High-Speed 40 mm Cooling Fan

The Haywards DBTB0428B2G is a 40×40×28 mm axial fan that spins at up to 18000 RPM. It delivers 19.4 CFM of airflow for industrial control machines or compact computer cases that need concentrated cooling in a tight space.

4-Pin PWM Integration

A 4-wire 12 V interface accepts PWM intelligent temperature control and returns a speed-measurement signal to the host system. The fan operates between 7.0 and 13.4 V and draws 0.17 A, so it connects directly to standard 4-pin headers without extra cabling.

Double Ball Bearing Longevity

Two ball bearings are rated for 70000 hours of continuous running, reducing the chance of premature wear in high-RPM use. The plastic frame keeps weight low while the 54 dB noise level at full speed signals that this unit suits environments where airflow takes priority over silence.

Questions about this item

What is the maximum current draw this 12 V fan can reach under sustained load?

The fan is rated at 1 A current with a 12 W power rating, and the operating voltage range is 7.0-13.4 V.

How loud is the fan at its top speed of 18000 RPM during all-day operation?

The radiator noise is specified as 54 dB at full speed, and the supplier notes the high speed produces noticeable noise.

Does this 4-pin PWM fan need a motherboard header that supplies 12 V and a PWM signal?

Yes, it uses a 4-wire interface for PWM intelligent temperature control and speed measurement, requiring a standard 12 V 4-pin header.
