(I did some testing with a 0.625in. inlet on a 462 and it was TERRIBLE)
Until I learn otherwise I equate the DAI cooling to the "thrust" on the die area . From simple "rocket science " I would expect this to be maximum wth a nozzle the same size as the die .For a 10x10mm die,possibly, a convergent/divergent 10mm/11.5mm diameter nozzle (ye old tapered barb) would be optimum - http://www.grc.nasa.gov/WWW/K-12/airplane/ienzl.html
