What is computer case

Computer case is the most commonly used device to protect your computer from external physical damage. A computer case is made up of different materials and can be made of plastic, metal, wood, or some other material. The computer case is the part of the computer that houses all the components such as motherboard, power supply, hard drive, optical drive, fans and so on. All these components are placed in a protective shell called case in order to keep them away from dust particles and prevent them from getting damaged by static discharge.

A good quality computer case not only protects the components inside but also makes the overall appearance neat. It is quite important for you to choose a good quality computer case because it will last longer than low-quality cases. You should always buy high-quality computer case if you want long term protection for your computer.

A computer case, also known as a computer chassis, tower, system unit, or cabinet, is the enclosure that contains most of the components of a personal computer.

Type of Computer Case

There are two main types of computer cases: Desktop computer cases and tower cases. Both have their own advantages and disadvantages.

  • Desktop Computers Cases : In this type of computer case there are few components like CPU, video card, keyboard, mouse and monitor. This design is usually seen with Windows Operating System.
  • Tower Cases : Tower computers are more expensive compared to desktop PCs as they have more components inside. These cases come with higher capacity which means more internal storage. They have larger size LCD monitors and can house many components at once. Most people use tower cases when they need large number of ports like USB 3.0, HDMI etc.

Both these types of computer cases are very essential for any user who needs a lot of space to store his/her components. You can find both types of case for laptops as well as desktops. There is nothing wrong with buying either one depending upon what you want.

How Are Computer Case Fans Measured

Generally, the size of the fan you need is dictated by the size of the fan fitting location in your computer case. The sizes of all the fans on our website are given in terms of the distance between the fan’s screw holes, NOT the distance between the fan’s four sides! The 120mm fan is the most common size, followed by the 80mm. This is not so much determined by client choice as it is by modern PC case designs.

Regarding the fan’s thickness (depth), 25mm (1 inch) is by far the most common depth, while smaller fans may have depths as little as 15mm or even 10mm. Unless otherwise specified, all of our fans are 25mm thick. If you have any queries regarding which fan to purchase, please contact us.

What Is Computer Fan?

Fans are small mechanical devices that make sure your PC stays cool. When air flow does not reach certain parts of the system, heat builds up quickly, damaging electronic circuits. Modern computer systems include fans to provide cooling airflow through the interior of a computer chassis.

Fans draw warm air out of the computer via a fan duct and blow it across the fins of the heat sink where it then flows into the outer part of the enclosure. As the heated fluid passes over the fins, heat is transferred to the surrounding cooler air. This process increases the temperature differential between the hot and cold parts of the system.
