Delta AFB1248EHE 120mm 48V Fan

The Delta AFB1248EHE is a 120mm DC brushless fan designed for 48V operation with a 0.74A current draw. It features a 4-wire PWM connector for speed control and dual ball bearings for durability. This component is intended for system integrators or technicians replacing a specific high-airflow cooler in compatible equipment.

Suited for 48V industrial or server slots

This fan suits maintenance teams servicing hardware that natively supplies 48V PWM power to a 12038 form-factor cooler. It is not for builders using standard desktop motherboards, which provide only 12V headers and cannot drive this unit. Buyers needing a 12V PWM fan or a lower-noise profile should look at alternative models.

48V 0.74A PWM power requirement

The single specification that decides fitment is the 48V 0.74A PWM electrical interface. Your target device must supply exactly this voltage and signalling on a 4-wire header; otherwise the fan will not spin or report speed. Verify the original part number AFB1248EHE against your service manual before purchasing.

Questions about this item

How much noise does the AFB1248EHE produce when running continuously at 4500-4999 rpm?

The fan is rated above 50 dBA at full speed, so expect noticeable airflow noise during sustained operation.

What power source and connector does the AFB1248EHE require to operate?

It needs a 48 V DC supply capable of 0.74 A and a standard 4-wire PWM header for speed control.

Will the 120 mm AFB1248EHE fit the same mounting holes as older 12038 coolers?

Yes, the 120 mm frame matches the 12038 footprint, so existing mounting points align directly.
