75×75 mm projector cooling fan

This 75 mm square DC fan runs on 12 V and draws 2.91 W. It is built to fit projector housings and similar tight enclosures that need focused airflow. The three-wire connection allows speed monitoring or control. Buyers who need a larger frame or higher static pressure for dense radiators should look elsewhere.

Replaces worn projector fans

When the original fan becomes noisy or stops spinning, this unit restores the intended cooling path without modification. The 75×25 mm footprint matches the factory mount, so the swap is direct. If the chassis requires a different voltage, connector pitch or thickness, this model will not fit.
