Cooler Master Mobius 140 Black Edition PWM Fan, Fluid Dynamic Bearing, 140mm, Black

This is a 140mm cooling fan specifically engineered for efficient air movement within a standard PC case chassis. The unit utilizes nine precision-shaped blades to maximize air displacement, ensuring effective heat dissipation from internal components. It operates across a controllable rotational range, achieving a maximum speed of 2000 RPM and delivering a substantial airflow output of 76.5 CFM. The operational design maintains stable thermal performance under demanding system conditions.

Speed regulation is managed through standard PWM connectivity, allowing for dynamic adjustment based on real-time system temperature requirements, including the ability to stop rotation completely when cooling is unnecessary. At peak speed, the fan generates a measured noise level of 29.9 dB. The fan incorporates a Fluid Dynamic Bearing (FDB) mechanism, a design choice intended to minimize rotational friction, thereby contributing to quiet operation and an extended operational lifespan. This unit carries a rated Mean Time Between Failures (MTBF) of 100,000 hours.
