  • 12 V operation suits standard PC headers
  • Nidec build ensures reliable cooling

Compact 40 mm case fan for tight builds

The Nidec U40X12MLZ7-53 measures 40 by 40 by 10 mm and runs on 12 V at 0.05 A. It fits small-form-factor cases, rackmount chassis and embedded boards where larger fans cannot be mounted. Builders working with limited clearance will find it a direct fit for 4010 mounting holes.

Steady airflow at low current draw

At a continuous 0.05 A the motor maintains its rated speed without the current spikes seen in higher-power fans. This keeps heat output predictable inside sealed enclosures and avoids voltage sag on shared 12 V rails. The fan is not suited for high-static-pressure heatsinks or radiators that demand greater airflow.
