Fans FFB1424UHE Delta 14038 24V 4.02A 14cm Case Fan

SKU CH-Q391-F2YWH

A 24 V DC axial fan moves 367.6 CFM at 5500 RPM with 1.644 inH₂O static pressure

  • High airflow of 367.6 CFM for demanding cooling
  • 24 V DC operation at 4.02 A for stable power delivery
  • Ball bearing rated for long service life
  • Certified to CE, CSA, UL and VDE standards
  • Wide operating range from -10 °C to 70 °C

High-Airflow 24 V Axial Fan

This Delta FFB1424UHE moves 367.6 CFM at 5500 RPM with 1.644 inches of water static pressure. The 139.7 mm square frame is 38 mm deep and draws 80.4 W from a 24 V DC supply. Ball bearings and a tube-shaft design support continuous operation from -10 to 70 °C.

Industrial and Server Cooling Builds

Engineers specifying CE, CSA, UL and VDE approved forced-air cooling for rack equipment, telecom enclosures or medical rail systems will match the 4.02 A current draw and 74 dB(A) noise level. Buyers who need PWM speed control, a standard 4-pin motherboard connector or quieter sub-50 dB operation should look at other products.

24 V DC Voltage Rating

The fan requires a 24 V DC power source capable of delivering at least 4.02 A. Supplying a different voltage will prevent the unit from reaching its rated 5500 RPM and 367.6 CFM performance.

Questions about this item

How do I decide between the 24 V version and other voltage options for the FFB1424UHE?

This model is rated for 24 VDC only and draws 4.02 A at full speed, so it must be connected to a 24 V supply capable of at least 80.4 W.

What does the 367.6 CFM airflow figure mean when the fan is mounted in a case?

At 5500 RPM the fan moves 367.6 CFM (10.41 m³/min) of free air; inside a chassis the actual flow will be lower once filters, grilles and component obstructions add resistance.

How does the 2-lead termination affect speed control and monitoring?

The two-wire lead provides power only, so the fan runs at a constant 5500 RPM whenever 24 V is applied; PWM control or tachometer feedback requires a 3- or 4-wire version.
