How to use different infill in different areas?

[paoletto 3]

I am trying to print a model that needs strength in some areas, but not everywhere not to make it weight a lot.
So i wonder if it's possible to set up the slicer to use different infill parameters like in a specific area (spherical? cubical? idk).
I'm relatively new to cura/3dprinting so i hope this is going to be possible.
I read that variable line settings are still in the work so i do not expect that to be possible. I suppose variable extrusion temperature is also not possible? (i think it would help to print a bit hotter in this area to make the lines stick together more).

I'd be also interested in using the cooling fan only in selected area of the print (where overhangs are to be expected) and leave it off in the rest. Is this possible?

Yes.  You can add a support blocker.  Move it and scale it to the size you want.  Then select "Modify settings for overlaps".  The 3 default settings are fine, just add "Infill Pattern" and set it to what you want.  You can also add "Infill Density" and have that different in the overlap area as well.

Here the model has a Grid infill at 20%.  The overlap area of the support blocker is "triangles" at 10%.
