Hello Everyone !I would like to operate a 12V BLDC fan in isopropanol. A DV fan is out of the question because of the sparks. I would prefer if I could connect the fan to a power bank and it would run immediately. Is there a ready-made driver that transforms the voltage of the Powerbank to 12 V and sends a PWM signal? Would it be possible to connect a DC-DC converter to the power bank and then a driver?
