More balance, more burst

Perfecting engineering

Introducing the Mobius 140 Black Edition, the latest addition to Cooler Master’s acclaimed Mobius case fan series. This version features all the high-performance elements of the classic Mobius, now in a sleek blackout design. With innovative ring blade design, loop dynamic bearing, oil reflow, anti-sway systems, and dust protection, the Mobius 140 Black Edition offers a stylish upgrade to a Cooler Master classic.

Ring blade design (RBD)

Interconnecting fan blades designed for a reinforced and rigid structure, eliminating vibration for stable and fluid fan operation.

Anti-vibration damper

Exclusive Cooler Master color accent dampers diminish vibration and rattling to maintain chassis stability for silent performance.

Pressure air acceleration

Angled inner frame rim with chamfered side vents boost airflow draw, maximizing force induced air pressure and diminishing dead air.

Loop dynamic bearing

New loop dynamic bearing design utilizes thick oil coating and lubrication to allow for stable performance.

Oil reflow system

Oil flows back to the sealed bearing to create constant lubrication against friction and increase the lifespan of the fan.

Dust proofing

A sealed, concave bearing prevents air and dust exposure and ensures a smooth transfer of motion.

Anti-sway system

Magnetic ring prevents bearing shaft from tilting, stabilizing the fan to prevent fan blade obstruction under various orientations, as well as oil spray.
