Cooling fans have been used in equipment and devices for several years to aid in the prevention of overheating of the internal components. Internal components, especially electrical components, when getting overheated, can malfunction and may eventually cease to function at all. Electrical components may also catch fire, if not equipped with an auto shut-off feature, creating a major safety hazard.
While it is easy to see that the use of a cooling fan can greatly affect the long term capabilities of a machine, is there anything that can be done to maximize the life of the cooling fan? The answer is trickier than one may think. While there are a few things that can be maintained to help aid in the long term life of the fan they are a mechanical part. Mechanical parts have proved over the years that very often, for no apparent rhyme or reason or fault of the owner or manufacturer that they sometimes malfunction. However paying attention to a few aspects and by making repairs and adjustments as they are needed can only benefit the equipment.
Always make sure that the fan and its various components are cleaned often. This includes the filter, the fan blades as well as any guards over the fan. This will help to keep any debris or dust from inadvertently making its way into the equipment. It will also ensure the proper amount of air flow is making its way into the equipment maximizing the effectiveness of the fan. Also by changing the filter if it is excessively dirty or grimy and when suggested by the manufacturer, will help it keep excessive dirt out of the machine in the future.
Listening for abnormal noise can be a major way of determining issues with a fan. Fans can have bent blades or something may have made its way into the fan and could be brushing up against the blade as it is going around. No matter what is causing the noise, investigating it could keep a minor repair from becoming a major one or save from a total replacement of the fan in the long run.
Keeping a fan operating optimally also includes letting it get proper airflow. Keeping it clean is one way but also by making sure it does not get blocked by other equipment, walls, etc. will make sure that it has proper access to air flow. This will keep the fan working at its most efficient because it will be getting the air it needs to cool the machine effectively.
The life of a fan may also be determined by the right fan being used for the job that it is intended. If a fan is trying to do a job too large for its size it may not only be overworking the fan, it also may be damaging the equipment and its components due to not getting cooled adequately. To ensure the fan is the correct size always refer to factory suggestions or consult with a professional. Some fan accessories, such as a tray assembly, even allow for a second fan to be installed to aid the first fan in maintaining optimal machine temperature.
Just like any type of equipment, various aspects of a fan could cause it to malfunction. However by staying vigilant and tending to it as a way to prevent small problems from turning into larger ones can help it have a long life as it helps protect its device from overheating. From installing an extra fan via an assembly tray or simply keeping it clean and free of debris there are very simple ways of maintaining the life a cooling fan
