Lustful Encounter XY-FS USB Fan Speed Controller: Adjustable voltage potentiometer for stepless speed control
For the DIY enthusiast or home office worker tired of noisy fans, this USB fan speed controller offers precise airflow management. It transforms a basic USB fan into a customizable cooling tool, perfect for quieting a workspace or adjusting airflow for comfort during long hours at your desk.
Unlike typical controllers, its BUCK/BOOST converter handles a wide voltage range, so you can fine-tune speed smoothly without the hum of PWM. The knob doubles as an on/off switch, letting you quickly silence the fan when you need focus. Plug it into any USB port, connect your fan, and adjust the voltage to find your ideal breeze—whether for cooling electronics or personal comfort.
