Compact 50 mm square fan

The OEM Industries FAL3F12LHSA is a 50 by 20 mm DC fan built for tight spaces such as projectors or small-form-factor systems. It runs on 12 V and draws 0.27 A through a standard three-pin connector. Ball-bearing construction supports continuous operation in confined enclosures.

12 V 0.27 A three-pin power

The single specification that decides fit is the 12 V 0.27 A three-pin interface; the cooler will only work where that exact voltage, current and header are available. Systems using two-pin, four-pin or 5 V headers cannot power this unit without an adapter. Builders needing PWM control or a different voltage must select another model.

No LED or bundled accessories

The package contains the fan only, with no LED lighting, mounting brackets, screws or software. Installers must supply their own fixation hardware and any required adapters. The bare-fan approach keeps cost low but adds assembly steps for the end user.

Questions about this item

What does the 0.27 A rating mean for a standard 12 V fan header?

At 12 V the fan draws 0.27 A, well within the typical 1 A limit of most motherboard headers.

What does the 3-pin connector provide compared with a 4-pin header?

The 3-pin plug supplies power and tachometer signal; speed is controlled by voltage rather than PWM.

Will the 50 mm by 20 mm frame fit my projector or small-form-factor build?

The square frame measures 50 mm on each side and is 20 mm thick, so verify your mounting holes and clearance against those dimensions.
