Control 3 wire fan with arduino

WebOct 15, 2014 · When putting HIGH on the port the fan works perfectly at high speed, but when I want to lower the speed (say analogWrite(fanPin, 150)) it starts to make a humming noise. I believe this is caused by the use of PWM. What is the best way to control the speed of the fan without (too much) noise? ps. The fan is a Cooler Master 3-wire PC fan. WebJun 4, 2016 · Mfuon Leonard. 111 3. Add a comment. 1. Actually the Arduino Uno dc current per I/O pin is 40mA. When fan is connected directly to Arduino Uno, it cannot withstand, because the fan draws more-than 20mA current. The driver circuit provides sufficient current to rotate the fan. The TIP 121 can withstand up to 3A current.
