Antec Nova Computer case Fan 12 cm Black 3 pc(s)

PWM 3-Phase Speed ControllerIncluded three-phase PWM speed controller allows you to switch modes according to different hardware environments and scenarios. Under all 3 modes Nova is able to stop operating when PWM signal is below 6%.P-Q curveThree-Phase Six-Pole Drive Motor- Greater output power and torque. Fully utilizes electrical energy. reducing energy loss.- Better starting performance. Capable of quick start-up and reaching rated speed. improving operational efficiency.- Less noise and vibration. Reduces mechanical friction and electromagnetic interference. decreasing noise and vibration.- Precise PWM closed-loop design. Designed with speed compensation function. unaffected by air resistance. enhancing heat dissipation efficiency.Metal Shaft- Enhances structural strength.- Improves reliability and durability.- Superior dynamic balance.Neodymium MagnetA strong neodymium magnet is placed at the bottom of the fan frame. perpendicular to the shaft. This magnetic structure effectively mitigates displacement due to centrifugal force during high-speed operation. thereby reducing fan vibration and ensuring more stable fan operation.Dustproof DesignDust-proof structure encloses the internal drive components. preventing entrance of dust or debris corroding electronic components inside. thus extending the lifespan of the fan.Exterior Geometric RibsOverall structural enhancement strengthens the fan frame rigidity and reduces resonance.Recessed design at the four cornersThe contact area between the fan frame and the corner is only 7mm wide. reducing by 72%. which significantly reduces resonance and noise.Vibration-Absorbing & Anti-Noise Pads8 anti-vibration rubber pads efficiently reduce vibration and noise.Hexadecagon Fan FrameExtremely Minimal Fan Blade ClearanceThe clearance between fan frame and blades is minimized to 0.5 ± 0.1mm to increase the effective cooling area. avoids fan backflow and enhances air pressure.9 Curved Blade for Optimized AerodynamicsCFD (Computat
