Fans 414JHH 40x40mm 24V 3.6W 13000rpm Ball Bearing Case Fan

SKU CH-R85Z-WJPQ2

A 40 mm square DC axial fan that moves 24 m³/h at 13 000 rpm with ball bearings for any-orientation mounting

  • 24 V DC supply simplifies integration into 24 V systems
  • 13 000 rpm delivers 24 m³/h airflow for dense thermal loads
  • Ball bearings allow mounting in any orientation without wear
  • Aerodynamically shaped housing reduces turbulence to 46 dB noise
  • 6 W draw at 150 mA keeps power budgets low

40×40 mm 24 V ball-bearing case fan

This 40×40 mm axial fan runs on 24 V dc and draws 3.6 W at 13000 rpm. Ball bearings allow installation in any orientation while delivering 24 m³/h of airflow at 46 dB noise level. It suits compact thermal-management tasks in dense electronic enclosures.

Replaces 40 mm fans rated below 13000 rpm

The 400 series design moves more air through the same 25.4 mm depth than slower 40 mm units. Upgrading is worthwhile when the existing fan cannot meet the thermal load or when a 3-wire speed signal is required for monitoring.

Fits tight 40 mm mounting grids needing high

Builders who need larger airflow volumes or quieter operation at lower speeds should consider bigger frame sizes. The 150 mA current draw also limits use on headers rated for less than 24 V dc.

Questions about this item

Will the 40 mm square frame and 25.4 mm depth fit my 40 mm mounting holes?

The fan measures 40 mm by 40 mm with a 25.4 mm depth, matching standard 40 mm mounting patterns.

How do I connect the three wires to a 24 V supply?

Connect the red wire to 24 V dc, the black wire to ground, and the third wire to the speed-sense header; the fan draws up to 150 mA.

When should I expect to replace the ball bearings?

Ball bearings in the 400 series are rated for long life; replace the fan if noise rises above 46 dB or airflow drops below 24 m3/h.
