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.

Key Features

12V DC Operation – Runs directly off standard 12V rails (PSUs, adapters, batteries)
90x90mm (9x9cm) Size – Standard fan size, compatible with common 90mm cutouts and brackets
Brushless Motor – Quiet operation, longer lifespan, and lower power consumption than brushed motors
2-Wire Connection – Simple red (+) / black (–) wiring for easy integration
Durable Frame – Sturdy plastic housing built for continuous-duty operation
Corner Mounting Holes – Standard 4-hole mounting pattern for secure installation
Continuous Airflow – Helps prevent overheating in enclosed electronics, PSUs, and cabinets
Wide Compatibility – Ideal for PSUs, PC cases, 3D printers, network cabinets, and DIY builds
