The Basics of Computer Case Fans

To start with, you should ideally be able to choose the case fan that best fits your criteria. Perhaps you would prefer a fan with less noise? A model that fits your certain budget? Maybe a certain size such as 120mm or 140mm or are you looking for something flashier for gaming or style like an RGB case fan?

Once you have established what type of fan you are after, you can narrow the search criteria further by using customer reviews and comments from Amazon. It’s not very difficult to find great case fans quickly by using this method. However, it’s important to consider the brand name of the fan and the warranty offered along with it. The products should also have an excellent customer support system.

Usually where the user can take up any queries, complaints and have access to after sale services for any regular maintenance required. All of the case fans reviewed above have these services built into their business. You can find the best of all of these fields in the detailed reviews and the table above. All the way from the best case fans this year, to specifics like the 120mm, 140mm and RGB LED fans.

Where are the Fans Located?

A personal computer (PC) fan is located on the inside or is attached to the computer casing. They are used to provide cool air inside the computers from the outside. This works by drawing in nearby cool air from one side of the base unit and expelling it out of another, to create a tunnel of optimal airflow.

Most equipment and devices inside of the computer, like the central processing units, graphics card, RAM and other components use up a lot of power. Which leads to a very high amount of heat being produced. In order to prevent the overheating of the core components, fans should be installed and maintained to prevent malfunction, instability or any serious damage to the PC system components.

Overheating your PC on a consistent basis can have a hugely adverse effect on the overall lifespan of core components inside of the computer. A desktop case fan is needed for the proper functioning of the PC, else it will start to slow down all tasks on the computer and may even cause the computer to blue screen (BSOD), this is especially likely during any hardcore gaming or heavy software/ programs.

Types of Cooling Fans for a PC

There are two key areas that fans should be on a PC. Firstly, you will need an excellent quality fan for the CPU itself in order to provide an ample amount of air to the system that generates the most heat. The second type is in the topic of this article, the case fan. The size and the voltage of fans themselves are highly important, as well as the fan noise output from the cooling fans which could get quite loud.

When choosing the best case fans, it is important to remember these factors. RGB refers to a method of creating color. It stands for Red, Green, and Blue. This is sometimes used to describe the display on a monitor. It’s the computer’s color space which helps to display and capture all images electronically.

There are many RGB lighting kit available with great LED effects and even greater appearance. Above is a list of the top four case fans that we have reviewed. All of the fans chosen for this year are based on their design, performance, cooling efficiency, build quality and most importantly, value for money.
