Bested the Tested
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.
The Neptune DN PRO fans revolutionize the industry’s thermal approach by integrating the specialized aerodynamic blade design. These fans balance cooling performance and acoustic suppression. Get ready to experience pro grade cooling!
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.
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 DN PRO fans operate with optimal stability and minimal vibrations. The fans accomplish this after countless dynamic balancing tests and multiple manual tunings.
Unleash the full power of the DN PRO with its three-phase, six-pole motor. High torque provides energy efficiency.
Thoroughly covered with a metal magnetic shield, the motor is blocked from electromagnetic wave disruptions to host a smooth operation.
From the motor rotating, fluid automatically provides sufficient lubrication and stabilizes dynamic pressure. Meanwhile, the copper bearing shield provides balance and stability to keep high performance at a much longer lifespan.
The closed-loop controlled circuit can detect the motor speed and compare to the designated PWM. The self-correcting difference can be precisely minimized down to 1%.
Metallic precision screw threading is pre-applied for easy installation. Customized radiator screws are included.
Both fan and extension cables are sleeved with braided nylon for better overall protection and appearance.
