I've heard the surfaces of both a CPU and a heat sink aren't
perfectly flat (though you'd have to look at them with a microscope
to see any imperfections in the shape) - so the surfaces aren't
making full contact with each other. Thermal paste is supposed to
fill the gaps, which helps transfer heat.
yeah but these are precision machined products, so i think of possibility of that being true might be slim. like i said in another post, some false statements became known as truth when it was repeated a lot.
Even if it weren't true, I would imagine that after repeated heating and cooling, the surfaces of a CPU and a heat sink probably don't remain perfectly flat and would probably develop some imperfections in their shape after a while. Kinda like a street or a sidewalk that cracks after a while due to repeated thermal expansion and contraction (though metal isn't as brittle as a sidewalk or a street).

Do you use the ThinkLight much? I like the way it helps to
balance out the overly strong light from the screen and provide *something* over the keyboard work area.

What temperture are you managing for your machine?

Thermal paste is supposed to fill the gaps, which helps transfer heat.The best thermal insulator is a vacuum. Next would be just trapped air. So the paste is an attempt to provide 100% molecular contact to the surface to transfer heat from one material to the other. BUT there is always a bottleneck between two seperate objects no matter what.

I don't use it all that often, but when I do, it's a much
better solution IMO then under-key backlights. I don't know
why, but being able to see my hands in the dark helps. I'm
not a touch typist as such.

55-65c, after running 24/7 for a week. Depends on the
ambient temp and what's running at the time.
