A Comprehensive Guide to clean your CPU fan in 2022

A CPU fan is an essential component of any computer, as it helps to keep the internal components cool and running smoothly. However, over time, dust and dirt can build up on the fan blades, which can eventually lead to problems. In this article, we’ll show you how to clean your CPU fan so that it’s running efficiently.

What is a CPU fan?

A CPU fan is a cooling fan designed to keep your computer’s CPU cool. The CPU, or central processing unit, is the brain of your computer, and it can get very hot when it’s working hard. A CPU fan helps to regulate the temperature of your CPU by blowing air over it and keeping it cool.

If your CPU fan isn’t working properly, or if it gets dirty, it can cause your CPU to overheat and shut down. That’s why it’s important to clean your CPU fan regularly.

Why do you need to clean a CPU fan?

A CPU fan is one of the most important parts of a computer, as it helps to keep the CPU cool and prevent it from overheating. Over time, dust and other debris can build up on the fan blades, causing the fan to work less efficiently. This can lead to the CPU overheating, which can damage the computer. Therefore, it is important to clean the CPU fan regularly to ensure that it is working properly.

How to clean a CPU fan from Desktop Computer? [Step-By-Step Process]

Assuming you have a desktop computer, the first thing you’ll need to do is unplug the power cord from the back of the CPU. Next, remove the CPU’s case by unscrewing the screws that hold it in place. Once the case is off, locate the CPU fan and gently remove it from the CPU.

Now that you have access to the fan, it’s time to start cleaning it. The best way to clean a CPU fan is with compressed air. You can also use a vacuum cleaner with a brush attachment to remove any dust that’s clinging to the fan blades. If you’re using compressed air, make sure to hold the can upright so that you don’t blow dust into other parts of the CPU.

Once you’ve removed all the dust from the fan, reattach it to the CPU and screw it back into place. Put the CPU case back on and screw it shut. Finally, reconnect the power cord and turn on your computer.

How to clean a CPU fan from Laptop? [Step-By-Step Process]

Cleaning a CPU fan on a laptop is a bit more difficult than doing so on a desktop computer. This is because most laptops do not have removable case covers. As such, you’ll need to be careful when cleaning the fan so that you don’t damage any delicate parts of the laptop.

To clean the CPU fan on a laptop, start by unplugging the power cord and removing the battery. Next, flip the laptop over and locate the vents on the bottom of the device. Using a can of compressed air, blow all of the dust out of the vents. Be sure to hold the can upright so that you don’t blow dust into other parts of the laptop.

Once you’ve cleared all of the dust from the vents, reattach the battery and power cord. Turn on your laptop and check that the fan is running properly. If not, you may need to take it to a professional for further diagnosis.

What products to use when cleaning a CPU fan?

There are a few different products that can be used when cleaning a CPU fan. Some people prefer to use compressed air, while others may prefer to use a vacuum cleaner. There are also specialty cleaning products available that are specifically designed for cleaning CPU fans. Whichever method you choose, make sure that you follow the manufacturer’s instructions carefully in order to avoid damaging the fan.

Pros and Cons of cleaning CPU fans:

Cleaning a CPU fan can be a great way to keep your computer running smoothly and prevent overheating. However, there are some pros and cons to consider before you decide to clean your CPU fan.


  • Cleaning your CPU fan can help prevent overheating and improve overall performance.
  • It can also help prolong the life of your CPU by preventing dust and dirt buildup.


  • Cleaning your CPU fan can be a bit tricky, so you’ll need to be careful not to damage any sensitive parts.
  • You’ll also need to make sure that you’re using the right cleaners and tools, as using the wrong ones could damage your CPU fan.

Does cleaning CPU fan increase performance?

It depends on the quality of the fan and how much dust and dirt is clogging it up. If it’s a cheap, low-quality fan, then cleaning it might help a little bit. But if it’s a high-quality fan that’s clogged with dust and dirt, then cleaning it could actually damage the fan or cause it to overheat. In general, We would recommend just buying a new fan if the old one is clogged up with dust and dirt.

How often should you clean your CPU fan?

Dust and other contaminants can build up on the fan over time, which can cause it to run slower and hotter. Fan cleaning should be done every few months or so, depending on how dirty the environment is.

Does dust drop FPS?

Yes, dust can definitely drop your FPS! If you’re not careful, it can get into your system and start clogging up your fan and other components. Over time, this can lead to a significant drop in FPS. So it’s definitely something to be aware of and take measures to prevent.

Can dust make PC run slower?

Dust can make your PC run slower for a few reasons.

First, dust can accumulate on the components inside your computer case, causing them to overheat. Your computer’s internal fans might not be able to keep up with the dust buildup, and eventually, your system will overheat and shut down.

Additionally, dust can block airflow and prevent cool air from getting to your components. This reduced airflow can also contribute to overheating. In addition to causing your PC to overheat, dust can also cause hardware failures.

Dust can build up on circuit boards and other sensitive components, causing shorts and other problems. Eventually, this dusty buildup can render a component completely unusable. 

How do you clean a CPU fan without removing it?

You can clean a CPU fan without removing it by using compressed air to blow the dust and debris out of the fan blades.

You can also use a Vacuum cleaner with the brush attachment to lightly brush the blades to remove any build-up. If you have really stubborn dirt and grime, you can carefully remove the fan blades and wash them in soapy water.

Allow draining them thoroughly before putting them back on and turning on your computer. Do not use any cleaning solutions directly on or near your electronics as this could damage them.

Why cleaning the CPU fan exhaust is important?

Cleaning the CPU fan exhaust is important because it prevents the accumulation of dust and debris inside the computer. This dust and debris can cause overheating and damage to the hardware. By cleaning the CPU fan exhaust, you can help keep your computer running smoothly and efficiently.

Does dust affect Ping?

Dust can affect Ping because it can cause the ball to travel in a different direction than intended. When dust accumulates on the ball, it creates more friction and resistance between the ball and the clubface.

This can send the ball off course or alter its trajectory. In some cases, it may also cause the ball to spin less than desired, which could lead to a decrease in distance.

For these reasons, it’s important to clean your clubs and balls regularly to minimize dust build-up and ensure consistent results.

Can dust cause high CPU usage?

There are a few things that could cause high CPU usage from dust, but it’s not likely the primary issue.

For one, if there’s a lot of dust build-up on your computer’s components, it can interfere with heat dissipation and cause your system to run hotter than it should. This can lead to throttling, which reduces performance to prevent damage.

Additionally, if dust is blocking fans or other airflow channels, that also impedes proper cooling. However, bear in mind that most modern computers have ways to deal with dust buildup; for example, many laptops have self-cleaning fans that automatically spin in reverse every so often to expel dust.


Cleaning your CPU fan is a simple and effective way to keep your computer running smoothly.

By following the steps outlined in this article, you can easily remove dust and debris from your fan, preventing it from overworking and potentially damaging your computer.

With just a few minutes of effort, you can prolong the life of your computer and keep it running at peak performance.
