Verdict
Noctua NF-A12x25 PWM chromax.black.swap
9 / 10 Expert Rating
Same excellent A12x25 performance in a colorway that fits black-themed builds without a sticker or paint job.
Noctua NF-S12A PWM
8 / 10 Expert Rating
An excellent quiet airflow fan for open cases, but expensive per-fan for how little static pressure it offers.
