A PWM-capable fan is usually connected to a 4-pin connector (pinout: Ground, +12 V, sense, control). The sense pin is used to relay the rotation speed of the fan and the control pin is an open-drain or open-collector output, which requires a pull-up to 5 V or 3.3 V in the fan.
Most desktop personal computer power supplies are a square metal box, and have a large bundle of wires emerging from one end. Opposite the wire bundle is the back face of the power supply, with an air vent and an IEC 60320 C14 connector to supply AC power. There may be a power switch and/or a voltage selector switch.
Fan speed can also be reduced more crudely by plugging them into the power supply's 5-volt line instead of the 12-volt line (or between the two for a potential difference of 7 volts, although this cripples the fan's speed sensing). [11] Most fans will run at 5 volts once they are spinning, but may not start reliably at less than 7 V.
This connector is used when connecting the fan directly to the power supply. It consists of two wires (yellow/12 V and black/ground) leading to and splicing into a large in-line four-pin male-to-female Molex connector. The other two wires of the connector provide 5V (red) and ground (black too), and are not used in this case.
