I think the main reason for the droop is not the lack of cooling. It is because it slows down so much that the die swell is much less, so the filament tension is less. You could try not slowing down and turning the fan on for just those layers instead. I have never tried a fan on ABS with a heated bed. I don't even fit the fan on my production machines.
Activate Cool: Checked Full Fan Speed (0 - 255): 255 Do Not Use Fan Before Layer (integer): 1 Maximum Layer Time for Fan use (seconds): 5.0 Full Fan Speed Below Layer Time (seconds): 5.0 Maximum Cool (Celcius): 0 Minumum Layer Time (seconds): 5.0I have produced a very good result but fan-only is not quite the solution, you do need to set a minimum layer time and 5 seconds appears to be acceptable.

Read the Technical details above regarding Filament Diameter oversizing (e.g. 2.96mm --> 3.015mm).

I don't know how you can print 0.4 by 0.6 in PLA with a 0.4 nozzle. It doesn't have enough die swell. Are you sure you haven't accidentally increased the nozzle aperture?

I will have a go with this over the weekend as I want to print out another part cooling fan mount. I'll get back to let you know how I got on.
