I have two 360mm rads in a haf stacker 935 case. Currently just cooling my cpu. EK is making full cover blocks for the GHZ 780ti coming out in Feb. I plan to use those on my 780 GHZ sli setup. Do i have enough rad? Or should i add a 240mm rad to loop after the gpu's? And will the Laing D5 pump be enough for all those rads?
