Two small black 50mm USB blower fans with speed controller

LORDWORLD

LORDWORLD 5015 USB Blower Fan 5V 50mm 2 Pack

SKU CH-6BFY-X6FST

Two 50 mm USB blower fans with variable speed control deliver 2.91 CFM at 3500 RPM for compact DIY cooling

  • Compact 50 mm blower fits tight DIY spaces
  • USB power lets you run it from chargers or power banks
  • Variable speed controller adjusts airflow to the task
  • 91 CFM at 3500 RPM delivers focused cooling
  • Quiet 25.7 dBA operation suits noise-sensitive setups

Versatile USB blower fan kit

This two-pack of 5015 blower fans delivers focused airflow for 3D printers, humidifiers, aromatherapy devices, small electronics, vivariums and RV refrigerators. Each unit measures 50 mm by 50 mm by 15 mm with a mounting spacing of 2.24 inches. They connect to any standard USB port on chargers, laptops or power banks for instant operation.

Low noise and minimal power draw

Rated at 5 V, each fan draws 0.12 A and consumes 0.5 W while spinning at 3500 RPM. The sleeve bearing produces 25.7 dBA of noise and provides 2.91 CFM airflow with 0.45 In H2O static pressure. This profile suits quiet personal cooling and low-power USB sources.

Steady output for extended runs

The brushless motor is rated for a 35000-hour lifespan under continuous use. Performance remains consistent during long printing sessions or overnight vivarium ventilation without the drop-off seen in short-burst cooling. Buyers needing higher airflow or larger duct diameters should consider other form factors.

Questions about this item

How do I mount the 5015 blower fan and what spacing do I use?

The fan measures 50 mm by 50 mm by 15 mm and uses a mounting spacing of 2.24 in. Align the four corner holes to that pitch before securing with screws; the common mistake is drilling to a 50 mm grid instead of the inch-based spacing.

When will the sleeve bearing need replacement?

The manufacturer rates the fan for 35000 hours at 5 V. In continuous use that is roughly four years; plan to swap the unit once noise rises above the rated 25.7 dBA or airflow drops below 2.91 CFM.

What thermal limit appears first during sustained operation?

At 0.5 W draw and 3500 RPM the sleeve bearing temperature rises steadily; the 35000-hour lifespan rating assumes the bearing stays within its thermal envelope, so prolonged duty in a sealed enclosure will hit that bearing-life limit before the 5 V supply or 0.12 A current rating becomes an issue.
