3 pin connectors are usually used for the smaller chassis fans with lower power consumption. The rated current of the main molex connector is 6a per contact. Diagram for connecting computer components this is the monitor cable connector. If you want to install a normal pwm fan you have to connect the following pins.

3 pin connectors are usually used for the smaller chassis fans with lower power consumption. 4 pin connectors are usually used by cpu fans with higher power consumption. Take note of the connection to the left of the all the computer wiring connections. 4 pin connectors are usually used by cpu fans with higher power consumption.

For a computer connection diagram click on the picture below in order to get a closer look at the ports in which your computer components will attach. Chassis and cpu fans may use either 3 pin or 4 pin power connectors.
