I can find the thermal conductivity sample values in this table
http://upload.wikimedia.org/wikipedia/commons/1/1e/Thermal_conductivity.svg
I don't know however, how should be measured the thermal conductivity across materials?
For an example does the thermal grease conduct heat to the copper sink with the value for copper, or the value for thermal grease (lower)?
Also, in a cooling system of consequently related elements (CPU, grease, sink, air) is the overall conductivity equal to the lowest value (like in electricity resistance) ? Or is there some formla of calculating that?
(which is practically the same question
)
