Cooler Master Mobius 120 Computer case Fan 12 cm Black

HIGH-PRESSURE CASE FAN - The Mobius 120 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 (22.6 dBA) - particularly during changes in fan speed (0-2050 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 (200,000 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 (63.1 CFM, 2.69 mmH2O) which is integral to improving cooling performance
