Hi, I've got this eVGA 7950gt that at stock speeds runs at upto 83c under load.. ie Bioshock. Because I need best performance for the newer games, I need to run det 163.71. It will do 650 core without probs, 680 will eventually give me artifacts.. so too hot. Does anyone know if the zalman vf900 or the zalman fatality fc-zv9 coolers will fit a 7950? Also any voltmod links for this card would be greatly appreciated.
