Nidec 4015 40 mm 4-pin case fan

The Nidec 4015 U40R05MS1A7-57A07A is a square 40 mm by 15 mm fan with a 4-pin power connector that runs on 5 V at 0.08 A. It uses a maglev bearing and has no LED lighting. The part is listed as a cooler for the Xbox One Kinect 2.0.

Suits repairs that need an exact 5 V 4015

This fan fits devices designed for the 4015 form factor and a 5 V four-wire header. Builders whose systems only provide a different voltage header, or who require a taller heatsink assembly, cannot use this part.

5 V 0.08 A 4-pin power specification

The cooler draws 0.08 A from a 5 V supply through its 4-pin connector. That voltage and current rating is the single figure that determines whether the fan will operate in a given device.

Questions about this item

Does my motherboard need a 4-pin PWM header to power the 40mm Nidec U40R05MS1A7-57A07A cooler?

Yes, the cooler uses a 4-wire 4-pin connector that requires a matching 4-pin PWM header on the motherboard or controller for power and speed control.

Can the 5 V 0.08 A Maglev fan run on an older 3-pin header if I use an adapter?

A 3-pin header supplies only three wires; the fourth PWM wire would be left unconnected, so speed control is lost and the fan may run at a fixed voltage instead of responding to PWM signals.

How can I confirm the Maglev bearing fan is spinning correctly after installation?

Connect the 4-pin header, power on the system, and verify in BIOS or monitoring software that the fan reports an RPM value above zero and responds to PWM duty-cycle changes.
