Engineers harnessing the same physical property that drives silent household air purifiers have created a miniaturized device that is now ready for testing as a silent, ultra-thin, low-power and low maintenance cooling system for laptop computers and other electronic devices.

The compact, solid-state fan, developed with support from NSF's Small Business Innovation Research program, is the most powerful and energy efficient fan of its size. It produces three times the flow rate of a typical small mechanical fan and is one-fourth the size.

Dan Schlitz and Vishal Singhal of Thorrn Micro Technologies, Inc., of Marietta, Ga. will present their RSD5 solid-state fan at the 24th Annual Semiconductor Thermal Measurement, Modeling and Management Symposium (Semi-Therm) in San Jose, Calif., on March 17, 2008. The device is the culmination of six years of research that began while the researchers were NSF-supported graduate students at Purdue University.

"The RSD5 is one of the most significant advancements in electronics cooling since heat pipes. It could change the cooling paradigm for mobile electronics," said Singhal.

The RSD5 incorporates a series of live wires that generate a micro-scale plasma (an ion-rich gas that has free electrons that conduct electricity). The wires lie within un-charged conducting plates that are contoured into half-cylindrical shape to partially envelop the wires.

Within the intense electric field that results, ions push neutral air molecules from the wire to the plate, generating a wind. The phenomenon is called corona wind.

"The technology is a breakthrough in the design and development of semiconductors as it brings an elegant and cost effective solution to the heating problems that have plagued the industry," said Juan Figueroa, the NSF SBIR program officer who oversaw the research.

With the breakthrough of the contoured surface, the researchers were able to control the micro-scale discharge to produce maximum airflow without risk of sparks or electrical arcing. As a result, the new device yields a breeze as swift as 2.4 meters per second, as compared to airflows of 0.7 to 1.7 meters per second from larger, mechanical fans.

The contoured platform is a part of the device heat sink, a trick that enabled Schlitz and Singhal to both eliminate some of the device's bulk and increase the effectiveness of the airflow.

ASUS announced its new ASUS Xonar DX PCI Express 7.1 Audio Card earlier this year. The company makes the bold statement that the new sound card delivers 35 times cleaner audio compared to onboard audio built into your mainboard.

The new Xonar DX card is tuned for audio quality with 116dB signal-to-noise ratio (SNR) and features other sound enhancing technologies like Dolby Home Theater and DS3D GX. To compare ASUS says that the typical on-board audio solution has 85dB SNR.

The Xonar DX uses the CirrusLogics CS4398 audio DAC that is typically used in Hi-Fi devices. The card is also able to take advantage of the latest DirectSound and EAX 5.0 sound effects in PC games for Windows Vista. ASUS also integrates its VocalFX technology that allows for users voices to be integrated into games via VoiceEX and to emulate background scenes in online chats (ChatEX).

Other features include support for Dolby Digital Live, Dolby Headphone, Dolby Virtual Speaker, and Dolby Pro Logix IIx. The audio processor used for the card is the ASUS AV100 High-Definition Sound Processor. The analog playback sample rate and resolution s 44.1K/48K/96K/192KHz at 16/24 bits. The analog recording sample rate and resolution is the same. A digital S/PDIF Digital Output is featured as well with Dolby Digital and DTS.

The best news for PC users that like the specifications of the Xonar DX is that the card will retail for only $89. The new Xonar DX will fit into the ASUS line alongside the previously announced Xonar sound cards including the Xonar U1 external audio processor, Xonar D2 and the Xonar D2K.

French publisher Ubisoft has announced that it has acquired all intellectual property rights to the name 'Tom Clancy' from the thriller author (Rainbow Six Vegas 2 etc).

These newly acquired rights, which help to guarantee an important multi-franchise product for the publisher, extend on a perpetual basis, free of any future royalty payments, and include use in video games and related products including books, movies and merchandising. The price of the all cash acquisition has not been disclosed explicitly, but Ubisoft implied in its announcement that the initial payment in this fiscal year was of 20 million euros ($30 million). Additional payments are to also be made in the fiscal years of 2008-09 and 2009-10. Hot on the heels of this announcement comes word that they are using that name to build themselves a Tom Clancy MMO.

Recently Tuniq (part of Sunbeamtech) released a trio of power supplies. The Ensemble comes in 1200 and 1000 Watt versions, and their "lower" specced Miniplant is "only" a 950 Watt animal. Despite the fact that the PSU can suck up 950 Watts, this actually is an energy friendly product .. it has everything to do with it's high efficiency topping out at 80%+, no worries though, we'll explain and demonstrate that over the next few pages. According to the specs it's rated at ~87%, which is quite notable and surely important as Energy consumption of our PC's has grown massively over the past year or two. Right, let's head to the next page where we'll discuss some of the features after which we'll dive into a photo shoot, test and verdict.

Some times you'd just wondewr how much money they actually make on graphics cards eh ? At this very moment the Radeon HD 3870 can still can be purchased for little as $189.99, but the 9600 GT has dropped from its $179.99 launch price to just $149.99 in certain scenarios.

In light of those changes, The Inquirer claims AMD is prepping an additional price cut for both of its Radeon HD 3800-series graphics cards. Supposedly, the 3870 will dip to an all-time low of "$159 or less," while the 3850 will sink to $145 or less. Those drops should give the 9600 GT some stiffer competition, especially considering how certain Radeon HD 3850 offerings compare with Nvidia's new budget wonder. Naturally, the price cuts will leave the $200-300 price arena pretty much devoid of any AMD cards once again. Luckily for fans of the red team, recent reports suggest AMD plans to introduce new Radeon HD 4800 series graphics cards some time in the second quarter of this year.

Thse are great prices, I'll sort some stuff out for you deals wise this week.

After extensive partnership efforts between NVIDIA and Corsair, the NVIDIA 790i Ultra SLI platform was found to exhibit extreme overclocking capabilities with the latest in DDR3 memory architectures.  All Corsair SLI-ready partner memory is pre-loaded with EPP2, the latest in memory performance specifications.  EPP2 is designed to deliver an automatic memory performance boost for enthusiasts when used with the 790i Ultra SLI platform.

Back in early February a source familiar with the plans of AMD revealed that AMD Phenom processor models 9550 (2.20GHz), 9650 (2.30GHz) and 9750 (2.40GHz) based on the new stepping will be released commercially in April. Various media reports now suggest that along with the launch of the new microprocessors AMD will also release model 9850 at 2.50GHz clock-speed.

If you search a little then you'll notice that the upcoming Phenom 9750 and 9850 listed at an American e-tail stores.

AMD Phenom 9850 will come as a black overclockable edition works at 2.5G GHz, has the TDP of 125W and it fits in socket AM2+. It should start selling soon and it will cost $302.99. The second fastest in this line up is Phenom 9750 with the same TDP and 2.4GHz clock. It is not a Black Edition and it will sell for $278.99. 

Both CPUs come with free shipping. You can order 9850 here and 9750 here.

The new microprocessors are based on the new B3 core stepping and should generally have a little higher performance due to the lack of the well-known TLB erratum compared to AMD Phenom models 9500 and 9600 available now.

Latest rumors in the channel are now confirming that NVDIA's upcoming GeForce 9800 GTX, normally slated for a release next week. Has been delayed to April the 1st (and that's not a joke).

A well, you'll have to wait a week longer.

We already heard the rumor, which is now confirmed. Intensly sucky howevere is that the trade-up program only applies in Northern America.

BFG Technologies announced today the BFG Trade Up program. The program is designed to give customers a one time opportunity to exchange their current BFG graphics card within 100 days of the original date of purchase for a better model and only pay the difference in price, plus applicable taxes.
