Yup - the arm was in the instructions. I'll add that it has a small lock on it once you push it down.

there was a gray square which I figured was the heat Xfer compound

AMD swears they will void your warranty if you use the "better" stuff (I also would not want too thick a coat) - I may have some lying around, but to be honest I have not messed with building anything since I was a post-doc... and that was so long ago the 'grease' I have is probably like putting wooden cart wheels on a new C-GT.

BTW - another tip: the locking arm on the heat sink/fan unit was difficult to pull over

again, their instructions are vague but it appears they are saying that the CPU is already coated - anyway, it's on to the video card now...
