#ThermalFan

In this video , I have shown the circuit of Automatic Temperature Controlled Fan Circuit. I have also posted the PCB files. A Transistor is used as Thermal Sensor. This is a very good circuit to keep the temperature of Audio amplifier in control. You can adjust the temperature setting by preset. A CPU Fan of 4 inch size fan can be used with this circuit. For high power DC fan , please choose Higher power Transistor .
The circuit is based upon 741ic
Transistor used as temperature sensor
preset used for setting the temperature,
circuit requires 12 volt regulated supply.
can be made on multipurpose pcb easily.
Cost is very less around 100 INR.
Below is the Link of PCB Files of the project.
