Noctua fans are already justifiably famous for low noise and long service, but the NF-P12 adds a number of innovations to move the design to new performance heights - and they say they have done it without compromising noise. These include a pressure-optimized Nine-Blade design, SC (Smooth Continuous) Drive to reduce torque variations, and a new SSO (Self-Stabilizing Oil-pressure) bearing for exceptional quietness and long-term stability.

Perhaps the most interesting innovation is the notches you see in the blades of the above fans. Noctua calls these Vortex Control Notches. These notches are "psychoacoustic optimizations", staggered to allow the fan to reduce noise levels from the fan.

All of these fan innovations have one real goal in mind: to run the NF-P12 fans faster without introducing more noise. In the end, such optimizations can skirt laws of physics but they can't really be broken. For improved air-cooling, you need to remove heat efficiently with a great heatsink design, but that heat must be dissipated with sufficient airflow.

Noctua believes their current top heatsink design, which we first saw on the NH-U12F, is as good as anything on the market. They have coupled that heatsink with the NF-P12 fan and they claim this combination will move them into serious competition at the top of our performance charts while still maintaining lowest noise. Does this work; has Noctua found a way to accomplish both highest performance and incredibly low noise? This review of the Noctua NH-U12P will find out if Noctua has accomplished the seemingly impossible.
