Intelligent PC Fan Controller
In a modern PC you will find a number of fans for removing the heat that is generated. These can’t always be controlled individually by the PC motherboard. With the help of the circuit described here you can actively control up to six fans, while the temperature can be measured in various places inside the PC case using a number of sensors. A PC program is used to configure and monitor the fans, which communicates with the fan control board via a USB link.
