The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Typically, CPU fan noises are heard when you reboot your PC (the whirring sound you may have heard upon startup) and it goes on to decline as the startup process completes. The purpose of fans on your ...
