For better overhangs the most important thing is 100% fan. So if the overhang is below 5mm from the bed you need to adjust the cura settings. Not as critical - it can help quite a bit to print slow. 20-35mm/sec. Also having a 2-pass-shell helps (make shell thickness 0.8). Also if layer thickness is too thin or too thick this might affect things - not completely sure about this detail - but anyway .08 is a reasonable choice for layer height.

So try .8mm shell and print at 20mm/sec just for an experiment to see if any better.

Other hints about other printing issues (not overhang) are here:
