The best way to spread AS5 is to not spread it.
You put a drop worth on the middle of your cpu. Apply the heat sink. The next day take it off and your entire cpu will be covered. But if you need the as5 manual its here: http://www.arcticsilver.com/arctic_s...structions.htm
I put more than a drop on my cpu, a steady thick line down the middle of the cpu. That was it. I went to change my heat sink and it was thick across my whole cpu and started to run down the side. I just couldn't belive how little they told you to put in the instructions. They don't lie.
