  • 43 CFM air volume clears heat from tight switch chassis

  • Double ball bearing design rated for 10.0000 hours at 25 °C
  • 4-pin 3-wire connector with stall alarm simplifies drop-in replacement

Product identity

The SXDOOL EFB0412HHD-ROO is a 40 mm square, 20 mm thick case fan built by Delta. It spins at 8200 RPM on 12 V DC and draws 0.15 A, delivering 9.43 CFM of airflow for targeted cooling in compact enclosures.

Compatibility checks

Verify that your device accepts a 40X40X20 mm fan with a 4-pin, 3-wire connector on a 2.5 mm pitch terminal block. The wiring uses black for ground, red for 12 V and white for the stall-alarm signal, so the header must match that pin-out.

Sustained-load behaviour

Double ball bearings give a rated service life of 10.0000 hours at 25 °C and 45–85 % relative humidity. The stall-alarm function continues to report fan status during continuous operation, and noise stays at 30.5 dBA while the 1.8 W motor maintains steady airflow.

Domande su questo articolo

What comes in the box and is a connector or cable needed separately?

The fan ships with a 20 cm lead terminated in a 2.5 mm 4-pin 3-wire plug; no extra cable is required if your device uses that connector.

Which version matches a 12 V 0.15 A 8200 RPM requirement?

The EFB0412HHD-ROO is the only model listed and meets 12 V, 0.15 A, 8200 RPM, 40x40x20 mm dimensions and stall-alarm function.

What does 9.43 CFM at 30.5 dBA mean inside a switch chassis?

It delivers 9.43 CFM airflow at 30.5 dBA, enough to clear a fan-fault alert on H3C 3600, 5600 or S3100-52P units and keep the status indicator normal.
