Well the fan will only go in one way but yep it did power up and speed up in 3d apps (before it crashed) In 2d mode the screen just went black and seemed to shut down, same happend in 3d only much quicker.
GPU surface looks quite flat to me, AC3 spread very well. I tried a thin and thick layer and nothing changed really. AC3 seems to be a problem for FX cards. Im not touching my 5950 when it arrives thats for sure, sorta tempted to play with the 5900 now though. Custom heatsink etc.
