    I've been having issues with overhangs. Best example is the Benchy model. The bow always comes out looking not so great. My fans ( 2 ducted fans) are at 100% and I have played around with speed and temperature. Any body have any tips for overhangs?

    ^ Good resources ^ But also:

    In my experience you need to
    A) Use the lowest possible extrusion temp
    B) Use the lowest possible bed temp (radiated heat is a problem too)
    C) Use an external fan if possible
    D) Put the overhanging side facing the external fan
    E) USE SMALLER LAYER HEIGHTS (down to 0.1 if possible)

    For step C I use an old 140mm server fan hooked up to a variable power supply set in front of the printer, the more air the better. The only problem with this method is that if your print is large and flat you'll likely get warping/adhesion problems with the bed.
