Look again. Observe the last three paragraphs of the section on p4/amd64 processors.
"Since the vast majority of the heat from the core travels directly through the heat spreader, it is more important to have a good interface directly above the actual CPU core than it is to have the heat spreader covered with compound from corner to corner.
The photo to the right shows how the pressure from the heatsink base spreads the compound and also shows a P4 with the heat spreader removed to show the location of the actual CPU core that is the source of the heat.
While the CPU core on an Athlon64 is slightly larger than the P4 core, it is still much smaller than the metal CPU Cap that covers it."
It tells you to spread the Arctic Silver 1,2, and 3 on the bottom of the heatsink, not on the processor. For Arctic Silver 5, one should not even be applying compound to the bottom of the heatsink, not to the processor. Thus, no spreading should be involved.
And no, it won't destroy your cpu because the one I'm using right now works just fine.
