OEM Industries AFB1248HF-R00 48V Fan

This 120mm cooling fan operates on 48V DC with a 0.17A draw. It uses a three-wire power connector and a dual ball bearing. The frame measures 120 by 120 by 32mm and includes a stop-turn alarm function. No LED lighting is fitted.

Suited for 48V industrial or server chassis

The fan fits systems that supply 48V directly to a three-pin header and require a stall alarm signal. Builds that run on 12V or 24V rails cannot use this unit without a separate voltage converter. Buyers needing PWM speed control or standard four-pin motherboard headers should look at other models.

Critical spec is the 48V three-wire interface

The power connector and voltage rating are fixed; they must match the host equipment exactly. A mismatched rail will prevent operation or damage the motor. Verify the header pinout and supply voltage before purchase.

Questions about this item

How loud is the AFB1248HF 120 mm 48 V fan when running continuously?

The supplier data does not publish an acoustic rating for this model.

What connector or voltage source does the 3-wire 48 V AFB1248HF need to operate?

It requires a 48 V DC supply with a 3-pin header that matches the fan’s power, ground and tachometer pins.

Will this 120 mm 48 V ball-bearing fan fit the mounting holes on an older 120 mm chassis bracket?

Yes, the 120 × 120 × 32 mm frame uses the standard 120 mm hole pattern, so it aligns with existing brackets.
