What if your future GPU or CPU could throttle itself back when it got too hot, rather than overheating and causing errors or a shutdown? It may be possible, but for now, this is a reality in the server realm. Overheating doesn't happen nearly as often these days when it comes to consumer computing, but once you add in overclocking, serial jobs or multiple linked computers, things can get messy when temperatures rise above a certain level. Particularly with servers, many are designed to shut completely off if temperatures soar beyond a certain point in order to save the machine from irreparable... Read more...
Through a project known as Aquasar, IBM researchers are working on new technologies that could drastically reduce the power consumption and carbon footprint of data centers. Aquasar involves a water-cooled supercomputer that uses 40% less energy than comparable systems that use today's air-conditioned methods.In addition to saving energy, Aquasar takes the waste heat it pulls from servers and uses the heat to help warm nearby offices. By combining these energy savings, a company's carbon footprint can be reduced by as much as 85%. The Aquasar project began one year ago as part of IBM's First-Of-A-Kind... Read more...
Sony has been dealing with the fallout from overheating batteries for a couple of years now, so it should be used to the fire drills associated with running damage control on overheating products. That practice should come in handy, as the latest hot potato form Sony is an entire line of overheating laptops. In cooperation with the U.S. Consumer Product Safety Commission, Sony has issued a voluntary recall of about 73,000 units of its VAIO TZ-series notebooks that were sold in the U.S. between July 2007 and August 2008. The potentially affected models are:VGN-TZ100 seriesVGN-TZ200 seriesVGN-TZ300... Read more...
We're sure you know about the issues with some NVIDIA mobile GPUs, as earlier in July NVIDIA admitted it was taking a $150 - $200 million charge to cover (emphasis ours):... anticipated customer warranty, repair, return, replacement and other consequential costs and expenses arising from a weak die/packaging material set in certain versions of our previous generation MCP and GPU products used in notebook systems. All newly manufactured products and all products currently shipping in volume have a different and more robust material set. Since then both HP and Dell have admitted the issue affects...

Even in the age of green computing and lower power 45nm silicon manufacturing technologies, thermal management, specifically heat mitigation, continues to be a challenge .   Maybe you're a dyed-in-the-wool overclocker or perhaps a silent computing buff that wants things whisper-quiet. Then again, even the average "Joe Sixpack" could probably appreciate how unobtrusive a computer can be and that, as savvy HH readers know, can only be achieved through robust, elegant cooling solutions.  In that vein and out of the Kingdom of Denmark comes Danamics with...

There's no shortage of drama in the Desktop Graphics industry, with bitter rivals NVIDIA and AMD-ATI taking shots at each other at any opportunity.  Though HotHardware Management heritage is of Italian descent and thus not shy of taking on a passionate debate, we generally like to stick to the facts, rather than dabble in rumor hearsay or mudslinging.  There just aren't enough hours in the day to go down the proverbial rat-hole all that often.  However, when the occasion presented itself to dig into the latest allegations of NVIDIA leveraging optimization cheats in their drivers...

You probably recall AOL's 2006 leak of search user data, which actually was more like a flood. AOL published the search logs of 650,000 subscribers, which eventually resulted in some heads rolling, after the smoke cleared. Why not take a tack from Law and Order and rip a story from the headlines, eh? And that's what director Michael Alltop did.The show--which opened Wednesday and runs through June 22--is based on a now infamous real-life search log that included queries ranging from "purple lilac," "happy bunny pictures," and "square dancing steps" to "cut into your trachea," "pee fetish," and...

Why do we buy HotHardware? The answer is always to play games. You don't need to overclock and cool to use Microsoft Word. We want to go places and kill things. But as the worlds we wander through with our weapons have gravitated online, and involve thousands of other players worldwide, cheating at gaming has morphed from a harmless personal vice to a sort of crime. Slate has an interesting look at how this cheating at video games has turned from silly fun into a lucrative business. So, where does gameplay end and cheating begin? Given that virtual property now has real-world value, it's... Read more...
I've seen it before on shows like "Law and Order" - suspects caught because of electronic bridge toll records - you said you were in place X but you were in place Y - and you could in fact have committed that murder.  And so on and so forth.  Well, adulterers beware: E-ZPass is now being used in divorce cases. "E-ZPass is an E-ZPass to go directly to divorce court, because it's an easy way to show you took the off-ramp to adultery," said Jacalyn Barnett, a New York divorce lawyer who has used E-ZPass records a few times.Lynne Gold-Bikin, a Pennsylvania divorce lawyer, said E-ZPass helped...

Aimbot, aimhack, cheats, or what have you is what we’re talking about today. We’ve probably all been victims of cheating at least once during the many hours we have spent playing games in front of the screen. And we all know that cheating usually spoils the fun for everyone. That might be why Intel has embarked on anti-cheat crusade, so to speak, with its research on a new anti-cheating system that would make cheating much more difficult for cheating cheaters. Known as the Fair Online Gaming System, it is unlike contemporary software-based anti-cheating technologies in that it would be built into... Read more...
OCZ's latest solution for cooling their high performance memory modules is the Reaper Heat Pipe Conduit (HPC) system. The Reaper HPC memory uses a combination of an aluminum heatspreader, copper heatpipe, and aluminum fin array to quickly dissipate heat. Heat generated by the memory is absorbed by the heatspreader, where it is then transported to an aluminum fin array which then dissipates the heat into the surrounding air. In theory this method should cool the memory modules much more efficiently than the flat heatspreaders most other memory modules sport.In this article, we evaluate the original... Read more...
For the last several months, DDR2 memory development has been largly stagnent. The fastest DDR2 memory kits from last summer were, for the most part, still the fastest DDR2 memory kits this spring. We haven't seen any truly significant developments in DDR2 since Micron stepped up to the plate with their D9 chips. Although manufacturers continue to release new DDR2 memory, speed increases are fewer and harder to come by. It seems that even the mighty D9 has run out of headroom and it's becoming very difficult to produce faster DDR2 memory while still maintaining acceptible production yields.... Read more...
Now that summer has arrived in the northern hemisphere, there is plenty of it to go around. Computer hardware enthusiasts try to deal with it on a regular basis by incorporating gigantic fans, elaborate water-cooling systems, or even going that extra step toward phase cooling. Heat. It makes computer gamers and baseball pitchers go crazy alike - on days that exceed 32 degrees Celsius, there tends to be a higher frequency of batters being hit by pitchers. Fortunately, Orest Symko, a physicist at the University of Utah, and his team are developing ways to convert heat into sound and then into electricity.... Read more...
Intel plans to "turn up the heat" on AMD: "To decrease the impact of a head-to-head processor pricing war with rival Advanced Micro Devices, Intel must return to the quick development habits it used when producing its Pentium family of chips, Otellini said. Intel backed off that pace after producing the Pentium 4, and soon began to lose market share when AMD launched the Opteron chip in 2003." Intel has certainly been on a roll as of late, and here is the skinny on their future plans according to the article: 2007: Intel will transition the current Core microprocessors to 45nm, and introduce...
