So far I have seen: 392, 391 and 388 W/m*°C which is instantly an uncertainty of 1% How does one handle error summation? With what I work with they are added quadratically ie E tot= sqrt(E1^2+E2^2...) but that may not be applicable in this case.

Ideal would probably be to measure the dT of the assembled device with known heatloads.
The resulting date would encompass both the thermal conductivity of the particular device and shadowing effects.
