The Importance of Plastic Fan Guards for Computers Computer cooling is a very important feature that plays a large role in extending the lifespan of any machine by reducing or removing waste heat produced by several of the computer components. Fans are usually used in computers to keep components within a reasonable range of operating temperatures. There are a number of computer components that are very susceptible to breakdown, malfunction, or even permanent failure if they overheat to a certain extent. This is why a properly functioning fan is such an important safety feature as the damage to or breakdown of components can lead to a loss of data. Components are usually designed in such a way as to generate as little heat as possible, and computers including their operating systems are often designed to cut power consumption and the accompanying heat generation according to workload. However, more heat can still be produced, which can then be difficult to reduce or remove without paying the proper attention to optimal cooling. There are a number of ways that computers use cooling techniques, and fans are only one of them. In this case, fans are used when natural convection is adequate to remove the excessive heat.
In front of the fan in any computer will be a fan guard, and these are generally constructed from plastic. The purpose of the fan guard is to provide a physical barrier in front of the rotating fan blades. This can prevent other computer components from accidentally coming into contact with the spinning fan blades and causing damage. Although computer fan guards can be constructed from either metal or plastic, plastic is generally the preferred material, as it has a wide range of benefits pertaining specifically to the use of computers. Another component of the fan itself is the fan filter. The fan filter can also be constructed from plastic and it serves the purpose of purifying the air that the fan is generating. This means that less dust and impure particles will be circulating, which is healthier for people and animals, and better for the longevity of devices and appliances. A fan that utilizes a plastic fan guard and a filter will drastically reduce the level of noise it makes, which is ideal in office settings where computers are typically used. A noisy fan can be a distraction to either the employee using the computer, or their fellows, but a plastic fan guard and filter can help reduce this noise to a minimum, which sharpens the focus in the workplace.
