Fans EFB0412LA 40×40×10mm 12V 0.08A Ball Bearing Case Fan

SKU CH-AHMY-K9D4T

40 mm square case fan with ball bearing, 12 V and 0.08 A draw

  • Compact 40×40×10 mm footprint fits tight chassis spaces
  • Ball bearing design extends operational lifespan
  • Low 0.08 A draw minimises power supply load
  • 12 V standard voltage simplifies system integration

Compact 40 mm case fan for tight builds

The Delta EFB0412LA measures 40 by 40 by 10 mm and runs on 12 V at 0.08 A. Its ball-bearing motor is rated for quiet operation inside small-form-factor chassis or rack-mount gear. The slim profile fits where larger fans cannot.

Simple two-wire install; check connector polarity

The fan connects with a standard two-pin header so mounting takes only screws and a plug. Ball bearings resist dust better than sleeves but can develop a faint whine after long use. Verify the 12 V rail matches the 0.08 A draw before powering on.

Questions about this item

How can I verify the EFB0412LA is spinning at the correct speed after installation?

Connect the fan to a 12 V header and confirm it draws about 0.08 A; the ball bearing should run smoothly without rattling.

What comes in the box with the EFB0412LA and what must I purchase separately?

The package contains the 40×40×10 mm ball bearing fan only; mounting screws and any fan cable adapters are not included.
