The AC cooling fan has become an essential component in nearly all modern electronics products. These fans supply the apparatus with cool air and create efficient air flow over the device so that it may operate correctly and at its full ability.

AC fans are found in a wide variety of electronic appliances and are responsible for the cooling of essential computing parts that can overheat or lose performance quality due to inconsistent temperatures in the device during use. In the same way that cars use radiator fans, a radiator, and coolant in order to maintain a healthy operating temperature while driving, cooling fans in electronics supply the device with the fresh air and cool temperatures that can rob an appliance of its performance quality.

How the AC Cooling Fan Works

These fans works in the same way that any standard fan operates. The fan’s purpose is to ensure cool operating temperatures and in order to achieve those temperatures the fan will spin at variable rates in order to supply the device with fresh air. Working with information provided by the device it is cooling, the fan supplies just the right amount of cool air to the components, protecting against heat that can harm the electronics and cause drop-offs in performance.

The fan’s angled blades force air outside of the device to move into the device in a single direction. The aerodynamic shape of the blades forces air from one side of the housing through the middle and out to the other side at an accelerated rate. The cool air is rushed from the outside into the peripheral, creating a steady current of moving air. The side that brings air into the fan generally faces away from the device that it is cooling, allowing for the cooler air surrounding the device to enter. This helps eliminate settling dust, as well as helps keep temperatures in the device cool for optimal performance.

The cool air flow is regulated by a mechanism similar to a house’s thermostat. A small temperature gauge inside the device will decide how much airflow is needed to cool the device based on its performance demands. The fan’s blades will then spin either faster or slower depending on the needs of the device (how hard it is working, how long it has been on for, surrounding room temperature, etc…) until temperatures are regulated. The cooling fan will then run at an idling speed in order to maintain these temperatures or completely shut down if its use is not needed by the computer.

Sizes and Shapes of Computer Fans

Today, fans come in an assortment of shapes, sizes, colors, and voltages to help fit perfectly into any device. The title of “AC Fan” means that the cooling fan operates on an alternating current. Other fans can run on direct current (shortened to DC) depending on the type of power supply for the fan and the voltages and current type for the accompanying device that the fan will cool. It is important to double-check your own power supply and current-type before purchasing either an AC fan or a DC fan, as certain fans won’t work with certain currents or power supplies.

The size and shape of a self-contained cooling apparatus is an incredibly important variable to consider when deciding what size or type of fan to purchase for your electronics project. Based on the size of the project and the potential temperatures that could be reached in your device, it is important to understand and select the correct cooling fan for your project.

Most AC fans are categorized by a couple of different measurement systems. In addition to picking the right size of fan when ordering, it is important to understand what unit and variable is being measured during the categorization of the apparatus. The standard unit of measurement for the fan size is in millimeters (shortened to “mm”). These fans will range in size from 60mm to 150mm square.

While the size of the fan does help to determine the cooling capability of the fan, the speed and power of the fan cannot be ignored when searching for the right cooling system for your project. Fans that can spin at higher rotations per minute (rpm) will funnel more air into the machine than a slower fan. Generally, these more powerful fans can cost more per unit and their extra power may not be necessary for your project. Be sure to understand your device’s needs and limitation before purchasing an AC fan to ensure that your fan fits your device.

Computer fans also come in a variety of shapes and sizes. Some AC fans will have standard square dimensions that allow you to easily fit the fan into your electronic device, while others will vary in shape. Depending on what element of your project you are trying to regulate temperatures for, it is important to know what shape mount and casing you will need for your AC fan. In some cases, it may be necessary to order or fabricate your own mount for the fan in order to achieve proper cooling in your electronic device.

Overview: Cooling Systems

The AC cooling fan has also become a statement of style for some computer builders. Certain fan assemblies will come with multi-colored lights or lights that change color to add an extra design touch to the capsule. Additionally, manufactures may use clear plastic to construct the fan, allowing for the lights or other added on designs can be seen inside of the computer. Liquid cooling systems are also available, but can be very expensive and are rarely utilized in standard electronics. Overall, the AC fan is a key piece of any electronics assembly puzzle. These high-speed fans allow for computers and electronics to operate at their peak performance without facing damaging heat would limit your device’s capabilities. With the right AC cooling fan, one can have a great computer that is guaranteed to have better performance and longer durability.
