Installation takes a little time and patience but isn't extraordinarily hard. With our GeForce 9600 GT video card we began by removing all the screws on the back of the card. That is quite simple to do and afterwards the stock heatsink comes off quite easily. You'll then want to remove the backs of all the memory heatsink so they can affix themselves to the memory modules on the graphics cards. After that, remove the sticky tag on the main GPU heatsink and put the spacers on the holes to screw into. There are both "A" and "B" holes depending on the graphics card you are using. Lining up these four holes with the GPU is a little bit tricky but once you have it lined up you can start screwing in the screws. If all you want is a passive heatsink at this point you are done.
