Description

Keep your electronics and enclosures cool with this 12V DC brushless cooling fan, sized 90x90mm (9x9cm). A standard size widely used in PC cases, power supply units, network cabinets, 3D printers, and custom electronics enclosures, this fan delivers reliable airflow to prevent heat buildup in continuously running systems.

Built with a brushless DC motor, it offers quiet, efficient operation and a long service life compared to brushed motor fans. The square frame with corner mounting holes fits standard 90mm fan cutouts and enclosures, making installation straightforward. With a simple 2-wire (red/black) connection, it can be wired directly to a 12V power source or connected through a fan header on your control board or PSU.

Whether you’re cooling a PSU, ventilating a control cabinet, adding airflow to a 3D printer enclosure, or building a custom electronics project that runs hot, this 12V 90mm fan provides dependable, continuous cooling in a compact footprint.
