I ended up switching back to the stock fan because of some layer lifting as well. I think the little MPSM fan has just too little air flow for this and the stock fan directs it a little better. I've posted an updated make with a Benchy using identical Gcode using first the new shroud and then the stock shroud. The stock wasn't better in all ways, for example the text on the bottom looked better with the new shroud, but over all not as good.
