  1. 1

    Remove the computer case cover by removing the two screws located on the rear right of the machine. The side panel should slide off.

  2. 2

    Place a case fan against one of the fan ports located within your case. The location of these ports will be obvious, as they will be the only areas of your case that contain exhaust holes and areas for mounting screws.

  3. 3

    Screw the fan into position using the four mounting screws that came with your case fan.

  4. 4

    Connect the fan to your power supply by plugging the three- or four-pin power cable coming out of the fan into a like-coloured cable coming out of your computer's power supply. There will be only one way that these cables can attach.
