If you want to use an FET to control the fan, the diagram below shows you how to connect the FET to the op amp. Keep in mind that you must insulate the tab of the FET. If the tab of the FET touches to ground, the fan will run. As an alternate FET, you can use an IRFIZ44...
Figure 1 shows the schematic diagram of the PWM cooling FAN controller device. The heart of the circuit is an ATTiny13 microcontroller [1]. It reads the temperature values and decides what to do with the FAN, Relay, and the Buzzer. Figure 1: Schematic diagram of the PWM cooling Fan cont...
To determine which standard a motherboard uses for the tach signal, check the voltage across the pins on the motherboard fan socket with an oscilloscope; there should be 0 V (ground - black), +12 V (power supply - red).For the tach signal, the wire is usually yellow or white, ...
