I see you listed your fans and are running lots of Thermalrights. I actually just finished an excel spreadsheet comparison of 140mm fans
I have compared the following:
-Fractal R2 (case stock fans)
-Corsair AF140 Quiet Edition
-Aerocool Shark Black
-Scythe Kaze Maru 2 Slipstream
-Noiseblocker BlackSilent PK-2
When comparing these models, the stock R2s aren't actually that bad. They are all pretty good. Those Aerocool Sharks would be pretty good for the front intake. They have the highest rpm at 12v compared to the others but they have significantly higher airflow/pressure at that speed. Even at low 7v they are impressive due to the 15 fan blades. And if I run intake on controller and turn them up for gaming, well noise wouldn't be too much of an issue considering that's the time when the system is going to be loudest (i.e., gpu). Also the BeQuiet is a great company, great service, long warrant, and reputable. It's so hard to choose!
I see you have the X-Silents and are going for the TY-147. My only concern with the circular Thermalright 140mm fans (w/120mm fittings) is if they would actually fit alright in the R4. I am assuming they do now if you use them in the Arc Midi.

-Looks like 2x TY-141s don't fit in front intake (unless modified). So could put the two stock R2s in the front then three TY-140s (bottom, back, top/back).
You're correct, the TY-14X series don't fit in the front intake, unless modded, this is however rather easy to do. They might actually fit easier within the R4 than the Arc Midi, due to the different front fan holes in the R4 (while the Midi in only a holding frame without any hole): you'll probably be able to screw in them in, else a 120-140 adapter would do the trick, and probably reduce noise as well (less turbulence).
I wasn't impressed by the stock R2's, they are rather noisy for my taste, and the motor has a clicking noise unless turned down to 8V or less.
All the fans you've listed are indeed very good. I moved from X-Silent to TY-147 fans because the TY-147 has, IMO, a better control range. Both fans have a somewhat similar starting RPM range (close to 500 RPM), but the TY-147 pushes a bit more air. And it looks cool
However, the noise quality of the X-Silent is slightly better, it has a deeper and smoother tonality when turned 750 RPM or higher.
