rudrax Posted July 7, 2012 Share Posted July 7, 2012 More Screenshots: Many of our readers have already seen Gigabyte’s WindForce 5X cooling system mounted on Nvidia’s GeForce GTX 680 GPUs. So now we’re quite surprised to see that an AMD “Tahiti 2” based design is almost ready for prime time although we’re still waiting for the GTX 680 WindForce 5X. The likely naming scheme is Gigabyte Radeon HD 7970 SuperClock WindowsForce 5X and the cooling system reportedly includes a massive vapor chamber solution that’s cooled by five 40 millimeters fans. Gigabyte’s Windforce 5x is practically cooled by five 40 mm diameter fans that will probably generate some serious noise. However, they will, most likely, offer more efficient cooling than fans that blow air in all directions. Gigabyte used a huge, three-slot wide cooling system that has a vapor chamber at the bottom that’s taking the heat of the GPU and the on board memory. The heatsink attached to the vapor chambers is likely improved by five 8 mm huge heatpipes that are increasing the heat transfer from the vapor chamber top the rest of the heatsink. The densely packed heatsink fins are topped with a metal plate, creating vertical tunnels through which the 40 mm top situated cooling fans will pull fresh air coming from the bottom of the card. The fact that the air is travelling through the small space between the heatsink fins for a smaller distance is actually a significant improvement. If a back blowing turbine-like fan tried to push air through the entire length of the video card instead of its height as fins are oriented now, the rotational speed would have had to be much higher, and the cooling efficiency would have been considerably lower. The thing is that pushing air through such long “tunnels” between the tightly packed fins leads to increase air friction between the air and the “tunnel” walls, and the rotation speed of the fan must be greatly increased to manage to push the air through the entire length of the “tunnel”.
