I even thought about it, after a couple of weeks using it.
depends on the size of the core, or if it is covered by that cap.
I think the dot, then dropping the HS on is the best method for cores with the cap over them. P4 or newer AMD.
I say that since its more concentrated above the core. Spreading it around may make the particals be spread out uneven.
Though, for the other cores without a cap, then you have to spread it over the core. Only thing bad is not having a thin layer, and it gushes over the edges when the HS is put on. So some heat get trapped on the sides of the core. To where on a cap, as long as it is centered right, should do the best job.
