New case fans needed.

[Dlaw]

I need new case fans, one or two are starting to make a lot of noise and I don't like it. Was thinking I'd grab just 3 to replace the ones I have now, and wait to add more when I water cool this beast next year. So, I need 3 140mm fans that can produce the most airflow while being silent.

Noctuas NF-P14s redux 1200 or 1500 rpm fans would be a great choice. Or their NF-A14 PWM.
Those are quiet and move some good air. I have one of the 1500rpm first ones as an exhaust out of the back of my rig and it's great. I have the 120mm versions pulling air in the front and they're great too.
