  • Adjustable airflow with 3V–12V variable speed controller
  • Wide voltage compatibility from 100V to 240V at 50/60Hz
  • Versatile cooling for cabinets, grow tents, and electronics
  • 140mm by 25mm AC fan with integrated speed control
  • Quiet operation tuned via multi-speed controller settings

140mm AC fan with speed control

The LORDWORLD 140mm by 25mm computer fan connects directly to AC mains at 110V, 120V, 220V or 240V. A built-in variable speed controller lets users adjust airflow for enclosures such as server racks, audio cabinets or reptile vivariums. It suits DIY builders who need active cooling without a separate power supply.

Sustained airflow at chosen speed

The controller accepts 100V to 240V input at 50Hz or 60Hz and delivers a 3V to 12V output up to 2A. This allows the fan to run continuously at a fixed, user-selected speed rather than cycling on and off. Steady airflow maintains stable temperatures in wine cellars, biltong boxes or grow tents over long periods.

Mains-powered speed regulation limits

Because the unit draws power from the wall outlet, its maximum airflow is capped by the 12V 2A output rating of the controller. The fan cannot exceed this electrical limit regardless of the AC voltage supplied. Installations needing higher static pressure or greater volume must use a different power architecture.

Questions about this item

How much power does the controller draw when the fan runs continuously at full speed?

The speed controller accepts 100-240 V at 50/60 Hz and outputs up to 12 V at 2 A, so maximum draw stays within that 24 W envelope.

What power connection does the unit need that my existing setup might not already have?

It plugs straight into a mains socket (110-240 V) and the fan leads attach to the controller’s low-voltage output terminals.

Will the 140 mm fan’s mounting holes line up with the screw pattern on my older 120 mm case openings?

The fan measures 140 mm across, so it will not match a 120 mm hole pattern without an adapter bracket.
