Replacement fan for ADDA AB0712HB-UB3 notebooks

This 12 V, 0.30 A three-wire cooler uses double ball bearings and matches the original ADDA AB0712HB-UB3 specifications. It is intended for technicians or owners servicing compatible notebook CPU cooling assemblies. The unit is supplied new and ready for installation.

Practical limits of the 3-wire 12 V interface

Speed reporting relies on the tachometer signal; PWM control is not available on this three-wire design. Voltage regulation determines the operating point, so the host must provide a stable 12 V supply. Builders needing variable-speed headers or four-wire PWM fans should select a different model.

Domande su questo articolo

Should I choose the 12 V .30 A version for my notebook?

The 12 V .30 A rating matches the original ADDA AB0712HB-UB3 specification; select this version if your notebook requires those exact electrical values.

What does the 12 V .30 A rating mean once the fan is installed?

It indicates the fan draws 0.30 A at 12 V, so the motherboard header must supply that current for the double ball bearing cooler to run at its designed speed.
