How to improve airflow on your gaming PC

Optimizing your computer’s airflow is very important if you don’t want these overheating warnings or want to avoid serious damage to your computer’s internal hardware.

Building a computer today is very easy; You can get a set of modular parts, buy a case and assemble them together. However, when you are playing these resource-intensive games, know that they negatively affect your PC.

Gaming PCs often push the boundaries to provide a smooth gaming experience, often resulting in the GPU overclocking, thus generating more heat. It is important to improve air flow.

Without getting into physics or thermodynamics, here’s a step-by-step guide to properly optimizing airflow.

Get the right fans for your PC


Fans in gaming PC

Cooling fans are available from a number of different brands, and there are many options available to you. First, you need to determine which fans are compatible with the fan mounts. Depending on the size of the shell, you will have four different options:

However, pregnant women are not the only thing you need to think about. For example, the size of the fans is also an important factor. Larger fans tend to move the same amount of air as smaller fans, albeit at lower cycles.

As a result, larger fans are generally quieter than smaller fans. Another thing to consider is the type of fin. There are two options: one that provides better constant pressure, and the other that is optimized for airflow.

The latter is generally quieter and is ideal for mounting to the front of the case. The first pulls in or pushes air through using extra force, so it’s a better option if you’re going to be mounting fans to the back of the case. And then you also have to consider if you want RGB and aesthetics.

Chart your computer fan flow direction

Once you have purchased fans for your gaming PC, it is time to learn how to optimize the airflow and plan it properly. There are several important things to consider, starting with the direction.

Remember that air always flows from the open side, moving in the direction of the protective fan grille. Simply put, air should always flow from the front towards the back. Thus, ideally, the open side of the fan should always be outside the housing. These are also known as draft fans.

Most computer bags are designed to allow air flow from front to back and from bottom to top. Therefore, since the open side sucks in air, you can also place it in the back facing inward or upwards, if your condition permits.

Keep the computer in a well-ventilated area

This one goes without saying, but it’s something that many people tend to ignore a lot. Your PC needs to be kept in a well-ventilated area, but not somewhere where it will be sitting among drafts.

Some fans, especially air intake fans, are important to direct cool air from the surroundings into the enclosure. Fans in the back usually act as exhaust fans, blowing hot air out of the system.

Thus, if you put your computer in the corner or in a closet somewhere, it will not help you at all. It will simply continue to circulate the same hot air around it, eventually causing the internal parts to overheat.

Ideally, you might want to keep your computer a little elevated, especially if the floor is carpeted. Or you can always keep it on a desk or table if you prefer.

Get the obstacles out of the way

Proper cable management is essential to improving the airflow in your computer. Ideally, you would want to have as few obstructions as possible between the exhaust fans and the intake fans to allow efficient airflow, but this is not possible.

So, it is important to start from the front. Remove any obstructions in front of the intake fans so that you can draw air cleanly. Then go inside. Ensure that all internal components, such as GPUs or hard drives, are installed horizontally.

Once that’s done, the next step is cabling. Ideally, you might want to use some zip ties to bundle up the cables and move them out of the way. In some cases, there may be additional power cables, so be sure to move them to one side.

If your case has any spacers, use them to allow more unobstructed airflow inside. And if you really want to make things better, ditch those bulky hard drives and switch to slimmer, slimmer SSDs instead.

Adjust computer fan control speeds

Now that you have the fans installed and the internal components properly adjusted, it is important to configure the fan control speeds.

In general, most BIOS programs allow you to quickly adjust the fan speed. There are temperature sensors inside, so you can determine when the fans should run at full speed.

There are third-party apps, like SpeedFan, that you can use to adjust speeds as well. Or, if you want, you can also get a fan controller. Some fans also allow you to set up configurable profiles!

Balance the air pressure inside your computer

Balancing the indoor air pressure is very important. Because there are different components inside the enclosure, balancing actual equal air pressure is simply not possible.

Here, you have two options: negative or positive air pressure. The latter simply means that your gaming PC is drawing in more air than it is being blown out, and vice versa. Try to keep the balance, or as close to it as possible, to reduce dust buildup and keep your gaming PC cool.

The airflow on your PC is now improved

Now your computer should stay cool, thanks to a nice and perfect airflow. However, no matter how well you protect your computer from overheating, dust will still find its way in. This is even more important if you live in a dusty environment. At least once a week, you need to remove the cover and clean the inside.
