Temp sensor and PWM for 12v fan2 wire or 4 wire ...

Jul 17, 2018· 2. Im also seeing very efficient computer case fans. Some are 3 wire, some are 4 wire. I think the 4 wire fans are designed to connect to a computer? Wondering if i can use just 2 wires from a 4 wire fan and somehow attach to a temp sensor or timer. Would be great if my PWM controllers worked with the small computer fan.

Suppressing Acoustic Noise in PWM Fan Speed Control .

control is to use low frequency pulse width modulation (PWM). However, PWM fan speed control can sometimes introduce unwanted acoustic noise at a frequency equal to that of the PWM itself. This is especially noticeable when PWM control is used with higher operating current (>300 mA) fans and at low operating speeds. This application note ...
