How a CPU Cooling Fan Works

A Central Processing Unit (CPU) processes the data and executes the programs of the computer and a CPU cooling fan keeps the processor from overheating. The electricity required by the processor generates a lot of heat when components are working. The harder they work, the hotter the processor gets. Irreparable damage can be caused if the processor overheats. It is vital to have a properly working CPU fan in your computer.

CPU Fan Location

A CPU fan is generally located at the back of the processor and is responsible for keeping all parts of the computer at the proper temperature level. Any heat that is generated by the working components is blown away by the fan, keeping them cool and operational. Available in a variety of sizes, cooling fans work in connection with the aluminum heat sink fan. Together they cool down the computer and any circulating hot air. Some computers have two CPU fans. One of the fans is responsible for bringing in cool air and the other dispels the hot air.

Keeping it Clean

It is important to keep the blades of the CPU fan clean. Dust or dirt can reduce the rotations of the fan blades, and the ability the fan to cool air. A poorly performing fan can eventually cause the computer to overheat causing permanent damage.
