Best case fans for corsair 250d?

[RETCHEDBEAST]

Using the corsair 250d for my next build and I'm wondering what's the best fans to use for this case? I'm planning on using a h100i as my cpu cooler on the side with side intakes and need a front intake too. Would like them to be silent but efficient and PWM and black! And no LEDs please.
2 x 120mm side
200 or 140 front, which is better?
Thanks
