AC cooling fans are essential parts of all modern electronic appliances. They allow our electronics to run smoothly and at temperatures that are healthy for these devices to operate at by supplying a steady stream of cool air.

AC fans are in nearly every electronic device that we use through our day-to-day lives. They are responsible for protecting essential pieces of these devices from breaking down or losing their performance capabilities. Similar to the cooling fans in an automobile engine, these devices supply fresh, cold air to the critical components of some of our most sophisticated machines.

The Way AC Cooling Fans Function

Computer and electronics AC fans function in the same capacity as any regular household fan. The main purpose of these fans is to ensure that acceptable temperatures are maintained in an electronic device. The blades spin at different rates proportionately to the required amount of cooling. Together the device and fan work to maintain optimal temperatures, by maximizing performance and longevity and protecting against harmful overheating.

AC fans use aerodynamically constructed blades to help create a vortex of air, pushing cooler air into the device. The spinning blades force the air to move in a specific direction. This directional movement of air is dictated by the orientation of the blades. As the blades spin they both suck air from the surrounding outside area and propel the new air through the AC fan and away on the other side. The side of the fan that sucks new air in is generally located facing outwards, in order to supply the computer with fresh cooling air. It is also common to see multiple AC fans facing in opposite directions in order to create a current of fresh air.

In order to maintain a constant temperature, the computer and the fan work together in the same way that a thermostat interacts with an air conditioning unit. As the computer works harder or is placed in a warmer environment, it tells the AC fan to supply the machine with an increased air flow. The fan will then spin faster in order to meet the computer’s request for lower temperatures, thus cooling the machine. From there, the mechanism will either enter an idling phase in order to maintain the temperature or it will completely shut off if, its services are no longer needed by the computer.

Different AC Cooling Fans

Computer fans come in wide assortment of styles and specifications. What makes an AC fan unique is the fact that it runs on alternating current, hence the abbreviation “AC”. The alternative to an AC fan is a DC fan which runs on direct current. These supply no difference in performance or ability, but they do need to be checked for compatibility with the other pieces of your electronics project. Specifically, AC fans will need an AC compatible power supply in order to be able to function properly. Be sure to check your power supply to avoid complications.

Cooling devices range in size from fans as large as 150 millimeters and larger, all the way down to mechanisms as small as a 60 millimeter (approx. two inch) square box. The larger the fan, the more air the fan can supply to your machine, keeping it cool and performing strong.

Additionally, the devices are rated on their power and speed. Different fans will be capable of rotating at different maximum revolutions per minute, funneling different amounts of cooling air into your machine. The more powerful mechanisms tend to be more expensive and may not even be needed for your specific project. Be sure to check that you are purchasing the correct size and power AC fan.

Lastly, depending on where you are trying to mount your new cooling system, it is important to consider shape mount and casing you will need for your AC fan and its housing. Many fans come in different shapes and sizes and knowing how you plan to attach your AC fan will affect how well it can regulate temperatures in your device. If the fan does not fit, you make have to purchase gaskets or fabricate fasteners for the cooling fan to attach to.

Using Your Cooling Fan

When used correctly, computer fans are one of the most helpful and important pieces of any electronics or computer construction project. This vital piece of equipment provides your peripheral with the cold air it needs to ensure performance and longevity. While the incredible number of classifications and styles can be overwhelming, the perfect fan is waiting to provide your computer with the cool air it has to have in order to work the way you expect it to.
