Noctua currently has no 140mm fans that are competitive with Arctic P14s - their NF-A14 is a much older design than the NF-A12x25, and the A12x25 is barely better than the Arctic P12. The P12 and P14 are the same design in different sizes, so the P14 should then noticeably outperform the P12, unlike the NF-A12x25 and NF-A14. (Noctua themselves marketed the NF-A12x25 as performing the same as or better than their 140mm offerings ...). To me, it sounds like that fan swap would double your AIO's price for an increase in noise (as you're exchanging two fans for four, even if they're quiet that noise adds up) and at best performance parity, at worst a drop. And as [USER=20979]@ten13th[/USER] said, Noctua doesn't have any 140mmx15mm fans.I really like Noctua, and I'm really looking forward to seeing them bring the NF-A12x25 design to 140mm fans, but that's still a ways out.Speaking as a previous Noctua diehard who recently swapped to a single 280mm rad with two Arctic P14s: buying an Arctic AIO and swapping out the fans would be an incredibly stupid thing to do.
