Fan Cooler Master Mobius 120 Black Edition 12 cm 107.1 m³/h

The Cooler Master Mobius 120 Black Edition is a 120 mm case fan engineered for efficient airflow in computer chassis. The blackout design keeps visual impact minimal while maintaining the Mobius series' structural ring blade, Loop Dynamic Bearing (LDB) and additional protections that extend life and stabilize operation. With an airflow rating of 107.1 m³/h (63.1 CFM) and support for PWM control, this fan is intended for intake or general case ventilation.

Advantages

The ring blade construction maintains a rigid fan frame to reduce deformation and increase effective airflow. Loop Dynamic Bearing with oil reflow returns lubricant to the sealed bearing for continuous lubrication and longer service life. A sealed, concave bearing position and dust protection reduce particulate ingress, while an anti-sway magnetic ring stabilizes the shaft to prevent tilt and minimize blade obstruction across orientations.

Suitable for

• Case ventilation and intake airflow
• General desktop PC cooling
• Systems requiring quiet, durable fans with PWM control

How to use

Install the Mobius 120 Black Edition in a compatible 120 mm fan slot in the computer case, aligning airflow direction as required for intake or exhaust. Connect the fan to a PWM-capable header on the motherboard or to a compatible fan controller to enable speed control. Secure with the provided screws or mounting hardware, ensure clearances around the fan blades, and verify cable routing to avoid contact with the blades.

Recommendations

For optimal performance, use the fan as part of a coordinated case airflow plan: position as an intake to improve front-to-back airflow or as an exhaust to assist hot-air removal. Periodically check and clean dust from the fan and filter areas to maintain airflow and prolong bearing life.
