Withdrawn Attachment - Errors.Done Something Stupid and Can't Find *

First guess at AMD 3000+ model.
Used experimental Parabolic Flux model which for the moment has forced me onto Circular dies
Modelled for TIM 1 of 0.06c/w per cm^2 and the old Intel(ish) 0.25c/w per cm^2 TIM, linked by Marci link
Guess AMD probably use a TIM intermediate between 0.06 and 0.25.
Tendency to degrade as in article? Easier to use a bigger than 101mm^2 die ?
More to be added to attachments: 1mm HotSpots on far-surface of 0.5mm thick 148w/mK slice of Silicon
w/o IHS model

* Edit:
The root of the prob which caused withdrawing of attachment for my model AMD3000+ :-
Get different solutions when considering "bp +IHS" as one entity and calculating separately .
e.g Apogee(34diam x3)+TIM(0.06c/w*cm^2) + IHS(34diamx1mm) on 11.34 diam Source.
At h(eff)=43788 and IsoFlux
Consider as continuous 4mm or continuous (3+1)mm then adding TIM get: R(water -> far IHS surface) = 0.112777+0.006607=0.11938
Considered as (3mm with h=h(eff)) + (1mm with h=1/(Rbp+1/h(eff)*A+Rtim)*A get: R(water -> far IHS surface) = 0.156659

Still hoping for comments on "Anyone know undercup bp thickness of the Storm G4 ?
Have upped from 0.7625mm to 1.2625mm following Cathar's "Storm's bp is substantially thicker than 1mm" (link to page).
Is this right?"
