Neptune Pure AN120P

Unveiling the Neptune Pure: Pure Serenity

Experience the pristine, pure white elegance of the Neptune Pure fans and elevate your PC's aesthetics. Quiet, efficient, and tested for high static pressure, they're perfect for your silent setup.

Bested the Tested

The Neptune Pure fans underwent rigorous testing, fortifying a strong pressure-to-airflow P-Q curve. The critical middle section indicates that the Neptune Pure fans possess high static pressure and airflow that outperforms the competition.

True Air Benders

Besides enhancing speed, the Neptune Pure 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.

Turbine Blade Elegance

Discover the beauty of silent cooling and efficient airflow with InWin’s Turbine Blade design, now in a pristine finish. Crafted to concentrate airflow, it eliminates air leakage and noise pollution.
