Noctua NF‑A14 industrialPPC 24V 2000 SP IP67 PWM 140 mm Fan

The Noctua NF‑A14 industrialPPC 24V 2000 SP IP67 PWM 140 mm Fan is engineered for the most demanding industrial and automotive applications. With a rugged fibre‑glass‑reinforced polyamide design, IP67 certification, and 2000 RPM performance, it delivers exceptional airflow and reliability—even in harsh environments.

Unmatched Industrial Performance and Robust Reliability

24 V High‑Speed Operation & NE‑FD5 Driver

This 24 V SP variant employs Noctua’s NE‑FD5 single-phase PWM motor driver IC, offering inrush current suppression and burst/surge immunity. It achieves full 2000 RPM performance and operates safely in volatile or sensitive electronic environments, ensuring consistent high-power delivery and efficiency. At 12 V PC voltages, it still runs at around 1100 RPM with PWM control for quieter operation.:contentReference[oaicite:1]{index=1}

IP67 Ingress Protection & Durable Build

The fan’s motor and PCB are fully encapsulated in thermally conductive resin, earning IP67 certification—resistant to dust and immersion up to 1 m. The impeller and frame are made of fibre‑glass‑reinforced polyamide, tolerating temperatures up to 140 °C, ensuring maximum durability in extreme conditions.:contentReference[oaicite:2]{index=2}

Signature Noctua Engineering for Efficiency & Quietness

Award‑Winning NF‑A14 Design

Built on Noctua’s internationally recognized A‑series design with Flow Acceleration Channels, the fan delivers higher static pressure and airflow while reducing vortex noise. The AAO frame and integrated anti‑vibration pads further enhance noise efficiency.:contentReference[oaicite:3]{index=3}

SSO2 Bearing & Longevity

Equipped with Noctua’s second-generation SSO2 bearing and CNC‑milled brass shell, this fan achieves a Mean Time To Failure (MTTF) over 150,000 hours. Backed by Noctua’s 6‑year warranty, it ensures long-term reliability.:contentReference[oaicite:4]{index=4}
