FF Creator Pro with slic3r - small areas melting

This seems like it ought to be fairly straightforward for someone who has the slic3r settings dialed in for a FF Creator Pro. I'm using ABS and have pretty good prints now using the settings I have though experimentation. I know ABS is more challenging than PLA but I feel like I'm so close to having this work just right - If I can just get it to stop melting the top small areas. BTW, this is the right extruder - the left extruder prints better and I think that's because the fan shroud is much closer. Using the fan makes a big difference for me.

Anyone figured this out?
