The SparkFun Inventor's Kit (SIK) is your map for navigating the waters of beginning embedded electronics. 40x20mm size ideal for 1u applications or replacing fans in network and storage equipment routers, switches, NAS etc. Insert the male headers into the 3 or 4 female sockets on the servo motor and the fans(see figure above for fan pin instructions). Enable CPU Fan Setting. For fans that already have PWM (4 wire), all you need is to connect your PWM pin from the arduino straight to the blue wire of the fan, GND to arduino and power supply and + to the power supply. The problem (you will find out if you read my whole thread) is with the stepping of those PWM circuits.
