Compact 50 mm server fan
The SXDOOL efb0512ma is a 50 x 50 x 10 mm case fan built around a ball-bearing motor rated for 80000 hours of continuous operation. It connects through a standard three-pin header that reports speed to the motherboard. The unit targets builders who need a slim 12 V cooler for tight chassis, CPU heatsinks, power-supply retrofits or auxiliary water-cooling spots.
Steady-state thermal profile
At 4500 rpm the fan moves 9.21 cfm while producing 25 dBA, a level the supplier describes as ultra silent for sustained loads. The ball bearing maintains consistent airflow without the wear-in period or lubrication decay seen in sleeve designs, so output stays stable during long server or workstation sessions. No pulse-width modulation control is mentioned, so speed varies only with voltage.
Drop-in three-pin fitting
Installation uses the common three-pin mainboard interface; the third wire carries a tachometer signal for monitoring. Clearance is fixed at the 10 mm frame thickness, so the fan suits only locations that accept a 5010 form factor. Builders needing PWM control, larger frames or higher static pressure for dense radiators will need a different model.

Questions about this item
How loud is the 4500 rpm ball-bearing fan during continuous operation?
The fan runs at 25 dBA, which is quiet enough for server or workstation use even when spinning all day.
Does the 3-pin connector supply power and speed feedback to my motherboard?
Yes, the three-wire 3-pin plug delivers 12 V power and a tachometer signal so the board can monitor the 4500 rpm speed.
Will the 50 mm frame fit the same mounting holes as my existing 5010-size fans?
The 50 × 50 × 10 mm dimensions match the standard 5010 footprint, so it drops into the same screw pattern.
