How to Increase Airflow in PC case? (Steps, Guides)

Creating a more efficient airflow in your computer case is not as difficult as it may seem, and you only need to follow a few guidelines to do it. In the following article, I will cover some of the most important tips on how to Increase airflow in PC case inside.

A computer case is a closed environment that can get very hot, especially if you’re running a lot of games or heavy programs on the PC.

Your CPU, GPU and motherboard all generate heat that needs to escape from your computer case. You can help this process along by using a few different strategies to increase airflow in your PC case.

How to Increase Airflow in PC case?

Increasing airflow in PC cases is important to get the best performance of the components. This Could be done easily by following these simple steps, so let’s take a look at them.

  1. Make sure the side panels are not obstructed by cables, power supplies, or other objects.
  2. Create a fresh air intake. You can do this by getting a few fans and placing them near the front of the Cabinet which will let cold air in.
  3. Clean out any old dust from inside your PC with a vacuum cleaner and compressed air.
  4. Make sure you have enough fans inside your PC – not too many but not too few either.
  5. Make sure that all of your fans are pointed in the right direction so they can move air throughout your entire system properly.

How important is airflow in a PC case?

Airflow helps in cooling the components running in the PC. Because overheating causes low performance, it is very important to keep the PC cool at all times.

Also, when you are playing performance-demanding games or editing, airflow ensures seamless working of the PC.

Without proper airflow, your PC components may lose their life and wear out sooner. That is why it is very important to keep up the airflow.

Should I open my PC case for Airflow?

There is no absolute need for the PC case to be open for good airflow. Keeping the case open will have a better airflow but it is not necessary.

The main reason to avoid this is to keep the dust from piling up. When the case is wide open, more dust particles tend to settle inside the PC.

This will force you to clean the case frequently. If you use proper fan position, ventilation and speed, you don’t have to keep the case open all the time.

How Distinct Fans helps?

You can use distinct fans for the case to increase airflow. Some cases come with ventilation which helps in better airflow along with case fans.

Even if you have both, you must periodically clean the dust away in the PC case. Because environmental dust can block airflow.

Are fans enough to cool a PC?

Fans are more than enough to cool a PC. Even if you play highly demanding games or render an intense video, fans are sufficient to provide the necessary cooling.

Only the number of fans may differ according to the usage. If you are a light user, a normal fan with a low power setting will be enough.

If you are a heavy user, then you may need more than one fan and at proper ventilating points.

How can I increase my PC fan speed?

Fan speed can be increased from the BIOS settings page. It is important that you have your BIOS updated first.

  • Restart the PC, after Power-on Self-test, you can enter the BIOS page.
  • There you can change the fan speed settings from automatic to manual and increase or decrease the speed.
  • The settings may vary slightly but they can be easily inferences from the BIOS page.

What are the Types of PC case Fans?

Air is drawn into the case by a fan and then, as it goes through the system, it cools the components and is eventually expelled out an exhaust fan.

A chassis has a number of fans, each of which serves a specific purpose:

Intake Fan

The intake fan absorbs air from outside and blows it into the case. Internal components need cooling to operate properly.

Exhaust Fan

The exhaust fan expels heat from inside the chassis. Air from inside the case is circulated through heat sinks to remove heat from CPU, GPU, motherboard chipset, RAM modules and other high-temperature hardware.

Front I/O Fan

The front I/O (Input/Output) fan blows air over or around USB ports and audio connections on a computer tower.


Increasing the airflow is very important to have a long life for the PC. It helps in keeping the components cool.

Proper ventilation and fan positioning are important to keep away unwanted dust particles inside the case. Keep the case dust-free to have good airflow and cooling.
