  • Includes anti-vibration mounts, extension cable and Y-cable for dual-fan PWM setups

Slim 120 mm Fan for Tight Builds

The Noctua NF-A12x15 PWM is a 120 x 15 mm case fan built for low-profile CPU coolers, HTPC enclosures and small-form-factor systems where a standard 25 mm fan cannot fit. Its 4-pin PWM connector allows automatic speed control through motherboard headers, while the included Low-Noise Adaptor caps the maximum speed at 1400 rpm for quieter operation.

PWM Control and Acoustic Limits

The fan spins up to 1850 rpm at full PWM duty and produces a maximum of 23.9 dB(A) at that speed. Using the supplied Low-Noise Adaptor reduces the top speed to 1400 rpm, lowering the acoustic ceiling further. The 4-pin interface provides automatic regulation but offers no manual voltage control on 3-pin headers.

Replaces Standard 25 mm Fans When Space Is Critical

This slim model fits where 120 x 25 mm fans are too thick, such as on slim tower coolers, radiators or cramped chassis. The jump is worthwhile only when physical clearance is the limiting factor; builds with room for a full-depth fan will gain more airflow from a standard 25 mm design.

Questions about this item

Should I pick the PWM version or a 3-pin model for my motherboard header?

The PWM 4-pin version lets your motherboard control speed automatically; with the supplied Low-Noise Adaptor the ceiling drops to 1400 RPM for quieter running.

What does the 23.9 dB(A) rating mean when the fan is inside my case?

At full 1850 RPM the fan reaches 23.9 dB(A); using the Low-Noise Adaptor limits it to 1400 RPM, so real-world noise will be lower in a closed chassis.

How does the 4-pin PWM interface limit the top speed in practice?

The 4-pin PWM header drives the fan up to 1850 RPM; fitting the included Low-Noise Adaptor caps PWM control at 1400 RPM for reduced noise.
