Upgrade Your Compact Device Cooling
The Noctua NF-A4x10 PWM fan is engineered for superior quiet cooling in compact applications. Its advanced aerodynamic design, featuring Flow Acceleration Channels and the Noctua AAO frame, optimizes airflow while minimizing noise. This 40x40x10mm fan is perfect for upgrading cooling in 1U servers, network equipment, storage devices, and other electronics where space is limited but performance is critical. The included Low-Noise Adaptor further reduces speed to 3700 RPM for exceptionally quiet operation.
This 4-pin PWM version allows for automatic speed control, adapting its performance to your system's needs. The broad speed range of 1000-5000 RPM (or 3700 RPM with the LNA) ensures efficient cooling under load and near-silent operation at idle. Built with a premium SSO2 bearing, this fan boasts an impressive MTTF of over 150,000 hours, guaranteeing long-term reliability and smooth operation. The fan's beige and brown color scheme is a signature Noctua aesthetic.
While local alternatives may offer basic cooling, the Noctua NF-A4x10 PWM provides a scientifically optimized solution for demanding environments. All customs duties and GST are included in the price, with delivery via ExpressBox tracked service. 16-18 days for your order.
Engineered for Peak Performance in Demanding Environments
The Noctua NF-A4x10 PWM fan utilizes advanced aerodynamic principles, including Flow Acceleration Channels and the Advanced Acoustic Optimisation (AAO) frame. This design ensures maximum airflow with minimal noise, crucial for sensitive electronics. Unlike generic fans, its construction is built for sustained operation, boasting a >150,000 hour MTTF. This fan is imported from authorized US retailers, ensuring you receive an authentic product with superior engineering for your critical equipment.
Ideal for Compact Systems, Not for General Air Cooling
This fan is perfect for small form-factor devices like 1U servers, network switches, NAS, and DVRs where standard larger fans won't fit. It's designed for targeted airflow in confined spaces. However, it is not suitable for large PC cases or high-TDP CPUs that require larger heatsinks and higher airflow fans (e.g., 120mm or 140mm). If you need general PC case cooling, consider Noctua's larger fan models.
Typical situations where Noctua NF-A4x10 PWM Fan 40x40x10mm | High-Performance Quiet Cooling 5000 RPM 4-Pin PWM helps — illustrative scenarios, not customer reviews.
A user needs to cool a compact 1U server rack in an office environment in Mumbai.
The Noctua NF-A4x10 PWM fan's 40x10mm size fits perfectly in tight server chassis. Its quiet operation (max 19.6 dB(A)) ensures minimal disruption in an office setting, while the 5000 RPM PWM control provides effective cooling under load.
A home user wants to upgrade a noisy fan in their network router or NAS device.
This fan's award-winning design and SSO2 bearing offer superior quietness and reliability. The included Low-Noise Adaptor caps speed at 3700 RPM for near-silent operation, ideal for home use where fan noise is a concern.

| Feature | Noctua NF-A4x10 PWM | Others |
|---|---|---|
| Cooling Performance | Optimized airflow with Flow Acceleration Channels and AAO frame for superior quiet cooling. | Generic fans may offer basic airflow but lack advanced aerodynamic design for optimal quiet performance. |
| Speed Control | 4-pin PWM for automatic speed adjustment (1000-5000 RPM) + LNA for 3700 RPM max. | Many local fans use 3-pin connectors for fixed voltage speed, lacking dynamic temperature-based control. |
| Noise Level | Max 19.6 dB(A) at 5000 RPM; significantly quieter with LNA. | Local fans often exceed 25-30 dB(A) even at lower speeds, leading to noticeable operational noise. |
| Durability & Lifespan | Premium SSO2 bearing with >150,000 hours MTTF. | Standard sleeve or ball bearings typically offer <50,000 hours MTTF, requiring more frequent replacement. |
| Compact Size Suitability | 40x40x10mm ideal for 1U servers, NAS, routers. | Local options in this size are rare; larger fans are not suitable for confined spaces. |
