120 mm PWM case fan for quiet builds

The Fractal Design FD-F-MO1-1201 is a single 120 mm case fan built for systems that prioritise low noise. It targets builders who want reliable airflow without audible distraction. Buyers needing addressable RGB lighting or higher static pressure for dense radiators should look elsewhere.

Practical limits of 4-pin PWM control

The fan spins between 350 and 2200 RPM via a standard 4-pin PWM header, delivering up to 67.34 CFM at 31.3 dB(A). Zero RPM mode lets the fan stop completely at low loads. Motherboards without PWM headers cannot regulate speed automatically.

LCP blades, FDB and daisy-chain cable

Blades use Liquid Crystal Polymer for stiffness and a swept profile that reduces turbulence. A true Fluid Dynamic Bearing with herringbone structure ensures smooth, long-life operation. Integrated rubber bushings dampen vibration transfer to the chassis. Daisy-chainable flat cables simplify routing multiple fans in series.

Questions about this item

Is this the only size available in the Momentum series?

This model is a single 120 mm fan with a 25 mm thickness; other sizes are separate SKUs.

What does the 67.34 CFM airflow figure mean when the fan is installed in a case?

At 2200 RPM it moves up to 67.34 CFM (114.6 m³/h) through an open grille; actual flow drops with filters, grilles or radiator resistance.

Does the 4-pin PWM connector allow zero-RPM mode and daisy-chaining?

Yes, the 4-pin PWM header supports 350–2200 RPM control including Zero RPM mode, and the integrated flat cable lets you daisy-chain multiple fans.
