Noctua NF-A6x25 FLX — 60 mm Premium Quiet Fan

60 × 25 mm3000 RPM19.3 dB(A)LNA + ULNA included

The Noctua NF-A6x25 FLX (part number NF-A6x25 FLX) is a 60 × 25 mm, 12 V 3-pin fan with 29.2 m³/h airflow at 3000 RPM and 19.3 dB(A), made for quiet upgrades in small cases, HTPCs, NAS enclosures, 3D printers and other devices with 60 mm fan slots. Two included adaptors let you drop to 2400 or 1600 RPM for even lower noise. Typically in stock with fast delivery across Cyprus.

Compatibility Note
12 V 3-pin fan with 50 mm hole spacing — check that your device uses a 60 × 60 × 25 mm fan and supplies 12 V. It can also be powered from a Molex 4-pin connector with the included 3:4-pin adaptor. 3-pin fans are controlled by voltage, not PWM.

Key Features

 
Three speed settings
Full speed 3000 RPM, 2400 RPM with the Low-Noise Adaptor and 1600 RPM (8.2 dB(A)) with the Ultra-Low-Noise Adaptor.
 
Flow acceleration channels
Suction-side channels speed up the air at the outer blade regions, lowering turbulence and improving efficiency.
 
SSO2 bearing, IP50
SSO2 bearing with over 150,000 hours MTTF plus IP50 dust protection, backed by a 6-year warranty.

Frequently Asked Questions

Can the NF-A6x25 FLX be powered without a fan header?
Yes. The included NA-AC1 adaptor connects it to a 4-pin Molex power connector from the PSU, running it at 12 V.
What do I need to know before buying the Noctua NF-A6x25 FLX?
It is a 12 V 3-pin fan without PWM; use the included adaptors to set a lower fixed speed. Check that your slot takes a 25 mm-thick 60 mm fan. Noctua fans ship with a 6-year manufacturer warranty.
Is the Noctua NF-A6x25 FLX 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
60 mm fans are often the loudest part of small devices, and the NF-A6x25 FLX with its two speed adaptors lets you balance cooling and silence without extra controllers. For PWM control choose the NF-A6x25 PWM version; for larger builds see our case fans.
