MFDB Silent Fan 72mm PWM ARGB Case Fan Silent operation and vibration control The MFDB fan uses eight soft silicone pads at the four corners to absorb vibrations at speeds. Maximum noise is 25.5 dBA, roughly the sound of falling leaves, helping minimize disturbance during work or gaming. Easy installation and compatibility Compatible with all chassis types and designed for easy mounting. Standard power interface design and 72 mm hole spacing (distance between the centers of the two screw holes) for straightforward installation. PWM and ARGB control Dynamic speed control from 800 to 2500 RPM to reduce noise while maintaining cooling performance. PWM can be connected to the SYS_FAN header, with ARGB synchronization via the motherboard using the 5V D G pins. performance blade design Seven pressure blades run up to 2500 RPM with airflow up to 26.5 CFM, delivering stable air pressure and strong airflow to improve cooling performance. Use scenarios Gaming PC: Quiet operation during long sessions with reliable cooling for GPUs and CPUs. Workstation or content creation PC: Lownoise cooling during rendering and heavy workloads. Small form factor or case with RGB lighting: ARGB support adds visual without compromising airflow.
