Delta EFB0812EHF-R00 80 mm Server Fan

The Delta EFB0812EHF-R00 is an 80 mm DC axial flow case fan built for server and industrial cooling. It runs on a nominal 12 V supply and draws 0.68 A for 8.16 W of input power. Double ball bearings support the 4100 RPM rated speed and 120 g net weight.

Suits high static pressure 80 mm bays.

This fan fits 80*80*32 mm mounts that need strong airflow against resistance. The 11.5 mm H₂O static pressure and 62.0 CFM volume serve dense server chassis and drive arrays. Buyers who want low noise should look elsewhere because the 45.5 dB-A rating is noticeable in quiet rooms.

4100 RPM at 12 V decides fit for 80 mm server slots

The single specification that decides compatibility is the 4100 RPM rated speed at the nominal 12 V input. It sets the 62.0 CFM airflow and 11.5 mm H₂O pressure that determine whether the fan clears your component thermal load. Verify the 7.0 V to 13.2 V range matches your header before installing.

Questions about this item

What power connector does the 12 V 0.68 A Delta EFB0812EHF-R00 require?

The fan runs on DC 12 V and draws 0.68 A through a standard 3-pin or 4-pin PWM header; ensure your motherboard or fan controller supplies 7.0 V to 13.2 V.

Will the 80 mm 4100 RPM unit fit in a chassis designed for 32 mm thick fans?

Yes, the frame measures 80 x 80 x 32 mm, so it matches the 32 mm depth used in many server and industrial enclosures.

How can I confirm the fan is delivering its rated 62.0 CFM at 45.5 dB-A after installation?

Monitor the RPM in BIOS or fan-control software — it should read close to 4100 RPM — and verify airflow direction matches the arrow on the housing.
