Compact 40 mm case fan for tight builds

This 40 x 40 x 20 mm Sunon fan uses a three-wire connection and draws 1.4 W of power. The 4020 frame fits small-form-factor cases, embedded appliances and replacement spots where larger coolers cannot mount. Supplied in a 100-piece lot for volume deployments.

Straightforward three-wire mounting

The three-wire lead connects directly to standard motherboard or controller headers without adapters. Verify header spacing and polarity before powering the system to avoid reversed rotation. The thin 20 mm profile can snag on tight cable runs, so route wiring clear of the frame during installation.
