  • Three-wire connection enables speed monitoring
  • 15 mm slim profile suits low-profile builds

Compact 40 mm 12 V case fan

The Delta AFB0412HHB measures 40 by 40 by 15 mm and runs on a 12 V supply drawing 0.20 A. Its three-wire connection provides speed feedback for motherboard monitoring. Ball-bearing construction targets long service life in tight chassis spaces where larger fans cannot fit.

Sustained-load behaviour

Ball bearings maintain consistent rotational speed during continuous operation without the friction increase seen in sleeve designs. The 0.20 A draw remains stable over extended periods, delivering steady airflow for component cooling. Builders needing higher static pressure or larger frame sizes should consider alternative models.

Questions about this item

How much heat and noise does the AFB0412HHB generate when running continuously?

The fan draws 0.20 A at 12 V and uses a ball bearing, so it runs steadily with minimal friction heat and consistent acoustic output.

What connector or header must my motherboard or controller provide for this fan?

It has a three-wire lead that plugs into a standard 3-pin or 4-pin 12 V fan header on the board.
