Review on 🌀 Noctua NF-A15 PWM: Premium Quiet Fan, 140mm, 4-Pin (Brown) - Ultimate Cooling Experience! by Kio Walker ᠌

The set is very pleasing Good balance between airflow and static pressure On medium and low - perfect At high, a very noticeable rustle of the blades (the engine is silent) In the open case: the sound is nasty and loud, at the beginning I was very upset Closed: Magic! Only the movement of air is heard, apparently it has a special tone Different pros: Excellent performance, very quiet at medium speeds, silent motor, directional airflow, complete Different cons: The aerodynamics of the cavities creates perceptible noise Non-standard dimensions and location of mounting holes
