AMD TFE 2008: Heatpipes and Vapor Chambers

The Inquirer is at AMD's TFE 2008. Today they are talking heatpipes and vapor chamber technology they are seeing there.

The water boils, moves down the tube, hits a cool spot, and then condenses. The heat is transferred by the vapor from the hot spot, usually a CPU or a GPU, to the cool spot, the fins or heatsink. Simple so far, but how does the water get back from the cool spot where it condenses to the hot spot where it is needed? If you are thinking gravity, you are only partially right, it can work via gravity, but that is a minor portion of the flow. Also, if you rely on gravity, make sure the geek installing your heatpipe doesn't angle the computer wrong or things get very ugly.

New Vapor-Chamber Cooling Solution For Radeons

Tom's Hardware discusses a vapor cooling chamber that has been married to AMD's Radeon.

Utilizing the Multiwick and Boiling-enhanced technologies (belonging to its own holding company, Convergence Technologies Limited), the GVC-1 was co-developed with Dr. Gamal Refai-Ahmed, an AMD fellow and Chief Thermal Architect http://en.wikipedia.org/wiki/Architect . The new GVC-1 is nearly half the footprint of the stock-cooler for the ATI ati Radeon HD4870. During testing, the GVC-1 outperformed the stock cooler by nearly 15 percent, translating into advantages for overclocking and acoustic noise.
