Compact 5 V Case Fan

The Delta EFB0505HA 5010 is a 50 mm square frame fan that runs on 5 V and draws 0.25 A. A double ball bearing supports the rotor and a tachometer wire reports speed to the motherboard or controller. It fits the 50 × 50 × 10 mm mounting pattern used in tight chassis and small-form-factor enclosures.

Ideal for 5 V Headers

Builders with 5 V fan headers who need a low-profile cooler for confined spaces will find this unit suitable. Buyers who require a different voltage or a larger frame should consider other options because this model is fixed at 5 V and the 50 mm square footprint.

Questions about this item

What does the 0.25 A current draw mean for a 5 V header?

The fan draws 0.25 A from a 5 V header, keeping power use low and leaving ample headroom for other devices on the same fan controller.

How does the tachometer output work with standard motherboard headers?

The tachometer wire sends a speed signal to the motherboard so the BIOS or fan-control software can monitor and regulate RPM in real time.
