this CANNOT be true
both in the 'unsanded' state as well as the 'sanded' one
- due to the IHS's flexibility and lack of support away from the CPU area, and away from the IHS's edges
- and note also that once sanded there is a thickness variation to deal with as well
this could all be modeled I guess, but not by me Thanks

Yes it is the "Uniform Flux" case.
However to illustrate that the spreading should not be automatically completely ignored the graphs may serve.
Waterloo do both "Parabolic" and "Equivalent Isothermal" for circular heat sources sources but not "rectangles with end cooling". I have no intention of pursuing.
