Otherwise, The White Water and the Cascade may suffer a marginal performance hit (or boost?), from a 10 by 10 mm die, but is it significant?
The various hot points of a CPU core really can't be simulated, because there's no data available on that. I believe that it's sufficient to simply state that the heat die must generate "X" Watts. I don't believe that any waterblock is intentionally designed to take advantage of the distribution of the heat load, within the die.

Well, if your goal is to simulate a given core and how a waterblock reacts with it, the P4 has the IHS with its extra tim so why not use one. Not too many people are removing the IHS and running any waterblocks on the die itself (there are a few exceptions I've seen). Now that just doubled the workload for an all in one tester hehe, test with bare die to simulate older AMD, then test with IHS for P4 and future AMD cores and make a new die for that too while you're at it. Who in their right mind is going to take on such a task? So I guess in steps your alliance and says it's alright to cut corners, just not too many of them?
From what I've seen you discuss so far I get the impression that you will certify (and I use that term loosely) using a low resolution, shaky accuracy, not so steady state water temps, and now a die size that does not match any processor.
