Four 120 mm sleeve-bearing fans move 44.73 CFM at 19.1 dBA with 3-pin connectors
This kit contains four 120mm case fans designed for quiet system cooling. Each unit spins at 1200 RPM to deliver 44.73 CFM of airflow while producing only 19.1 dBA of noise. The sleeve bearing is rated for 30000 hours of operation. Power is supplied through a standard 3-pin connector at 12VDC.
Builders seeking a silent, low-cost way to populate multiple case mounts will appreciate the ultra-low acoustic profile. The fixed 1200 RPM speed suits constant-airflow configurations without software tuning. Systems requiring PWM speed curves, higher static pressure for dense radiators, or addressable lighting should consider alternative models.
The single specification that decides suitability is the non-adjustable 1200 RPM operating point. It locks both the 44.73 CFM airflow and the 19.1 dBA noise floor, so the fans cannot be slowed for quieter idling or sped up for heavier loads. Verify that your motherboard headers and thermal targets match this constant output before purchasing.

Each fan uses a sleeve bearing rated for 30,000 hours of continuous operation, so the four-pack should run for years under normal daily use before any bearing service is required.
The 3-pin connectors lock every fan to a fixed 12 V supply, capping speed at 1200 RPM ±10 % and airflow at 44.73 CFM per fan with no PWM headroom for extra demand.
Total power draw is 1.8 W per fan at 12 V and 0.15 A, while each unit emits 19.1 dBA, so the combined thermal load stays low and the acoustic profile remains barely audible in a typical case.
