The ultra-thin Cooler Master Mobius 120 Slim fan with a thickness of just 15 mm delivers powerful cooling to compact ITX and SFF builds. Thanks to the Ring Blade Design with interconnected blades, it minimizes vibrations and ensures smooth and stable operation. With speeds up to 2500 RPM, an airflow of 53.7 CFM, and a static pressure of 2.53 mmH2O, it handles higher loads, while the Loop Dynamic Bearing and 4-pin PWM control keep noise low and performance efficiently optimized.
The Cooler Master Mobius 120 Slim is a top-tier 120mm fan designed for spaces where every millimeter counts. Its 15 mm thickness allows installation in low-profile coolers, tight radiators, and SFF/ITX cases where standard 25 mm fans won’t fit. The innovative Ring Blade Design connects the blades into a rigid ring, reducing vibrations, increasing stability, and improving airflow direction.
With a maximum speed of 2500 RPM, airflow of 53.7 CFM, and static pressure of 2.53 mmH2O, it delivers excellent performance in case positions as well as on heatsinks and radiators. The three-phase motor and Loop Dynamic Bearing ensure quiet operation down to 31.4 dBA and a long service life of MTTF > 200,000 h. Precise PWM control allows the fan to respond dynamically to system temperatures, maintaining the ideal balance between noise and cooling.
- Ultra-thin 15 mm design – perfect compatibility for SFF/ITX and tight spaces.
- Ring Blade Design – higher stability, fewer vibrations, smoother airflow.
- High static pressure – ideal for filters, radiators, and dense grilles.
- 4-pin PWM – intelligent speed regulation and noise optimization.
- Reliable LDB bearing – long lifespan and low maintenance.
