I didn't see the pics but if the instructions didn't mention it, if the heatsink requires you to remove the stock cpu fan bracket, an insulated backing plate will be included that goes on the underside of the motherboard. the mounting screws will attach to it. Make sure the insulated side is the one that touches the motherboard.
And then as I posted, up came the pics. Nice looking cooler. From what I can see this will require you to remove the stock cpu bracket. Most motherboards have an insulated bracket and from what I can see it looks like all you'll have to do is remove the stock bracket and replace it with what you have in your hand.
