Product information: NexXxoS nVidia 6800/7800 Graphics Card CoolerThis is a complete graphics card cooler designed for nVidia G70 7800GT and 7800GTX cards, as well as all nVidia GeForce 6800, 6800LE, 6800GT and 6800Ultra that follow a reference Design (AGP and PCI-E), based on the Alphacool NexXxoS cooler series. The copper cooler has parallel-running channels in the PCF design meaning the surface for the heat dissipation is drastically increased. The water concentration takes place centrally, in order to ensure best possible cooling. This makes possible stable function at extreme summer temperatures, highest overclocking potential and low noise in one blow. This block is conceived for highest requirements, therefore the RAM chips are also cooled . The channel process leads directly across the RAM components, in order to ensure optimal cooling. The cooler base is absolutely flat, in order to adjust the differences in height, is enclosed for the RAM of components, 8x 1mm thermalpads. The radiators have the GPU only over 1mm remainder floor thickness, in order to achieve optimal cooling values. The sealing between plexiglass and copper cooler box is made by a long-life O-ring. The attachment is made by the drillings for the standard air coolers with screws, existing on the nVidia cards. Two 5mm drilling for optional LED lighting is present. The G1/4" connections are designed for all watercooling systems. Optimally for all SLI systems by its small depth!
