  • 12 V 0.55 A design fits standard headers
  • Compact 70 mm square frame suits tight spaces

70 mm 12 V centrifugal blower

The SXDOOL AB07012UX250301 is a 70 mm by 25 mm centrifugal blower that runs on 12 V and draws 0.55 A. It spins at 4200 rpm using a hydraulic maintenance-free bearing. The unit is designed as a direct replacement for the cooling assembly in the Sony VPL-DX122 projector.

Three-wire 3-pin connector with speed sense

The fan ships with a 12 cm lead terminated in a small three-pin plug carrying black, red and yellow conductors. The yellow wire provides a tachometer signal so the host system can monitor actual fan speed. No additional mounting hardware, adapters or software utilities are included in the package.

28 dBA at 4200 rpm for targeted spot cooling

At full speed the blower produces 28 dBA while moving air through a focused exhaust path, making it suitable for tight enclosures such as projector housings or small-form-factor chassis. The centrifugal design cannot deliver the high-volume throughput of an equivalent axial fan, so it is not suited for general case ventilation or high-heat-load components.

Questions about this item

How often does the hydraulic bearing need service or replacement?

The hydraulic bearing is maintenance-free, so no routine service or replacement is required.

What limits continuous operation at 4200 rpm?

The 12 V, 0.55 A rating and 28 dBA noise level define the thermal and acoustic ceiling during sustained use.

How much noise and heat does it produce running all day?

It runs at 28 dBA and draws 0.55 A at 12 V, so acoustic output and power draw stay constant during extended operation.
