I found bridging to be particularly challenging for these devices, and I have a 7" desk fan next to the printer I turn on after the first layer finishes. Besides preventing the bed from ever getting over 62C and possibly reducing layer adhesion I haven’t seen any negative effects.
I have also fought some slicer’s bridging gcode generation - I love Simplify3D, but I think Cura generates better bridges when the Advanced Bridging options are enabled.
Also, check out this for other things I went through to optimize the prints:
My new blowers showed up today, this weekend I’m planning on increasing the part cooling, the built in part cooling fan is comically underpowered.
