Colorful is the first manufacturer to develope a completely passive cooler for Nvidia's GeForce GTX 680 graphics card. Called the Colorful iGame GTX 680 Passive Edition, the card uses a completely silent cooling assembly for the 3.5 billion transistor GPU. The card itself is longer than most GTX 680 graphics cards in the market, with a large aluminum fin heat sink spanning its … [Read more...]
Computer Cabinet for Direct Cooling from its Base
MovinCool introduced its new Uptime Racks ECC13 air-conditioned computer cabinet. The cabinet system is manufactured by Computer Room Uptime and cooled by a MovinCool CM12 air conditioner that is built into the cabinet's base. The unit delivers 13,000 Btu/h of cooling capacity directly to the IT equipment housed in the cabinet, resulting in high energy efficiency. The cabinet … [Read more...]
Changes in Surface Texture Double Heat Dissipation
Researchers at MIT have found that relatively simple, microscale roughening of a surface can dramatically enhance its transfer of heat by more than doubling the maximum heat dissipation. To test the process, the researchers made a series of postage-stamp-sized silicon wafers with varying degrees of surface roughness. They found that systematically increasing roughness led to a … [Read more...]
Hot-Water Cooled Supercomputer
The first commercially available computer system that is cooled with hot water rather than air was unveiled at the Leibniz Supercomputer Centre in Munich. The IBM iDataplex system removes heat 4,000 times more efficiently than air-cooled systems using a new form of IBM’s hot-water cooling technology. It cools active components in the system such as processors and memory modules … [Read more...]
Apple's New iPad Has Heat Problems
Heat-related issues may already be plaguing Apple’s new third-generation iPad. According to tests conducted by Consumer Reports, the new third-generation iPad measured approximately 12 to 13 degrees Fahrenheit warmer than the second-generation iPad. Consumers have also reported unauthorized “shut-downs” of their devices in warmer climates but thus far, no official statement … [Read more...]
