I hadn't considered it yesterday, but today, I am still somewhat stymied by the results on my machine: a shroud in either position seemed to raise temps. I was considering doubling up fans next, i.e.
Fan | Fan | H50 (intake)
probably with & without shrouds, but I think I should add double shrouds in there, too. Hey, why not test all these differences, it's pretty fun. Though I am a bit surprised at how different the results can be on a "case by case" basis, literally.
I wish I understood better why my results with a shroud were not better. I am considering starting over from scratch, tesing very methodically and being mindful of modifying just one factor at a time, i.e. "single fan, push, intake", "single fan, push, shroud, intake", etc.
Also perhaps using a different stress program for calculating max temp -- although OCCT makes it really hard to compare, since the default graphs/images are so handy.
