Compact 12 V ball-bearing case fan

This 40 mm square frame fan runs on 12 V and draws 0.48 A, making it a direct replacement for small-form-factor power-supply or chassis cooling. The ball bearing reduces friction for consistent speed over long operating periods.

40 × 40 × 28 mm footprint fits tight mounting holes

Two-wire power leads connect to standard 12 V headers without adapters. The shallow 28 mm depth clears crowded PCB layouts and slim enclosures where thicker fans cannot be installed.
