40 mm ball-bearing case fan

The SunnyStar 405038-12HB is a 40 mm by 38 mm case fan that runs on 12 V and draws 0.75 A through a three-pin power connector. Ball bearings and a black non-LED frame are built for continuous airflow in tight chassis.

Server and compact-system builders

This fan suits servers or small-form-factor cases that accept a 40 mm mounting pattern and a three-pin header. Builders who need PWM speed control, larger diameters or RGB lighting should look at other models.

Three-pin 12 V power connector

The 3-pin header delivers fixed 12 V power without PWM signalling, so the fan runs at a constant speed unless the motherboard or controller supports voltage-based regulation.

أسئلة حول هذا المنتج

How do I install the 405038-12HB HAB fan in a 40 mm mounting hole, and which step is often missed?

Align the 40 mm square frame with the case holes, insert the four mounting screws through the fan corners, then connect the 3 pin power connector to the motherboard header — the step often missed is seating the connector fully so all three pins make contact.

What maintenance will the ball bearing in this 12 V .75 A fan need over time?

The ball bearing is sealed and does not require lubrication; if noise or vibration appears after extended use, replace the entire 405038-12HB HAB unit rather than attempting bearing service.

What is the first limit reached when this 40*38 mm fan runs continuously at 12 V?

Continuous operation at the rated 12 V and .75 A will eventually hit the ball bearing’s wear life, which typically becomes audible as increased noise before airflow drops below usable levels.
