Smart cooling fan


This is an easy to build and smart cooling fan circuit, the smart means that this fan will start automatically when the temperature rises above a limited level, so to function this circuit properly place the NTC (thermister) near a device that is getting hot (eg.on an audio IC) so this fan does’t need to operate always, use a 12v 200ma or 100ma fan, and check the polarity of the fan when it connect to this circuit,Your comments will help me to design more circuits for you,
