It might sound funny but it works. The surface of a CPU or a heatsink is
never entirely flat; if you place a heatsink directly on a CPU, there will
be tiny (invisible) gaps between the two. Since air conducts heat poorly,
these gaps have a very negative effect on the heat transfer. Therefore, an
interface material with a high thermal conductivity is needed to fill
these gaps, and thus improve heat conductivity.
Sudocream is a compound of zinc oxide and silicone. The temperature
difference between using a zinc oxide compound and other more exotic
compounds is very small. See the thermo interface material test on
