I stand corrected. I didn't see that part. The last time I looked at their instructions was when I was working with my XP3200 (which has an exposed core). I didn't realize they had seperate instructions for processors with an IHS. Maybe I'll reseat my Zalman CNPS9500 tonight since I'll be making a side panel fan hole for my video cards, though I doubt it will make much if any difference, but it's worth a shot.
