Compact USB-powered cooling

This 120 mm fan draws 5 V from any USB 1.1 or 2.0 port and spins at 1200 RPM to deliver 45-50 CFM. The hydraulic bearing is rated for 35000 hours of continuous operation. A 100 cm cable and mounting hardware are included for quick installation.

Airflow and acoustic profile

At the rated speed the fan moves 45-50 CFM while producing 10-15 dBA, making it suitable for noise-sensitive spaces such as bedrooms. The specifications indicate the 1200 RPM variant prioritises quiet running over maximum airflow; the higher-speed 2000 RPM option is noted as louder and better suited to open areas.

Integration and limitations

The unit requires a free USB port capable of supplying 0.2 A and 120 x 120 x 25 mm of clearance with four screw holes or the supplied foot columns. It adds no LED lighting and includes a protective net for safety. Builds needing higher static pressure, PWM control or more than 50 CFM will need a different solution.

Questions about this item

Will the USB 1.1/2.0 connector on this 120 mm fan work with the older USB ports on my router or set-top box?

Yes, the fan draws 5 V at 0.2 A from any standard USB 1.1 or 2.0 port, so it will run on the older ports found on routers, TV boxes and similar devices.

How can I confirm the fan is running at its rated 1200 RPM and staying within the 10–15 dBA noise range after I install it?

Listen for a barely audible hum — 12 dBA is whisper-quiet — and check that airflow through the protective net feels steady; the hydraulic bearing is rated for 35 000 hours at this speed.

Does the package include the protective net and mounting screws, or do I need to buy them separately?

The box contains one 120 mm fan, one 12 cm protective net, four foot columns and eight screws — everything needed for installation.
