  • 4-pin interface supports speed monitoring and intelligent temperature control
  • CE certified with 54 dB noise level at full speed

High-speed 40 mm 12 V cooling fan

The Haywards DBTB0428B2G is a 40×40×28 mm DC fan that runs on 12 V and draws 1 A for 12 W. It targets builders who need maximum airflow from a compact frame and accept the resulting acoustic output.

18 000 RPM peak speed with PWM control

The motor spins up to 18 000 RPM ±10 % and is governed by a 4-wire PWM interface for intelligent temperature control. Speed measurement feedback lets the system monitor actual rotation in real time.

Double ball bearing rated for 70 000 hours

Two ball bearings support the rotor for a 70 000-hour service life. The fan operates between 7.0 V and 13.4 V and delivers 19.4 CFM at 54 dB, so it fits tight chassis spaces that can supply a 4-pin header and tolerate high-speed noise.

Questions about this item

How does 18000 RPM affect cooling in a real system?

The fan moves 19.4 CFM at up to 18000 RPM, giving strong airflow for small heatsinks, though the 54 dB noise level will be noticeable in quiet builds.

What does the 4-pin PWM interface control in practice?

The 4-wire PWM connection lets the motherboard vary speed between 7.0 V and 13.4 V, enabling automatic temperature-based regulation and rpm monitoring.

Will the 40×40×28 mm frame fit my existing mount?

The fan uses a standard 40 mm square footprint with 28 mm thickness; check that your bracket or case has matching screw holes and clearance for the deeper profile.
