Have I just been thinking that I could not manage to build the fan itself on the graphics card. But the concerns I have made completely in vain. Easier than ever. Depending on the system there are only a few screws need to be set. You also need not afraid of applying the coolant to have easy and evenly already passts. Depending on which mode you take 12V or 5V differ the volume of the fan. Because I wanted to have a particularly quiet PC, I connected the 5V connector. Almost inaudible! :-) Definitely recommended, especially price = money, could not be better!
