Cooling fans and blowers are essential to systems that produce a significant amount of heat like computers and other electronic components. Different systems are engineered to work with specific types of fans. Cooling fans come in all shapes and sizes as well as voltage, airflow, and case size. Some are even weather resistant and can stand up against the elements. It's important to know the specific type of fan your CPU / electronic component requires as fans and blowers are not universal. Be sure to reference the fan part number before you buy a replacement. Installing the wrong fan type can cause more harm to your computer / system.
