Vapor-X Cooling

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.


Black Diamond Choke

Choke is an important component of the graphics card. By working with the component engineer, Sapphire’s patent pending choke is 10% cooler and offers 25% more power efficiency than a normal choke. The graphics card will be more reliable and save energy.

Full Solid Cap Design

Improved reliability and better overclocking are possible by using only high-polymer, aluminum capacitors which posses far superior characteristics than regular aluminum capacitor for a longer product life. When operational temperatures drop by 20 °C, the product life span is extended by a factor of ten, when the operational temperature increases by 20 °C, the product life span only decreases by 10%.
