Arctic Silencer Rev.4 will not fit on X800XL?

I have read reviews that said that it had fit, maybe I need a mod or something. The thing is that there are two extra screws on top, where there are no holes in the video card and connects to itself on the other side of the card. Should I just cut these off and sand it down, and it will be fine, or what should I do?

You got the wrong one man. You need the Rev. 5 for the X850 series.

actually the one he needs is the ATI Silencer 5 rev2. Just like the one I have.....
