The Vapor Chamber Cooling Design
Implemented cooling solution based on Vapor Chamber Technology, the SPARKLE GeForce GTX 580 Graphics Card runs not only cooler but also much quieter and provides more headroom for users to  explore performance tweaking ! Vapor Chamber Technology is based on the same principles as heatpipe technology. A liquid coolant is vaporized at a hot surface, the resulting vapor is condensed at a cold surface then the liquid is returned to the hot surface. The recirculation process is controlled by a wick system. The coolant is water – but because the chamber is evacuated to a very low pressure, the vaporization process occurs at a much lower temperature than normal boiling point. The complex wick arrangement inside the module controls the flow of water and water vapor so that the system can be used in any orientation. The GeForce GTX 580 GPU heats Vaporization Wicks. Working fluid, pure water, is easily vaporized due to the extreme low pressure (<104 Tor or less). Water vapor moves easily through the vacuum until it meets the condensing  wick - adjacent to the cooled surface - and turns back to a liquid state. The liquid is then absorbed by the Transportation Wick by capillary action and moved back towards the Vaporization Wick. The Vapor Chamber Cooling Design of  the SPARKLE GeForce GTX 580 Graphics Card is much more efficient than a copper heatsink at carrying away the heat because the whole area effectively transfers heat at the same rate.
