30 mm axial fan for tight spaces

The NMB Technologies 1204KL-04W-B59 is a new 12 V DC axial fan measuring 30 mm square and 10 mm thick. It delivers 3.8 CFM of airflow at 10500 RPM while drawing 0.96 W. A ball bearing and locking rotor sensor support reliable operation in medical, rail, industrial and embedded equipment.

Suits builds needing a 30x10 mm 12 V fan

This unit fits designs that specify a 30 mm square frame with a 10 mm depth and a three-lead connection. Buyers who need a larger frame, higher static pressure, lower acoustic output or a different voltage should look at other models. The locked-rotor signal is useful for health monitoring but adds a wire.

3.8 CFM airflow at 10500 RPM

The single figure that decides fit is the rated airflow of 3.8 CFM produced at 10500 RPM with a static pressure of 0.216 inch water column. If the thermal design requires more airflow or higher pressure than this rating, the fan will not meet the cooling target.

Highlights

  • 8 CFM airflow cools tight spaces
  • 10500 RPM delivers targeted cooling performance
  • 27 dB noise keeps operation quiet
  • Ball bearing ensures long service life
  • Locked rotor sensor protects against failure

Questions about this item

What comes with the 1204KL-04W-B59 fan and do I need a separate connector?

The fan has three leads for power and the locking-rotor sensor; no extra connector is included so you will need a matching 3-pin header or adapter.

The spec sheet lists 27 dB and 34 dB noise figures — which one should I expect?

27 dB is the manufacturer's rated noise; 34 dB appears in the broader application notes, so plan for the lower value in a typical build.

What does the 3.8 CFM airflow mean for cooling a small enclosure?

At 10 500 RPM the fan moves 3.8 CFM with 0.216 inch water column static pressure, suited for tight spaces like 30 mm square cavities.
