The fan runs continuously in many computers, it may not be necessary. A simple circuit controller can adjust the fan speed according to demand. This not only saves energy but also reduces s irritation fan noise. Only three components are required to enable the fan speed is controlled according to the cooling needs.
An adjustable voltage regulator that this circuit is the LM317 and two resistors form a voltage divider. One of the resistors is an NTC thermistor (temperature-sensitive resistor), while the other is a standard resistor.
