Many common fan series use the same blade geometries across all performance ranges, whether in high-performance applications with high speeds or in low-noise segments with low rotations. However, different designs are better suited for different purposes, which means that conventional fans often do not perform optimally in at least one scenario—they are either unnecessarily loud or underpowered.
With the NF-P12 fan, the Austrian fan and cooler specialist Noctua has proven that even at higher speeds, low noise and smooth operation are possible. This makes the fan still a great choice for use in cases where powerful hardware needs to be quietly cooled. The NF-P12 has also been a solid option for CPU coolers due to its high airflow, though it lacked the ability to be automatically regulated via the motherboard's PWM control.
This gap is now filled by the NF-P12 PWM, featuring Noctua's own NE-FD1 PWM control chip. Like the regular NF-P12, the PWM version features the "Nine Blade Design" and "Vortex Control Notches." The staggered notches on the fan blades distribute the noise emissions over a broader frequency range, making the fan less irritating to the human ear. The proven SSO bearing is also used to make the fan even quieter, while ensuring excellent long-term stability.
The 120 mm fan comes with a "Low-Noise Adapter" (L.N.A.) that reduces the maximum speed from 1,300 to 900 RPM at a maximum of 12.6 dB(A), making it easy to adjust the fan to your specific needs. Additionally, the package includes four standard fan screws, four decoupling mounts, a 30 cm PWM extension cable, and a Y-splitter cable to connect two fans to a single motherboard PWM connector.
