More efficient heat sinks could sport nanowire whiskers
Sintering is a common process for creating copper heat sinks that involves packing powdered metals into a particular shape and baking it in a vacuum. A funny thing happens though, if you leave out the vacuum part of the equation: you don't get a solid shape, but a porous pile of particles with hollow, nanowire whiskers sticking out of it. The serendipitous discovery could lead to a new way to make heat sinks for everything from CPUs to boilers at power plants. Now researchers at MIT are trying the process with practically every material they can get their hands on. Of particular interest is zirconium, which could be used with fuel rods in nuclear reactors to improve efficiency. The idea of whisker-covered heat sinks may sound strange, but the potential for improving thermal management across a range of applications is huge. Just don't try and pet it -- these things tend to get a little toasty.
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.
SolidLogic GS-L10 Mini-ITX wraps itself in blanket of heat sinks for comfort, fanless existence
Okay, so it's not exactly a looker, but Logic Supply's SolidLogic GS-L10 Mini-ITX is probably meant to be kept out of view anyway, and given its fanless operation, won't give away its whereabouts. Culled from a Serener case and MSI MS-9818 motherboard, the heatsink-laden unit supports three different Intel Montevina processors ranging from the 2.16GHz Celeron M CM585 to the 2.53GHz Core 2 Duo T9400, up to 4GB memory, options for either HDD or SSD storage, and your choice of Windows XP, Vista, or Ubuntu. Connection-wise, we're looking at two ethernet and four USB 2.0 ports, as well as VGA, DVI, and HDMI for video. Prices start at around $861 if you opt out of a pre-packaged HDD, but if you're wanting the full kit and caboodle here, expect to shell out closer $1,900. [Via Windows for Devices]
Corsair's Peltier memory cooler gets demonstrated
Corsair's Dominator memory can apparently get quite hot, particularly if the overclocking bug catches you right. If a product shown off at CES hits the commercial market, however, everything is sure to stay cool. The Peltier cooling device is expected to play nice with second-gen Dominator modules, and when attached to existing heatsinks it can be used to cool a larger heat block in pretty much any water cooling setup. We know, you're probably scratching your head, but hop on past the break for a quick video demonstration.[Thanks, Ryan]
MS responds to new heatsink in 360s
Microsoft has responded (in a manner of speaking) to yesterday's reports that the company has been installing new additional heatsinks when repairing Xbox 360s. Supposedly, these new heatsinks are appearing in refurbished Xbox 360s in the United Kingdom as a means to combat the Red Ring of Death. In response to a query from gamesindustry.biz, a Microsoft spokesperson noted that "regularly updating console components is commonplace within the industry and is a standard aspect of the business for a variety of reasons including cost reduction, improved manufacturability and improved performance." So yeah, they dodged the question. Furthermore, the representative refused to directly confirm or deny the new heatsinks, saying that Microsoft does not provide information regarding hardware updates. Uh huh, and we're sure that Microsoft won't be trumpeting the new 65nm GPUs either. Sure ....Our translation: there are new heatsinks in refurbished Xbox 360s, but admitting that would be tantamount to admitting that the 360 has a systemic flaw, something Microsoft is not keen to do.
OCZ intros "world's fastest" 1200MHz PC2-9600 Flex XLC RAM
Champs don't stay that way long in the computer hardware biz, but one way to ensure that the crown stays in the same camp is to one-up yourself before another firm can beat you to the punch. OCZ seems to be feelin' said mantra, as the company's latest Flex XLC RAM overtakes the previous rendition to claim the "world's fastest" title at 1,200MHz. Of course, we've seen quicker memory stuffed onto graphics cards, but the new motherboard-ready PC2-9600 Flex XLC modules sport a svelte hybrid cooling system that melds passive air and liquid injection systems to give you all the bragging rights you'd ever need. The DDR2-1200 modules are currently available in 2GB (2 x 1,024MB) kits, come with a lifetime warranty, and will run you right around $250.[Via Gearlog]
