USB-Powered Blower for Tight Spaces

The PANO-MOUNTS 120mm blower fan runs from a standard 5V USB port and measures 120x120x32mm. Its moisture-proof construction survived a verified test immersed in 4cm of water for four hours at 70% humidity. The brushless motor delivers variable speed between 1300 and 2000 RPM. It suits builders who need exhaust cooling in confined areas such as media cabinets, RV refrigerators or inflatables.

Stepless Speed Controller Sets Airflow

A built-in stepless controller lets you tune the fan from low to high without fixed steps. At 0.309A the fan spins at 1052 RPM, moving 10 CFM at 45 dBA. At 1.042A it reaches 2082 RPM, pushing 21.87 CFM at 49 dBA. Intermediate points include 0.296A at 1215 RPM and 0.842A at 2518 RPM. This single adjustment replaces multiple fixed-speed fans and matches cooling to the exact thermal load.

Fits Any 5V USB Source Without Extra Wiring

The fan draws 0.3A to 1.2A directly from a USB-A port on a router, console, laptop or power bank — no mains adapter or motherboard header required. Its 32mm thickness fits shallow enclosures where standard 25mm fans cannot mount as blowers. The moisture-proof coating allows placement in damp or outdoor-adjacent locations. It is not for builders who need PWM motherboard control, addressable lighting or higher static pressure for dense radiator stacks.

Questions about this item

What does the 1300-2000 RPM range mean once the fan is running in a real machine?

At the low end the motor draws .309 A and spins at 1052 RPM delivering 10 CFM at 45 dBA; at the high end it draws 1.042 A at 2082 RPM for 21.87 CFM at 49 dBA, so airflow and noise rise together as you turn the dial.

What does the 5 V USB power connector cap in practice?

The USB port limits current to 1.2 A, which caps the maximum speed at roughly 2000 RPM and 21.87 CFM; you cannot exceed that without a higher-current source.

What does the 32 mm thickness require for mounting?

The frame is 120 x 120 x 32 mm, so you need a 120 mm square opening with at least 32 mm of depth clearance and four corner screw holes or a compatible bracket.
