Question 45x360 or 30x420?

[lazo1999]

I have aThermaltake core P3 case and i can fit any thickness rad, either 360 or 420. I plan on a custom loop and radiator choice seems kinda tricky.. I have a 3600 cpu, but later i plan adding my 1070 gpu in the loop, or even upgrading to 2070.
So my question is in title, i am between alphacool's xt45 360mm and st30 420mm and can't seem to find any review for the 420, so I cant decide. Since both are capable enough, i care about acoustics, having in mind that the 420 one is cheaper @74€ and 360 @82€

If you care about the noise, you can get away with thicker radiators and slower moving high static pressured fans. Meaning the XT45 360's paired with a Noctua high static pressure fan.

I would also be open to the ST30 but for it's thickness I'd be running faster rpm fans in spite of having the same static pressure. FYI, I own the Aquacomputer AMS copper rad - it's so thick that I didn't need to add a fan shroud to negate the motors dead spot.
