Replacement fan for specific laptops

This 40 mm DC12V fan serves as a direct replacement for compatible laptop cooling assemblies. Buyers who need a different voltage, a larger frame or a four-wire PWM connector will not find those options here.

12 V three-wire power interface

The fan runs on a 12 volt supply with a three-wire lead that provides power and tachometer feedback. It lacks a fourth PWM wire so speed cannot be controlled by the motherboard; systems expecting PWM control will not regulate this unit.

Simple swap with part-number verification

Installation consists of removing the old fan and connecting the identical three-wire plug. The main risk is ordering the wrong variant; the supplier advises comparing photos and confirming the exact part number before purchase.

Questions about this item

Is the AD0412XB-G73 the only version available for this 40 mm fan?

The listing shows a single part number AD0412XB-G73; no alternative versions or capacities are offered.

What does the 12 V 0.15 A rating mean once the fan is installed?

It draws 0.15 A at 12 V, so the laptop's fan header must supply at least that current for reliable operation.

How does the 3-wire interface affect speed control?

The third wire provides a tachometer signal for RPM monitoring; voltage regulation on the 12 V line sets the speed.
