MFDB SilentFAN delivers quiet, reliable cooling with thoughtful design and clear performance benefits. - Silent operation and vibration damping: eight soft silicone pads at the four corners absorb vibrations at high speeds, keeping noise to a maximum of 25.5 dBA (sounds like rustling leaves). Ideal for work, gaming, or any time you want to minimize disturbance. - Hydraulic bearing longevity: uses ultra MFDB fluid dynamic bearing bearings with low friction coefficient magnetic levitation bearing technology, providing longer life than traditional bearings and a life expectancy of over 10,000 hours. - PWM and ARGB control: dynamically adjusts fan speed from 800 to 2500 rpm to reduce noise while maintaining cooling. PWM pin connects to SYS_FAN; motherboard synchronization uses the 5V D G pins for ARGB control. - 7 blades for strong airflow: seven high-pressure blades at up to 2500 RPM, delivering airflow up to 26.5 CFM with stable air pressure and robust cooling performance. Use scenarios: - Gaming PC or high-performance build requiring effective cooling with minimal noise during long sessions. - Professional workstation or content-creation rig needing stable temperatures and consistent ARGB lighting. - Small form factor or quiet desktop/builds where space, noise, and reliability are priorities.
