SKU CH-JF80-JEZMV MPN EFB0412VHD-R00Size

A 40 x 40 x 25 mm axial fan with double ball bearings runs on 12 V at 0.18 A for compact forced-air cooling

  • Double ball bearing ensures long service life
  • 12 V 0.18 A draws minimal power
  • 40 x 40 x 25 mm fits tight spaces
  • Axial design moves air efficiently
  • Original Delta build guarantees authenticity

Compact 40 mm axial fan

The DELTA EFB0412VHD-R00Size is a 40 x 40 x 25 mm axial case fan designed for tight spaces where efficient air exchange is required. It suits builders working on small-form-factor PCs, industrial enclosures or embedded systems that need reliable forced cooling without a large footprint. The double ball bearing supports continuous operation in hot or cold air flow paths.

12 V power and airflow ceiling

The fan runs on 12 V and draws 0.18 A, so the host system must supply that current on a standard 12 V rail. Airflow reaches up to 35 000 m³/h according to the manufacturer, representing the practical upper limit of this 4020-size axial design. Speed control is possible via analog or serial interface when the connected hardware supports it.

Verify mounting depth and connector

Before ordering, confirm that your chassis or device provides at least 25 mm of clearance for the fan frame and that the mounting holes match the 40 mm square pattern. Check that the power header can deliver 12 V at 0.18 A and that the connector type matches the fan lead. Ensure the intended airflow direction aligns with the heat-exchanger or component layout.

Questions about this item

Which 40 mm fan voltage and current rating should I pick for my build?

The EFB0412VHD-R00Size runs at 12 V and draws 0.18 A, so choose this version when your header supplies 12 V and can deliver at least 0.18 A.

What does the 35000 m3/h airflow figure mean once the fan is installed in a case?

The 35000 m3/h rating is a maximum free-air value; inside a case the actual airflow will be lower because of grilles, filters and component obstruction.

What connector standard does the 4020 fan use and what does it limit?

The 4020 axial fan uses a standard 3-pin header; speed is controlled by voltage, so the lowest speed is capped by the motherboard's minimum voltage output.
