What Is Air Cooling?

Air cooling is a traditional method of removing or dissipating heat with a flow of air to cool an intended object. The objects in question can be electronic devices or mechanical ones, such as automobile engines, airplane propellers, or industrial fans. Components in many electronics produce mass amounts of heat that can cause damage if not properly cooled. A central processor (CPU) for example uses a fan and cooling fins to disperse the heat it produces.

With higher computing densities and heavy processing loads, it’s becoming increasingly difficult for air-cooled data centers to keep up with demand. High energy costs and water restrictions can also add to the complexity and cost of maintaining an air-cooled system, resulting in organizations seeking alternative cooling solutions like liquid coolers.

Despite its limitations, air cooling is still the most popular form of CPU cooling for desktops. Air coolers are cheaper than liquid coolers, easier to install and often more efficient than their liquid counterparts. However, they can still be noisy unless near-silent cooling is achieved, and the large heatsink and fan assembly can take up significant space in a computer case, potentially blocking RAM slots or other features. Additionally, an air cooler’s coolant may leak or stop working altogether, requiring a more involved maintenance routine than a simple replacement of a fan. Fortunately, the best air coolers are easy to find at every price point. Our top pick, the Corsair A500, pairs two 120mm fans with a hefty aluminum heatsink that boasts four metal heatpipes to handle CPUs up to 250W TDP while remaining quiet and aesthetically pleasing. air cooling
