Cover the tip of your finger with the saran/sandwich bag.
Spread the paste outward, maintaining a modest amount of pressure.
Work slowly, from center out, with slow spreading motion.

Spread until the CPU is covered in a reasonably uniform layer with no big chunks of paste missing. Then carefully attach your CPU cooler or waterblock.

2 reasons I have used this method over the one-blob-in-center method:
1) If your heatsink retention bracket isn't particularly strong, it will not spread out the thicker thermal pastes well, especially AS5 which is pretty viscous/thick.
2) You ensure UNIFORM coverage of the CPU, ensuring contact with the entire width of the CPU's IHS lid.

A lot of people say that you only need thermal paste over the die: This would be correct if the area of the CPU IHS that got hot was ONLY directly over the die. Unfortunately for that reasoning, thermodynamics says that the material copper is a very efficient conductor of heat, hence the reason CPU manufacturers use it to make their CPU lids. The entire width of the cooler pulls heat off of the die. Now will it work both ways? Yes it will. But I believe this spreading method is the best way to ensure a nice even thin layer, with great 100% (or close) heatsink-to-CPU contact.

It has yet to produce erratic temperatures. Now it COULD BE that I am just amazing. But I doubt that very much, because I am actually an idiot so if I can do this 8+ times and it never EVER fail, it must be that the method is just solid.
