AMD's Radeon R9 290 graphics card already runs fast, but kicking things up a notch is Sapphire, which just launched its R9 290 Vapor-X OC with a custom cooling solution. It has 2,560 Stream Processors, 4GB of GDDR5 memory running at 1,400MHz (5.6GB/s effective), and an overclocked GPU that's been goosed to 1,030MHz, up from a maximum clockspeed of 947MHz on reference cards.
To keep things stable, Sapphire combined its vapor chamber cooler with its Tri-X fans. The vapor chamber is mounted between the GPU itself and the base of the heatsink and cooler assembly to pull the most amount of heat away from the GPU and into the cooler.
Sapphire's Tri-X cooling solution consists of three 90mm fans with dust repelling ball bearings and five heat pipes, including a 10mm core heat pipe flanked by two 8mm pipes and two 6mm pipes snaking through the cooler.
"The stylish fan shroud also contains molded guides to control the airflow across and through the cooler, including over the Power Control circuitry," Sapphire explains. "The combination of Vapor-X and Tri-X technologies results in GPU temperatures between 5 and 10 degrees cooler than with Tri-X alone – delivering industry leading cooling for this generation of graphics cards."
