12V Smart Fan Control Circuit Using IRFZ44N & NCT-5k Thermistor”

“DIY Auto Fan Controller with MOSFET & NTC Thermistor”

This project demonstrates an automatic 12 V fan control circuit that turns the fan ON or OFF based on ambient temperature. The circuit uses an IRFZ44N N-channel MOSFET and a NCT-5k / NTC thermistor. As temperature rises, the thermistor resistance drops, driving the MOSFET gate and switching the fan. A 3.9 k resistor is used to set the threshold and bias the gate.

Components used:
• IRFZ44N MOSFET
• NTC thermistor (5 k)
• 3.9 k (or ~4 k) resistor
• 12 V DC fan

In the video / demonstration, I’ll show how the threshold works, how to adjust component values, and tips for stability / hysteresis.
