Pretty much how it is done everywhere else. Problem is getting accurate temps off the CPU.

As I see it, results of die sims are not "inaccurate" as you put it, rather the other way around (results of tests done on actual cpu's are more likely to be 'inaccurate'). I guess this topic has been talked about enough around here though...

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.

2) didn't know that - calibration with each water block base plate would then be necessary I think
|
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.

4) ok (though we haven't fully explored the cost yet). If it is cost prohibitive/ineffective, then we need different sized die sims? And still requires ~5mounts to ensure accuracy.

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.
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.
