Noctua NF-A12x25PWM Quiet 120mm Low Noise Fan

Description

Product Overview

The Noctua NF-A12x25PWM is a 120 × 120 × 25 mm premium case fan designed for enthusiasts who demand both high airflow and whisper‑quiet operation. Constructed from Sterrox LCP material, the fan blades achieve a record‑tight 0.5 mm tip clearance, while the AAO frame and Flow Acceleration Channels maximize static pressure. Operating at 12 V with a 4‑pin PWM connector, it reaches up to 2000 RPM (1700 RPM with the low‑noise adaptor) and produces only 22.6 dB(A) of sound. With an airflow capacity of 102.1 m³/h and a maximum rotational speed of 2000 RPM, it is suitable for case ventilation, CPU coolers, water‑cooling radiators, and AIO systems.

Usage

Designed for desktop PCs, the NF‑A12x25PWM excels in high‑performance builds where cooling efficiency and acoustic comfort are critical. Install it on front, top, or rear case panels, or mount it on radiators for liquid‑cooling loops. Its PWM control allows automatic speed adjustment based on temperature, ensuring optimal cooling under load while staying silent during idle periods.

FAQ

What size is the fan and will it fit standard case mounts?

The NF‑A12x25PWM measures 120 mm × 120 mm × 25 mm and uses the standard 4‑pin PWM connector, making it compatible with all typical case fan mounts.

Can I run two fans on a single PWM header?

Yes, the included Y‑cable allows you to connect two NF‑A12x25PWM fans to one PWM header, enabling synchronized speed control.

Is the fan suitable for radiator cooling?

Absolutely. Its high static pressure and airflow make it ideal for both air‑to‑air and liquid‑cooling radiators.

How does the low‑noise adaptor affect performance?

The adaptor limits the maximum speed to 1700 RPM, reducing noise to around 19 dB(A) while still providing ample airflow for most cooling scenarios.

What warranty does Noctua offer?

Noctua provides a six‑year warranty on the NF‑A12x25PWM, reflecting confidence in its durability and build quality.
