Acoustic Expression: Silence
The Neptune AN fans, integrated with innovative aerodynamic blades, maintain efficiency while sustaining a silent, tranquil environment. The 8-individual-ARGB-LEDs enrich the PC’s overall visual aesthetic.

The Neptune fans underwent rigorous testing, fortifying a strong pressure-to-airflow P-Q curve. The critical middle section indicates that the Neptune fans possess high static pressure and airflow that outperforms the competition.
Besides enhancing speed, the Neptune series creates a more balanced performance, which includes reducing noise. Turbulence, resonance, and pitch from air dispersal were all taken into consideration. InWin dissected the fan's anatomy to produce these silent high static-pressure fans.
InWin’s Semi-Anechoic Chamber’s background noise level is at 17 dB(A). The sound test distance between the fan and the microphone is 1 meter.

Without airflow leakage
Regular Fan
With airflow leakage
Experience quiet cooling and efficient airflow with InWin’s signature Turbine Blade design. Molding the fan blades into the frame creates a more concentrated airflow, preventing air leakage and irritating noise pollution.

Neptune’s fan blades are angled slightly to ensure the airflow is channeled in a more focused stream. This tactical design allows the static pressure to increase.
The Neptune case fan series PWM initiates at an immediate 900 RPM. This will provide enough airflow to cool loading PC systems while producing an extremely low noise level at 17.2 dB(A).
