PowerColor HD 6850 SCS3 1 GB
 

PowerColor's Radeon HD 6850 SCS3 is the first completely passive cooled Radeon HD 6850. This makes it the fastest zero-noise graphics card available today. Instead of the fairly compact heatsink of the reference design, PowerColor is using a massive triple slot cooler which provides the cooling required for the HD 6850 SCS3.
