How to keep Computer Cabinet cool? (5 Best Ways)

Whether you’re a hardcore gamer or just an average mainstream computer user, your system’s components are always at risk of overheating, especially if you don’t take any measures to ensure temperatures are kept in check.

Your computer contains many parts, all of which generate heat when your computer is on. Some features, like the graphics card and the CPU, can become so hot that it’s possible to fry an egg on them.

While your computer has several fans that manage this heat, sometimes it can’t remove the heat fast enough, risking severe damage to your PC.

Below are three straightforward solutions to keep your computer cool, preventing it from overheating and causing damage.

Allow for airflow

To keep your computer cabinet from overheating, the most simple thing you can do is give it a little breathing room to ensure that air can flow through gaps to your CPU.

This is most easily done by removing obstacles blocking the air from reaching your cabinet. It’s essential to ensure that there is nothing placed next to the sides or the back of your computer as most, if not all, of the hot air is released from the back end of the computer.

When your computer is sitting inside a desk all day with the door closed, cool air cannot enter the cabinet. Meanwhile, hot air is generated within the cabinet, which keeps increasing in temperature as your PC runs.

Thus, it’s crucial to ensure that the door of your CPU is left open while the computer is on so that all the hot air can be released and cool air is allowed into the cabinet.

Using a cabinet cooler

While this method might be a little more expensive, using a cabinet cooler can save you a lot of money in the long run. Adding a cabinet cooler helps exhaust all the hot air your PC generates by using the fans to blast all the hot air out.

Most standard PC cabinets are not well-ventilated; thus, desk manufacturers ask you to leave the door open while your computer is in use. However, if you don’t like how your setup looks with the door open or the door is just inconvenient, adding a cabinet cooler is a great solution.

It also helps keep the air running through your devices clean and contamination-free, meaning less dust will get stuck on your fans. A cabinet cooler also helps keep your devices dry from the humidity and moisture that air naturally contains. 

Make sure to clean your fans often

If you go too long without cleaning your CPU fans, dust will get stuck in your computer fans, causing them to slow down and eventually stop altogether.

One of the most inexpensive and efficient ways to cool your PC is to clean the internal fans. There are usually three fans in your PC. One is on top of the CPU, one inside the power supply, and one in the front.

The best way to clean these fans is to turn off your computer, open up the case, and use canned air to remove all the dirt and dust stuck on each fan.

If you feel as though your computer really is quite dirty, it’s best to take your computer outside and clean it there; otherwise, all that dust will just remain in your room and inevitably end up in your PC all over again. 

Install a liquid cooling system

To effectively cool a computer’s Cabinet, liquid cooling is mostly best to use. All-in-one (AIO) liquid coolers, which are more efficient than air coolers and simple to install, are already available.

Most water cooling systems include the radiator tubes and water block, so there’s no need to source them separately. When fitted, the water block with a cool plate at the bottom rests on the CPU.

It contains water to absorb the heat produced by the CPU. After the water has absorbed the heat, it is pushed via a pipe to a radiator, where it is cooled before being returned to the CPU through another hose. This keeps your computer casings cool as cool.

So, how do you set it up? Most PC cases feature many radiator mounting locations. The radiator is often mounted on the front, top, or bottom of the casing.

To prevent problems, it’s important to select where the radiator will go ahead of time. After deciding where to place the radiator, attach the fans to it using the long screws supplied.

To indicate the direction of the airflow, modern fans frequently contain an arrow or some other form of marker.

Installing Extra Fans

You’ll probably see a 2 to 5 degree drop in temperature if you add an extra pair of fans. Try several fan positions; you could discover that one fan at the top and one at the back constantly produce temperatures that are a few degrees lower than those produced by the two fans at the back.

If you wish to add more fans to your motherboard, you may either choose a Fan Hub, which needs a separate power supply, or a Y splitter, which enables numerous fans to be attached to a single fan header.

Be aware, however, that the majority of headers have a maximum amount of power that they can give, so keep this in mind.

Why Do We Need to Keep Our PC Cabinets Cool? 

As chip manufacturers push boundaries to ensure that their hardware achieves greater speeds, the components must use more energy. As a result of this, the hardware used generates more and more heat than ever before.

As computers function based on the movement of electronic impulses, if the computer chip gets warmer, these electric impulses travel much slower. This can manifest in these impulses not arriving when they are scheduled, causing the computer to compute numbers incorrectly.

An example of this would be 1+1=0. Too many of these, and your computer can even crash. Thus, with the latest evolution in processors and video cards, it’s essential to ensure your computer does not overheat.

Ideally, it would be best if you tried to keep your PC’s temperature around 65-70 degrees Fahrenheit; however, computers can function in environments that may be cooler or hotter than this.

Why Do Computer Cabinets Overheat? 

There are many different reasons why your cabinet overheats. However, the primary and most significant reason why computer cabinets usually overheat is due to poor ventilation.

When there is not enough airflow or any way for the hot air to escape, more and more hot air builds up within your cabinet, causing it to overheat. Another reason why your computer cabinet might be overheating is that your CPU may not have a sufficient amount of fans.

Computers that have a mid-tower or more extensive case require three fans minimum; however, ideally, you should have at least five fans, as that’ll prevent your CPU cabinet from overheating.

If this is not the reason, chances are your fans might not be configured correctly, as they might be working against each other.


Thus, it’s quite necessary to ensure your computer cabinet does not overheat since that means your computer will also overheat, which we definitely want to avoid.

There are many reasons why your computer could overheat, and the most essential step is figuring out the cause. With the solutions provided above, this should not only use less power but also help your system run faster and more efficiently once it starts running cooler.

Don’t be afraid to run tests to help you get to the bottom of the problem, as the issue might not always be obvious. We hope this article helped solve any of your queries and conveyed just how important cooling your system is.
