First Print with ABS and bad overhang

Hi there,

I printed a while with PLA and I'm now trying to print with ABS on my Prusa i3 mk3s. I'm trying to print marvin till I get the perfect result. But the overhang looks awful and I don't know where to problem is and how to fix it. I tried a few different temperatures on the bed, on the printer, also different configuration on the cooling fan.

The best result I got with 240° on the Extruder and 100° on the print bed. As far as I know, I should disable the Cooling Fan on ABS so I disabled it or tried to use it only on bridges. But nothing helped.

Here a are all settings, hopefully it will help:

I know, most of the infos are useless 😉 But better post too much info, than too less.

Here are a few pictures of the awful results (I only add the links to imgbb):

Any suggestions where the problem is and how I can fix it? Does it have to do with the room temperature und cooling of ABS? My last printer was completely closed and I never had such Issues with ABS.
