Compact server fan for high-density chassis
The DBTA0328B2G is a 38 mm square centrifugal fan rated at 22000 RPM and 25 CFM airflow. It targets builders fitting medical, rail, industrial or new-energy vehicle enclosures where space is 3.8 cm tall and a 12 V PWM signal is available. Ball-bearing construction and a 50000-hour life rating at 40 °C support continuous duty in demanding environments.
Verify voltage range and connector before ordering
Your system must supply 10.8 V to 13.2 V DC and accept a four-lead PWM connector with tachometer feedback. The fan draws 0.55 A at 12 V (1.15 A start-up), so the header or fan controller must handle that current. Mounting holes suit a 38 mm square footprint; ensure 28 mm depth clearance inside the chassis.
Expect 60 dB(A) at full speed under load
At 22000 RPM the unit produces 60 dB(A), typical for high-volume server cooling in the 14 °F to 140 °F operating window. PWM control lets the motherboard reduce speed and noise when thermal headroom exists. Rated power is modest at 12 V × 0.55 A, and the 48 g weight adds minimal stress to dense assemblies.

Questions about this item
Does the DBTA0328B2G ship with mounting screws or a PWM cable, or must I buy them separately?
The unit is supplied as the fan only; mounting hardware and any extension cables are not included and must be sourced separately.
How do I choose between the 12 V 0.55 A and 1.15 A current ratings for this 38 mm fan?
The nameplate lists 0.55 A rated current with a 10.8–13.2 VDC range; the 1.15 A figure appears in the supplier title only. Use the 0.55 A value for power-budget planning.
What does 22000 RPM and 60 dB(A) mean for airflow inside a typical server chassis?
At 22000 RPM the fan moves 25 CFM (0.573 m³/min) through its 38 × 38 × 28 mm frame; expect audible 60 dB(A) noise, suited for high-density rack or industrial cooling rather than quiet desktop use.
