More Balance, More Burst Perfecting Engineering Cooler Master’s Mobius140P ARGB is our new series of performance fans. With our enhanced Ring Blade Design, the Mobius Series optimizes both performance and acoustics, catering to a dynamic range of applications from case, liquid or air, to overclocking and intense gaming. Ring Blade Design (RBD) Interconnecting fan blades designed for a reinforced and rigid structure, eliminating vibration for stable and fluid fan operation. Oil Reflow Bearing System Our newly designed ORBS (Oil Reflow Bearing System)has thick oil film and lubrication formation that can achieve stable running Oil Reflow The oil flows back to the sealed bearing to create constant lubrication against friction and increases the life span of the fan. Dust Proofing The sealed and concave position of the 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. Pressure Air Acceleration Angled inner frame rim with chamfered side vents boost airflow draw, maximizing force induced air pressure and diminishing dead air. Absolute Acoustics Sound output fine tuned to the optimal prominence ratio to achieve sub 6dB noise levels without performance sacrifice. Anti-vibration Damper Exclusive Cooler Master color accent dampers diminish vibration and rattling to maintain chassis stability for silent performance. ARGB Motherboard Compatibility Addressable Gen 2 RGB syncs with Cooler Master’s MasterPlus+ software and dedicated controller, allowing customization of individual LED colors, effects, brightness and more – all from an intuitive, convenient interface.
