It comes with a Y-adapter to connect a second fan on the same mom card connector, a Low Noise LN adapter to reduce speed and noise.
And the choice to secure the fan in your case, 4 screws and metal fasteners 4 anti-vibration rubber.
Given to 19.8 dB (A) Max 1200 RPM with an air flow rate of 100.6 m2 / h.
It was announced to 16.9 dB (A) maximum 900 RPM to air 76% with adapter LNA (Low Noise).
The NF-P12 model without PWN with ULNA adapter (Ultra Low Noise) rotates at 600 RPM to 12.6 dB (A) but with 49% airflow. CPU Kühler 120 x 120 x 25mm 130RPM 19.8dB (A)
So I would have enjoyed having a ULNA adapter, but as it is a PWN, it is supposed to according to the temperature drop below 16.9 dB (A), knowing that below 17dB (A), be considered silent, the perceived level of silence will also depend on other fans of your pc and acoustic insulation of your housing ...
Otherwise the cooling performance is at the rendezvous.
