Description

In this video, I built a temperature controlled fan circuit using an LM358 op-amp, NTC thermistor, and a 5V relay. The fan automatically turns ON when the temperature rises and turns OFF when the temperature drops. This automatic fan controller is ideal for cooling electronic circuits, inverter boxes, power supplies, and DIY cooling systems at home. The circuit is simple, low-cost, and beginner-friendly.
