Noctua NF-A12x25 ULN Ultra-Low-Noise 120mm

120 mm · 1200 RPM12.1 dB(A)32.8 CFM3-pin · 6-year warranty

The Noctua NF-A12x25 ULN (part number NF-A12X25 ULN) is an ultra-low-noise 120 mm fan that runs at 1200 RPM and only 12.1 dB(A), aimed at silent PCs, home-theatre systems and recording studios where acoustics come first. It uses the same Sterrox LCP impeller and SSO2 bearing as Noctua’s flagship NF-A12x25, tuned for whisper-quiet operation.

Typically in stock with fast delivery across Cyprus.

Compatibility note: This is a 3-pin fan (no PWM). Speed control needs a fan header in DC/voltage mode — on a PWM-only header it runs at full 1200 RPM. The included 3-to-4-pin adaptor also allows connection to a PSU Molex-type lead at fixed speed. Its low airflow (32.8 CFM) suits silent systems, not high-heat gaming rigs.
Best For
✓ Silent and fanless-style PCs
✓ Home-theatre PCs
✓ Recording studios
✓ Low-power office systems
✓ Bedroom PCs
✓ Quiet NAS or file servers

Frequently Asked Questions

Is the Noctua NF-A12x25 ULN quiet enough for a silent PC?
Yes. It produces only 12.1 dB(A) at its maximum 1200 RPM and 7.6 dB(A) with the included Low-Noise Adaptor.
Does the NF-A12x25 ULN support PWM control?
No. It is a 3-pin fan controlled by voltage. Set your motherboard header to DC mode; for PWM control choose the NF-A12x25 PWM.
What is the difference between the NF-A12x25 ULN and the NF-A12x25 PWM?
The ULN version tops out at 1200 RPM and 32.8 CFM for maximum silence, while the NF-A12x25 PWM reaches 2000 RPM, 60.1 CFM and 2.34 mmH2O with PWM control.
Is the NF-A12x25 ULN suitable for a gaming PC?
Only for low-heat builds. Its 32.8 CFM is designed for silence; for gaming or radiators the NF-A12x25 PWM gives much more airflow and pressure.
Singular Expert Insight
The ULN version is for builders who value silence above all — HTPCs, studio machines and low-power systems. If your system runs hot or uses a radiator, the standard NF-A12x25 PWM offers far more headroom with PWM control. See all case fans.

Buyer's Guide

Buy it if
You want a near-silent 120 mm fan (12.1 dB(A)) for an HTPC, studio or low-power PC.
Skip it if
You need PWM control or high airflow for a gaming PC or radiator.
Also consider
Noctua NF-A12x25 PWM for more airflow, or NF-A12x25 PWM chromax.black.swap in black.
