The NF-P12 has been specifically developed for applications such as CPU coolers that demand superior pressure and airflow performance. Thanks to psychoacoustic optimizations like the Vortex-Control Notches, the new SCD drive system and Noctua’s premium-grade SSO-Bearing, the NF-P12 achieves exceptional quietness and long-term stability.

The pressure-optimized Nine Blade Design of the NF-P12 (P stands for pressure, power and performance) has been specifically developed for high-impedance applications such as CPU coolers, water-cooling radiators, power supplies or cases with restrictive fan grills. It achieves outstanding static pressure and high airflow at very low noise levels.
While most conventional 120mm rotors possess seven comparably narrow fan blades, the NF-P12‘s Nine-Blade Design uses nine large, closely spaced blades with a relatively low angle of attack in order to achieve maximum static pressure and high airflow. As a result, the NF-P12 provides no less than 1.68 mm H²O at 1300 rpm, which is something that other fans merely achieve at 1600 rpm or more.

Noctua principally recommends the NF-P12 for the following applications:

• CPU coolers with tight fin-spacing
• Water-cooling radiators with tight fin-spacing
• Power supplies
• Storage solutions
• Cases with very restrictive fan grills and filters
• All applications with significant obstruction to airflow

Pressure-optimized Nine-Blade Design
Specifically developed for high-impedance applications such as CPU coolers, liquid cooling radiators or cases with tight fan grills, the NF-P12 provides superior pressure and airflow performance.

Vortex-Control Notches
Psychoacoustic optimizations like the staggered Vortex-Control Notches make the NF-P12 surprisingly quiet.

Smooth Commutation Drive
The NF-P12’s new drive system reduces torque variations and thereby ensures improved running smoothness.

Self-stabilizing oil-pressure bearing
Noctua’s well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.

Full speed, only thing you''ll hear is the air flowing through these which makes those fan speed adapters useless to make those fan any quieter then they already are. Heck my Power Supply is way nosier then these, so far I order about 10 of these fans and never had to send a RMA.

Alright, it''s not what you think. The Lian Li PC-76 server case has dense grids through which its case fans must push air. I used a Dremel tool to cut out this grid for all the fans to provide unrestricted air flow. What a difference! Six degrees Celsius cooler! And if you do this artfully, it can actually look pretty cool (pun intended!).

A very, very quiet fan. I have two of these on a CPU cooler and it works very well. However, based on other fans rated at the same CFM, my feeling is the air flow numbers a big optimistic. They don''t work well for a water cooled radiator, they just don''t move enough air across the fins to cool well, but it''s still a good fan.

This fan is silent as dead ;-)

I bought two of these to replace a 120x38mm fan in my server case. (the old fan has a rating of 42 dB) They are practically silent. The rubber mounts can be kind of a pain to use if you can''t get your fingers in every corner. The way my case is I had to use dental floss to pull them through the fan''s mounting holes. Overall, I''m very happy I spent the extra money on these.
