40 mm 24 V Ball-Bearing Fan

This 40 mm square cooler uses an NMB 4015 motor running at 24 V and 0.06 A. The three-wire connector provides speed feedback for system monitoring. It is aimed at compact industrial or embedded builds that need a low-profile air mover.

Sustained Operation with Ball Bearing

The ball-bearing design maintains consistent rotation during continuous duty cycles. Steady 24 V input keeps airflow stable without the voltage droop seen in shorter bursts. No LED lighting means no extra thermal load inside tight enclosures.

Check Voltage Header and Clearance

Verify your board or controller supplies a 24 V three-pin header before ordering. Confirm the 40 mm footprint fits the mounting holes and that the 15 mm thickness clears adjacent components. The 3-wire plug must match the pinout expected by your fan controller.

Questions about this item

How much noise and heat does the 40 mm ball-bearing fan produce when running continuously at 24 V?

The 40 mm ball-bearing fan draws 0.06 A at 24 V, giving low power draw and modest airflow for continuous operation.

What connector and voltage source must my system already provide for this 3-wire cooler?

A 3-pin fan header supplying 24 V DC is required; the cooler has no built-in voltage converter.

Will the 40 mm square frame with 3-wire lead fit the mounting holes and fan header on my older motherboard?

The cooler uses a standard 40 mm square footprint and 3-wire connector, matching legacy 40 mm mounting patterns and headers.
