40 mm 24 V Server Fan

The SXDOOL EFB0424LD is a 40 mm square case fan designed for 24 V DC operation. It uses a double ball bearing and a three-wire power connector to deliver 5.5 CFM at roughly 5000 RPM with a noise level of 22 dBA.

Suited for 24 V Server Chassis

This fan fits server and industrial enclosures that supply 24 V directly to the fan header. Builders whose systems provide only other voltages cannot use it without a separate voltage conversion solution.

24 V Operating Voltage

The unit is rated for 24 V at 0.05 A with a speed of 5000 RPM ±10 %. That voltage requirement is the single specification that determines whether the fan will work in a given build.

Questions about this item

Should I pick the 24V version or a different voltage?

This model runs on 24V DC at 0.05A rated current, so choose it only if your system supplies 24V.

What does 5.5 CFM actually move in a tight server chassis?

At 5000 RPM the fan pushes 5.5 CFM through a 40x40x20mm frame, enough for spot cooling in dense enclosures.

How does the 3-pin connector limit speed control?

The 3-pin plug delivers fixed 24V power; speed varies only with voltage changes, not PWM signalling.
