LORDWORLD 120mm USB Fan Cooler L/M/H Speed Control

USB-Powered 120 mm Cooling Fan

The LORDWORLD 120 mm USB fan cooler draws 5 V power from any standard USB port, making it a compact cooling add-on for routers, modems, DVRs, game consoles, TV boxes, fridges, incubators, aquariums and ham radios. It also serves as a direct replacement fan for small enclosures that need active airflow. Buyers without a free USB socket or who require higher static pressure for dense radiator stacks should look elsewhere.

Flexible Placement With Rubber Feet

Four silicone rubber feet absorb vibration and let the unit sit flat or stand upright on any surface without scratching the chassis. The USB cable removes the need for a dedicated fan header or molex adapter, so the cooler can be repositioned quickly when device layouts change. No mounting screws or brackets are included, so permanent case integration needs separate hardware.

Three-Speed Controller And Dual Ball Bearings

An inline L/M/H switch cycles through high, medium, low and off settings, letting the user match airflow to a noise floor between 9.3 and 16.8 dBA. Dual ball bearings rated for 50000 hours keep the rotor stable in any orientation and extend service life well beyond sleeve-bearing alternatives. No software or PWM signal is required for speed changes.
