SXDOOL AD1212HB-A71GL 12025 12V .37A 2200 RPM 87.870 CFM 38 dBA 3-pin 2-ball case fan

120 mm double-ball-bearing case fan

The ADDA AD1212HB-A71GL is a 120 mm case fan built around a dual ball-bearing motor rated for 180 000 hours of continuous operation. It runs at 2 200 RPM from a 12 V supply drawing 0.37 A and connects via a standard three-pin header that reports speed to the motherboard. No LED lighting is fitted. The black frame measures 120 mm by 120 mm by 25 mm.

Builders who need measured airflow

This fan suits system integrators and enthusiasts who want a reliable high-static-pressure cooler for dense heatsinks or restricted intake paths. The dual ball bearings and published 180 000-hour MTBF target continuous-duty servers or workstations. Buyers who require PWM speed control, addressable lighting or noise levels below 35 dBA should look elsewhere.

87.87 CFM at 38 dBA with three-pin speed reporting

The combination of 87.87 CFM airflow and 38 dBA acoustic output at 2 200 RPM is the single figure that determines fit. If your thermal design demands that specific air-volume-to-noise ratio and a three-pin tachometer signal, the AD1212HB-A71GL matches the requirement; otherwise a different airflow or connector type is needed.
