Noctua NF-A14 5V PWM 140mm Cabinet Fan (Single Pack)

Long Description

• Award-Winning NF-A14 Design
Based on Noctua’s globally acclaimed NF-A14 architecture, this fan has earned over 100 international awards for its outstanding efficiency, airflow performance, and acoustic excellence.

• 5V PWM Optimized for Special Applications
Designed specifically for 5V power environments, the NF-A14 5V PWM is ideal for USB-powered devices, custom projects, network equipment, and low-voltage PC cooling applications.

• Wide PWM Speed Range with Zero RPM Support
Offers a smooth speed range from near-silent low RPM operation up to 1500 RPM, allowing precise airflow control while keeping noise levels extremely low.

• Flow Acceleration Channels for Higher Efficiency
Advanced Flow Acceleration Channels on the impeller reduce airflow separation at blade tips, improving efficiency and minimizing vortex noise for smoother airflow.

• AAO Frame for Optimized Acoustics
Noctua’s Advanced Acoustic Optimisation frame integrates anti-vibration pads, Stepped Inlet Design, and Inner Surface Microstructures to maximize airflow while reducing noise.

• Stepped Inlet Design for Better Intake Performance
Creates controlled turbulence at the intake side, improving airflow attachment and suction efficiency, especially in restricted or enclosed cabinet layouts.

• Inner Surface Microstructures for Reduced Noise
Suppresses airflow separation on the blade suction side, resulting in lower blade passing noise and improved pressure efficiency.

• Integrated Anti-Vibration Pads
Soft silicone pads minimize vibration transfer to the cabinet or chassis, ensuring quiet operation even at higher speeds.

• Custom PWM IC with Smooth Commutation Drive (SCD)
Equipped with Noctua’s NE-FD3 PWM controller, delivering ultra-smooth motor operation and eliminating PWM switching noise at low speeds.

• Premium SSO2 Bearing for Long Life
The advanced SSO2 bearing ensures exceptional stability, reduced friction, and long-term durability, making the fan reliable for continuous operation.

• High Airflow with Low Noise Output
Delivers up to 140.2 m³/h (82.52 CFM) airflow with a maximum noise level of just 24.6 dB(A), achieving an excellent balance of cooling and silence.

• Ideal for Quiet & Custom Builds
Perfect for silent PCs, HTPCs, USB-powered cooling solutions, DIY projects, and applications requiring dependable 5V PWM cooling.
