Noctua NF-A4x10 5V — 40 mm Premium Quiet 5 Volt Fan

5 V version4500 RPM17.9 dB(A)SSO2 · 6-year warranty

The Noctua NF-A4x10 5V (part number NF-A4x10 5V) is a 40 × 10 mm 3-pin fan that runs on 5 V at 4500 RPM and 17.9 dB(A), designed to replace noisy 5 V fans in network gear, storage devices, 3D printers and similar electronics. It is not intended for 12 V PC fan headers. Typically in stock with fast delivery across Cyprus.

Compatibility Note
5 V only (start 4 V, max 5.5 V) — do not connect to a standard 12 V PC fan header; for 12 V use the NF-A4x10 FLX. No USB power adaptor and no Low-Noise Adaptor are included. The OmniJoin set helps connect it to proprietary fan connectors; always check polarity and hole spacing (32 × 32 mm).

Key Features

 
Made for 5 V devices
Same 40 × 10 mm Noctua design as the 12 V model, but wound for 5 V so it delivers full performance in devices with 5 V fan supplies.
 
SSO2 bearing, IP50
Magnetically stabilised SSO2 bearing with over 150,000 hours MTTF and IP50 dust protection.
 
OmniJoin adaptor set
Lets you join the fan to the device's original proprietary connector, plus a 3:2-pin cable, 30 cm extension and anti-vibration mounts.

Frequently Asked Questions

Does the NF-A4x10 5V work on a PC motherboard fan header?
No. PC fan headers supply 12 V, which is too much for this 5 V fan. Noctua states it is not for use in PCs — choose the NF-A4x10 FLX for 12 V headers.
What do I need to know before buying the Noctua NF-A4x10 5V?
Confirm your device supplies 5 V and uses a 40 × 40 mm fan with 10 mm thickness. No USB adaptor is included. Noctua fans ship with a 6-year manufacturer warranty.
Is the Noctua NF-A4x10 5V quiet?
Yes. Noctua's SSO2-style magnetic bearing and optimised impeller keep noise low for the fan size, and all figures quoted here are Noctua's official measurements.
Singular Expert Insight
Many routers, NAS enclosures and 3D-printer hotends use 5 V 40 mm fans, and the NF-A4x10 5V is a direct, much quieter replacement. Double-check the voltage: the 12 V NF-A4x10 FLX looks identical. Browse more options in our case fans.

Buyer's Guide

Buy it if
Your device has a 5 V 40 mm fan you want to replace with a 17.9 dB(A) model.
Skip it if
You are connecting to a 12 V PC header — it is not designed for that.
