What is a computer fan?

Computer fans are found inside the computer case and help prevent various internal computer parts from overheating. Without them, your computer components can malfunction, get damaged, or even crash.

A computer fan can be used to push air across a heat sink.

A computer fan can do one of three things. First, it can pull cooler air from outside into the computer case; that is, he can draw air. Second, it can get rid of hot air inside the computer; that is, push the air out. Lastly, it can move air over a heat sink to cool another part of the computer, such as the central processing unit (CPU). A heat sink is a component that absorbs and dissipates heat. In this configuration, you can think of the computer fan and heat sink as a set that works together.

Fans can be used to cool a computer’s power supply.

A computer fan typically comes in a square frame, although round ones are also available. The usual sizes are 60, 80, 92, and 120 millimeters (about 2.36, 3.15, 3.60, 4.70 inches). The size, of course, depends on where the fan will be placed. The computer’s case or chassis is where fans are typically mounted. They can be installed behind, in front, on the sides or even on top of the computer case.

The CPU is a component that needs a computer fan to work well. The CPU is the most important chip in the computer; in fact, it is often called the brain. Therefore, CPU fans are vital to the well-being of the computer.

Computer fans are also used to cool chipsets, which are specialized sets of chips on the computer’s motherboard. Another common application is a graphics card. With the advent of high powered gaming and 3D graphics, graphics cards generate a lot of heat and graphics card fans keep them cool.

Fans are less used in hard drives and power supplies. The hard drive is where all your files are stored on your computer and hard drive fans help keep them from crashing. On the other hand, if a power supply overheats, your computer will have no power, so the power supply’s fans can also be important.

Computer fans also vary in the amount of airflow and speed of rotation. The amount of airflow is measured in cubic feet per minute (CFM), while the rotation speed is measured in revolutions per minute (RPM). A higher speed usually means more noise generated by the computer’s fan.

The computer fan can pull cool air out of the device to prevent it from overheating.
