Noctua NF-A12x25

Pros

• The Noctua NF-A12x25 (25mm thick) pushes roughly 40-50% more air than the NF-A12x15 (15mm slim) at similar noise levels. At the same RPM the slim fan is slightly quieter just because it moves less air, but if you match airflow output, th...
• Noctua NF-A12x25 the gold standard, quiet and high performance
• If you're looking for fans that run extremely quiet, look at the Noctua NF-A12X25 or Phanteks T30. At low speeds they're some of the quietest on the market as well as having excellent sound profiles, and retain a high level of performanc...
• Yes, the NF-A12x25 [Chromax.BLACK] are some of the best fans on the market still, especially if you're sensitive to certain noise frequencies.
• Apart from just being very good performing Noctua fans with low noise, their real super power is that the noise they *do* make is generally easy to ignore even in challenging scenarios.

Cons

• The Noctuas are relatively pushy even at silent speeds, but neither those can defy physics, in terms of noise, once the RPMs go up, but if they go up there, maybe only the Be Quiets are close in terms of noise.
