This simple circuit can be placed inside the PC to monitor the temperature near the processor. It gives warning beeps when the temperature near the heat sink increases abnormally. This helps to ...

This circuit can be used to determine the core temperature of your PC’s CPU and display it on a monitor (Fig. 1). Installing such a circuit can help to ensure that your system’s cooling is ...

As shown in the circuit diagram the heatsink monitor is made of 2 opamps that are set as window comparators. The input voltage level is set by the thermosensor IC LM335. This voltage level increses ...
