Server Inverter Cooling

The Zyvpee DV12038B12H PS02 is a 120x38mm case fan built for Lenovo inverter cooling. It runs on 12V at 4.5A through a 4 Pin connector and uses a 2 Ball bearing. The black non-LED housing is designed for server environments.

Suited for 12V 4.5A inverter bays

This unit fits systems that require the exact 12038 form factor and the Lenovo 31-053745 pinout. Builders needing a lower amperage fan or a different mounting pattern should look elsewhere because the electrical and physical interfaces are fixed.

4.5A current draw at 12V

The 4.5A rating is the single specification that determines whether the power delivery and connector can support this fan. Verify the header and wiring match before installation.

Questions about this item

Which Zyvpee DV12038B12H PS02 version suits my Lenovo 31-053745 inverter bracket?

This model matches Lenovo part 31-053745 and is built to the 120x38mm form factor with a 4-pin connector; select it when your server or inverter tray calls for that exact size and pinout.

What does the 4.5A rating mean once the fan is installed?

At 12V the fan draws up to 4.5A, so the system’s 12V rail must supply that current continuously; plan your power budget and wiring accordingly.

What does the 4-pin connector control in practice?

The four pins provide power, ground, tachometer feedback and PWM speed control, allowing the motherboard or fan controller to vary RPM based on temperature.
