Fractal Design Momentum 14 PWM Fan, Fluid Dynamic Bearing, 140mm, Black

This 140mm cooling fan is engineered for effective heat dissipation within PC case environments. It is designed to deliver a balance of high airflow and static pressure required for modern system components. The unit operates across a wide speed range, from a minimum of 350 RPM up to a maximum rotational speed of 1800 RPM, controlled precisely via a 4-pin PWM interface. At peak speed, the fan generates an airflow rating of 79.79 CFM and achieves a static pressure of 2.26 mmH₂O.

Longevity is addressed by the integrated Fluid Dynamic Bearing (FDB) system, which promotes prolonged operational stability and reduces mechanical friction. This bearing technology contributes to a Mean Time To Failure (MTTF) rating of 90,000 hours. The fan exhibits a maximum acoustic output of 31.9 dB when running at its highest speed setting. Power specifications include a rating of 2.16 W power consumption running on a standard 12V input, connected via a 0.5-meter cable. The blades are constructed from Liquid Crystal Polymer (LCP) to maintain structural integrity and minimize vibration.
