Cooler Master Mobius 140 Black Edition Case Fan

Cooler Master Mobius 140 Black Edition Case Fan – Ring Blade Design (PWM), Ultra-Durable Loop Dynamic Bearing (max. 76.5 CFM, 2.3 mmH2O, 30 dBA), Chamfered Air-Focus Frame – Black
- HIGH-PRESSURE CASE FAN – The Mobius 140 Black Edition case fan is an excellent choice for extreme conditions such as ultra-compact (SFF) cases, overclocking, or high-intensity hardware usage (gaming, rendering and video editing)
- RING BLADE DESIGN – A revolutionary ring blade design employs connected fan blades with a more stable structure that reduces vibration & subsequent noise (30 dBA) – particularly during changes in fan speed (0-1900 RPM, 4-Pin PWM)
- LOOP DYNAMIC BEARING – An all-new loop dynamic bearing (LDB) utilises a thick oil coating & reflow system that generates cycled lubrication for incredible durability (160,000 hours MTTF) and employs a fully-sealed air & dust proof frame
- ANTI-SWAY SYSTEM – A magnetic ring keeps the bearing shaft from tilting which improves fan stability and prevents blade obstruction under various orientations
- ANGLED INNER FRAME – An angled inner frame with chamfered sides help focus & direct airflow for maximum pressure & efficiency (76.5 CFM, 2.3 mmH2O) which is integral to improving cooling performance
