's X58 platform. If you have the jingle, you can stuff up to two videocards into each one, including a pair of ATI HD 5970 graphics cards for quad-CrossFireX fun.
The problem with all-in-one (AIO) PCs is that the crammed confines don't offer the same cooling potential as a typical desktop, and so lower end components end up being used. Well, get ready to change the way you look at AIOs.
Asetek, which provides self-contained liquid cooling solutions to OEMs, has come up with a prototype all-in-one that's completely water cooled. Measuring no thicker than an iMac at 58mm, the prototype setup
consists of an Intel Core i7 920 processor and GeForce GTX 280M. The two combined consume over 200W.
As showcased in a YouTube video, Asetek hides a high-performance radiator, low noise fans, and a proprietary low-profile pump all within the vertical stand. A couple cold plates attach to the CPU and GPU, keeping the whole thing cool and potentially opening the door to high-end gaming in an AIO form factor.
