Billions if not trillions of transistors and integrated circuits have
been fastened to what were called heat sinks then and whatever the
marketing folk want to call them now.  All benefit and even require the
thinnest of heat transfer pastes, the sole purpose of which is to fill
the microscopic space between the surface of the electronic component
and the heat dissipator. (A minimal amount because there's no more
heat-conductive material in the immediate vicinity than the heatsink
itself. Or less conductive one than air, which can be there as one or
more bubbles that can't escape the paste/grease as the surfaces are put
together. )

 No mfg wants failure. Thousands of snake-oil specialists want you to
buy their paste and justify nutso prices by reminding you to use the
physics-based minimal amount. Installation technique probably results in
more variation in results than differences in the grease/paste.

This list is not geeky enough for someone to insist that the superior
counterexample to the above would be gold foil pressed under high
pressure to each surface. But you can probably find such a claim
somewhere, And others checking it out. 

Major flies in the ointment, are particles large enough to act as
uncrushed boulders keeping the surfaces apart, and the fact the the
mating surfaces MAY not be or REMAIN parallel in use.

     On: [OS2HW] Heat gook
     [echoed below, at least in part]

--------
I touched my Thermaltake CPU cooler while watching the "health meter,"
and the temp jumped.  I pressed it against the CPU and it dropped 10 or
15 degrees.

There is dark grey substance spread on the bottom of the cooler.  It is
thin, pretty hard and doesn't impress me as a good transfer gook.

Is the kind of thermal transfer gook to use important?  Should such
stuff be relatively soft?  Like wax?  Harder - like this stuff?  I know
there are silicone gooks and some that have metalic powder.  Any
recommendations?  Do any local sources normally carry it?
