Delta EFB0412VHD-F00
Delta 40 × 40 × 20 mm axial frame server/equipment axial fan. Identify by the complete model and suffix on the label; related series members may differ in depth, lead count, speed, controls and load.
IDENTIFICATION: Match the complete printed model and suffix to the physical part. These records describe individual Delta SKUs, not interchangeable series families.
Specifications
| Catalog subcategory | Server fans and blowers |
|---|---|
| Exact model | Delta EFB0412VHD-F00 |
| Frame | 40 × 40 × 20 mm axial frame |
| Electrical rating | 12 V DC; 0.12 A; 1.44 W |

| Airflow / static pressure | No text-verifiable airflow/static-pressure number is reproduced; use the exact model datasheet curve. |
| Connector and signal | Four lead wires; manufacturer listing specifies tachometer sensing. The control protocol and pin order must be confirmed from the exact drawing/host harness. |
Server and system compatibility cautions
This is a miniature 40 mm fan, not a standard 40 × 28 mm server fan. Verify the mounting depth, connector, tach interpretation and clearance; do not assume a PC four-pin PWM pinout.
- Disconnect power before service; retain the system’s guards and airflow direction, and keep cables clear of the impeller.
- Never infer pinout, control protocol, startup current or fan-failure reporting from wire color or a similar model. Follow the host service manual and the exact Delta drawing.
- After replacement, verify tach/fan-failure monitoring and cooling under a monitored system load before returning the host to service.
