SXDOOL AD1212LB-A71GL 120mm Case Fan
The SXDOOL AD1212LB-A71GL is a 120mm case fan built around a double ball bearing rated for 50000 hours of operation. It targets system builders who need reliable airflow for server chassis, water-cooling radiators or power-supply fan replacements. The 2-pin power connector supplies DC12V at 0.24 A without PWM speed control.
Installing the 2-pin fan in standard 120mm
The fan fits 120mm mounting holes using four screws and draws power from a 2-pin header on the motherboard or a Molex adapter. Because the connector lacks a tachometer wire, the system cannot report RPM or trigger fan-failure alarms. Installers should verify that the header remains powered at the desired voltage; some boards only supply variable voltage on 4-pin headers.
Sustained-load behaviour of the double ball bearing
At 2050 RPM the fan moves 80.50 CFM while producing 38 dB(A), figures that remain stable during continuous duty. The double ball bearing maintains consistent speed and noise over long periods without the lubrication decay seen in sleeve designs. Buyers who require PWM speed curves or software monitoring should choose a 3-pin or 4-pin model instead.

Questions about this item
How do I verify the fan is running at the rated 2050 RPM after installation?
Use motherboard BIOS or a monitoring utility to read the tach signal from the 2-pin header; it should report 2050 RPM ±10% when the fan receives 12 V.
What comes in the box and what must I supply?
The package contains the 120×120×25 mm ADDA AD1212LB-A71GL fan only; you must provide a 2-pin 12 V power source and mounting screws.
Which airflow and noise combination should I pick for a quiet server build?
This single model delivers 80.5 CFM at 38 dB(A) with a double-ball bearing rated for 50 000 hours, matching the stated quiet-server target.
