The NF-A8 impeller options suction aspect Flow Acceleration Channels. By dashing up the airflow on the essential outer blade areas, this measure reduces suction aspect circulation separation and thus results in higher effectivity and decrease vortex noise
Noctua’s AAO (Advanced Acoustic Optimization) frames function built-in anti-vibration pads in addition to Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, each of which additional refine the fan’s efficiency/noise effectivity
Noctua’s Stepped Inlet Design provides turbulence to the inflow so as to facilitate the transition from laminar circulation to turbulent circulation, which reduces tonal consumption noise, improves circulation attachment and will increase suction capability
Integrated Anti-Vibration Pads comprised of extra-soft silicone reduce the transmission of minute vibrations whereas sustaining full compatibility with all normal screws and different mounting programs
The NF-A8 options the additional optimized second technology of Noctua’s famend, time-tested SSO bearing. With SSO2, the rear magnet is positioned nearer to the axis to offer even higher stabilization, precision and sturdiness
Supporting totally automated PWM pace management, the NF-A8 PWM makes use of Noctua’s novel, customized NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) expertise.
The NF-A8 PWM is equipped with a Low-Noise Adaptor (L.N.A.) that reduces the utmost fan pace from 2200 to 1750rpm. The L.N.A can be utilized both to run the fan at a set pace of 1750rpm or to cap the utmost pace when utilizing automated PWM management
The fan’s brief 20cm main cable minimizes cable muddle in typical purposes whereas the equipped 30cm extension gives prolonged attain when obligatory.
