You are not following what I am saying I guess.... What are water blocks designed for? CPU's. Why on earth would anyone care how a block performs on a die sim that doesn't replicate a CPU? There is just no reason to have or know this information as it doesn't pertain to anything. This is why die sims results are not accurate because they do not tell us the needed information for which the water block was designed for. The water block was not designed to cool die sims. The data collected from die sims (I have plenty of it from my own) doesn't tell us how the block performs on the platform it was designed for.

Well, so far all the data I know of shows that heat dies replicate bare cpu dies just fine. There is only disagreement/ambiguity when you talk about cpus with IHS. This data you speak of that doesn't tell us how blocks perform on cpus, are you talking bare die or not?
Maybe there should be two methods of testing to replicate the two areas of usage...

Getting the exact same focus over and over is hard to do. Makes mounting the block to a die sim seem less of a challenge in fact. Power changes with focus.
Well our little 80watt laser with a 100watt tube cost $45,000 about 5 years ago. And it was setup just to cut and engrave. Nothing fancy. To get setup properly I would suspect in the $100,000+ range.

both of these seem to make this method extremely difficult and cost prohibitive.

Another thing I havn't figured out is were you intend to put the temp probe(s)? Can't put it in the area the laser is focused on yet that area is were the probe needs to be.

was addressed in the first post, point #2. But I was not really convinced this would be the best, as Annirak is proposing to put it in the laser. IF this method was used a probe inside but close to the heated surface of a copper calibration block would have to verify that the probe in the IR beam was reading temps appropriately, however I doubt it would.
Could put it just on the outside of the area of focus?
