Why Is My PC So Loud?

Why Is My Pc So Loud 1

Computers are powerful machines, but this does not mean that they are loud in any way. They are packed with multiple fans that keep them cool, but these fans don’t create a lot of noise. But if your PC has been making a lot of noise lately, something is wrong. Therefore, to help you out, we will discuss why your PC is so loud and how you can fix it.

Quick Answer

The biggest reason why your PC is so loud is dust. This is because dust can make your PC fans spin faster, which makes them noisy. Another reason why the fans could be spinning faster is viruses

Every PC component is vital in keeping the system up and running. If you take a single component out of your PC, it might not even turn on. As for fans, they are extremely important as they help keep the system cool. Without them, your PC will overheat, and you won’t be able to use it for long.

Why Your PC Is Loud?

Now, while fans are meant to be silent and not something that will disturb you while working, there can be times when they start creating a lot of noise. Fans usually become noisy when they start spinning faster than before, and there are multiple reasons why it could happen. Therefore, it is important to learn about them so you can quickly solve the problem and get back to work.


If you own a PC, dust is your biggest enemy. Even if you think that your PC won’t get dirty, dust will make its way inside it one way or another. This is why cleaning the PC every two or three weeks is extremely important. If you don’t, then a lot of dust will get stored in your PC, and for those who don’t know, this can cause heating issues.

When there is a lot of dust, the fans need to work harder than before to keep your PC cool. In other words, they will start spinning faster, resulting in more noise. Therefore, if you haven’t cleaned your PC lately and it is making a lot of noise, now is the right time to get it done. 

Poor Ventilation

By keeping your PC clean, we don’t mean that you cover it with a piece of cloth and block all the ways from where dust can get inside it. While this will stop your PC from getting dusty, it will worsen things. This is because there should be enough space around your PC for air to circulate, as your PC can start overheating otherwise. 

For instance, if you place the back of the PC too close to the wall, there won’t be much space left for the back fan to throw out the hot air. This will cause your PC to overheat, and your fans will start working harder. Which, again, will result in more noise. 

Thermal Paste Issues

Many people don’t know they need to use thermal paste to keep the CPU and GPU cool. These two components generate the most amount of heat, and thermal paste is something that keeps them cool. But a big mistake many PC users make is forgetting to change the thermal paste after a few months. This results in the CPU and GPU overheating, thus building more hot air inside the PC. 

To prevent this from happening, you need to take your PC to a shop and get the thermal paste replaced. You can even do it yourself, as the process isn’t difficult, and you can find hundreds of videos on YouTube that can teach you how to do it. But if you think you might end up damaging the components, it will be better to take them to a shop and let experts take care of them for you. 


Viruses are the worst thing that can happen to your PC. These viruses come in different shapes and sizes and have only one purpose: to ruin your day. Now, these viruses end up using a lot of your PC’s resources to either steal your data or corrupt the files, increasing the load on the system. And when the load increases, so does the heat. In other words, as you might have guessed already, your fans need to spin faster than normal to prevent your PC from overheating. 

To prevent this problem, you need to download good antivirus software and get rid of all the viruses. The Windows Defender is also an excellent program for this, as it can perform a full scan of your PC and remove all threats. After the threats have been eliminated, you will notice that your PC is quieter than before. 


This was everything you needed to know about why your PC is so loud. As you can see, there are multiple reasons your PC makes a lot of noise. But thankfully, there are ways to solve the problem quickly. Before trying anything, we will suggest you clean your PC as this makes it become quieter 90% of the time. There can also be times when your hard drive creates noise instead of your fans. In this case, you need to take it to the shop as it needs to get repaired.
