If only a 120mm fan will fit, consider a GT AP-14 or AP-15, or an Ultra Kaze 2000 rpm. You can always undervolt it with a single-channel fan controller. A UK2K at 5v runs 1050 rpm. A UK3K at 5v runs 1250 rpm, so simply rewiring the fans won't quite do.
To expand on what chinesethunda says, to evacuate your case properly downstream from a cpu heatsink, you must have adequate cfm to evacuate the case as well as suck up all of the exhaust from the cpu heatsink, and it must be driven with sufficient static pressure to overcome the resistance of the rear grill. And that is why I got rid of mine.
There's space for 140mm. Maybe for the moment I'll remove P14 from the top and put it on exhaust. And in the top will go fractal 140mm.
In Arc Midi there is also space for 180mm fan in the top, maybe it'll be better with 180mm blowing inside ?

I'm almost convinced to cut the damn thing out
