The PowerColor SCS3 heatsink has been updated to handle the 130W TDP Pitcairn Pro GPU. Instead of direct cooling, the PowerColor HD7850 1GB SCS3 makes use of the chassis` ambient cooling to keep thermal levels within optimal levels. The new SCS3 cooling solution consists of six 6mm heatpipes arranged in a g-shaped design distributing heat from the HD 7850 core to several sets of aluminum fin arrays. Understandably, the PowerColor SCS3 carries the stock core clock of a typical HD 7850 set to 860MHz so thermal load is more manageable. The PowerColor AX7850 1GBD5-S3DH requires a single 6-pin power connector and has a full-size DisplayPort and HDMI which supports 4K displays as well as a standard DVI port that supports resolutions up to 2560x1600."
