  • High airflow cooling from 48V 1.3A operation
  • PWM intelligent speed control adjusts fan speed automatically

48 V 120 mm server fan

The AVC 2B12038B48U is a 120 × 120 × 38 mm DC fan built for 48 V server and workstation chassis. It targets integrators who need high airflow in rack-mount or water-cooled systems.

4-pin PWM speed control

A four-pin interface provides speed measurement and intelligent PWM adjustment so the fan ramps only when thermal load demands it. The double ball bearing is rated for 10.0000 hours at 25 °C and 45–85 % relative humidity.

1.3 A high air-volume output

At 48 V and 1.3 A the fan delivers strong static pressure for radiator stacks and dense server enclosures. It suits CPU radiator, power-supply retrofit and game-console cooling but lacks the lower-voltage rails required for standard desktop motherboards.

Questions about this item

What does 1.3 A at 48 V mean for power draw in my server?

The fan draws 1.3 A from a 48 V rail, so plan for that current on your power distribution.

What does the 4-pin interface actually control?

The 4-pin connector carries PWM speed control and a tachometer signal for monitoring.

Will the 120 × 120 × 38 mm frame fit my 120 mm mount?

Yes, the 120 mm square footprint matches standard 120 mm mounting holes; allow 38 mm depth clearance.
