Updated: 04/26/2017 by Computer Hope

Alternatively referred to as a system fan, a case fan is located inside a computer, attached to the front or back of its case. Case Fans help bring cool air into and blow hot air out of the case. They are available in a wide variety of sizes, but 80mm, 92mm, and 120mm (12cm) with a width of 25mm are the most common. Below is an example of how a computer case fan may look.
