140 mm PWM case fan for quiet cooling

The Fractal Design Momentum 14 measures 140 mm by 25 mm and uses a 4-pin PWM connector for automatic speed control between 350 and 1800 RPM. It suits builders who want a single high-quality fan for intake or exhaust in a modern chassis. Buyers needing RGB illumination or a multi-fan kit should look elsewhere.

Straightforward mounting with vibration damping

Four integrated rubber bushings isolate the frame from the case to cut vibration noise. The daisy-chainable flat cable lets you link several fans on one header, reducing cable clutter. Ensure your motherboard header can supply enough current for the total fan count.

Steady airflow under continuous load

At full speed the fan delivers 79.79 CFM (135.6 m³/h) while the Fluid Dynamic Bearing and swept LCP blades keep noise to 31.9 dB(A). The wide PWM range including Zero RPM mode allows the fan to spin down completely during light loads, maintaining low acoustic output during long sessions.

Questions about this item

How can I confirm the fan is running at the correct 350 to 1800 RPM range after installation?

Use BIOS or fan-control software to read the 4-pin PWM signal; the fan should report speeds between 350 and 1800 RPM and drop to Zero RPM mode when the curve allows.

What comes in the box and which cables or brackets must be purchased separately?

The package includes one 140 mm black fan with integrated flat cable and rubber bushings; no extra mounting screws or ARGB controller are supplied.

Which version should I choose if I want the ARGB Gen 2 lighting ring?

Select the RGB version of the Momentum 14 series; the FD-F-MO1-1401 model listed here has no LED illumination.
