SAPPHIRE Technology was the first company to implement cooling for PC graphics cards based on Vapor Chamber Technology. Vapor Chamber Technology was previously used in blade servers to provide more efficient yet compact cooling. SAPPHIRE’s Vapor-X cooler was introduced in 2007 with its HD 3870 ATOMIC Edition graphics card and then rolled out to the global market with the successful TOXIC HD 3870 and HD 4870 series. Based on the successful experience on TOXIC with Vapor Chamber cooler, SAPPHIRE introduces the new Vapor-X graphics card series to bring an users a silent and efficient cooling solution based on Vapor Chamber technology. With such a efficient cooling system, the Vapor-X series has a more potential in overclocking and longer life expentancy.

Vapor Chamber Technology is based on the same principles as heatpipe technology. A liquid coolant is vaporised 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 patented wick system. SAPPHIRE Vapor-X flattens the whole system into a slim chamber - which in the graphics application is mounted in contact with the surface of the graphics chip.
