-> in the pursuit of every last mhz, did Stew use a die sim ? what die temp was used ?

you guys need your heads examined

no die temp is needed to design a cooling solution, the IHS is fine
the real problem remains that of the applied power when using a CPU as the heat source
hmm - i think you may be misunderstanding the issue people have with using the IHS temp (or maybe i am....)

aiui the issue is not that a better source is (or more accurately isn't) available on an intel CPU - but that:
a) the purpose of cooling is to cool the die, not the IHS...
b) it is possible (probable?) that there is no fixed relationship between the temp of the die (or whatever portion most requires cooling for a given use, since the .pdf confirms that it will vary) and the IHS temp (which is taken at a particular point at the centre of the IHS iiuc)
c) that being so it is possible that the more efficient (at cooling the die) of 2 blocks might give the same or worse IHS temp as a less efficient block

of course as old bill might have put it:
