Noctua’s NF-A12x25 G2 is game-changing, offering the quietest, most refined fan we’ve ever seen. In our testing, it delivered whisper-quiet performance and managed an impressively huge amount of airflow despite running at very low RPMs.

Managing such big airflow despite not needing to spin fast to accomplish it means it’s also not a very turbulent fan, which translates to chart-topping performance when installed on a radiator or behind an intake mesh. In fact, it’s the only fan we’ve tested thus far that ran quieter on a radiator than when suspended mid-air without any load.

In addition to pulling off airflow miracles, the NF-A12x25 also offers a seriously advanced internal hub, featuring Noctua’s refined, tried-and-tested SSO2 bearing, a new 3-phase etaPERF motor, and a new PWM controller with SupraTorque functionality. This sounds like a bunch of marketing talk, but after testing the fan, we can tell you with confidence that it has zero audible mechanical noise.
