From the project
This is a USB powered (5v) PWM Computer Fan Controller
This fume extractor is made with a 120 mm PWM (4pin) 12V PC Fan. You can use any 12V PC Fan as long as the power consomption doesn't exceed 500mA over 12V. It has to be a 12V fan as the power supply is converting 5V USB to 12V. 24V Fans won't work. I personally use a Noctua NF-F12 industrialPPC-3000 PWM and it can blow air along 6 meter of 80mm aluminium duct even at half speed.
