The compressed air from the compressor is great because, at this time, you have understood air is the only and best choice to clean the unit internally.

Is it Safe to Clean out a Computer with an Air Compressor?

Yes, using an air compressor for cleaning a computer is complete and does not cause any damage. You only need to be careful about the torque, PSI, and distance, and low torque is recommended from a specific distance to ensure no damage to components.

In addition, try to be gentle while cleaning the dust particles and ensure the fans do not move aggressively because of the force of the compressor.

How to Clean my PC Using an Air Compressor?

To ensure your computer works successfully, you must be careful about overheating. Overheating can occur because of nonstop working or dust in the PC, which leads to more running.

Dust accumulates in the computer because dust is common in our household. But when it gets accumulated in the computer, it sabotages the components which cool down the computer and ends up reducing the life of the pc

To avoid this, you need to clean your computer every 5-6 months but do you have to take your computer to professionals, or can you do this at home? The below steps will help you learn the cleaning process of your computer using an air compressor at home!!

1. Turn Off Your Computer

The very first your need to do is to shut off your computer. Never try to do anything with your pc while it’s still running. Switch it off/ unplug the cords both from the outlet and unit. After this, wait for a while to let it cool down, then open the case of the computer. That is the area where you need to use compressed air.

2. Clean with Air Compressor Using Measure

Use your compressed air compressor to blow dust out of the computer’s interior to clean it from dust. It can easily be cleaned with compressed air even from a distance: all the dust gets removed due to the forces involved. However, you should keep the compressor at a specific distance from the components.

You now only need to keep the compressor at a distance but also have to keep its torque low. The parts are the motherboard, processor, and memory/expansion cards. Use compressed air on them, but from a distance: and at low torque because they can cause static.

Dust gets buildup on the fans of the case place your finger to stop it from rotating while cleaning. Also, do not get surprised if there is a decent amount of dust!!.

3. Use of Alcohol

Once the dust particles have been removed with the compressor, use a cotton swab and rubbing alcohol to wipe the unit’s blades. ( you can take them out and then clean them if you feel trouble cleaning). Alcohol will help in cleaning properly without damage.

4. Removing dust from the Power Supply

Then, remove dust accumulated from the power supply. Do not forget this step because sometimes the power supply has dust accumulated. Otherwise, it will cause damage to the fans, compressor and sound cards of the computer.

That is also important because it has a motherboard nearby, and not cleaning it causes the dust particles to build up there, resulting in short circuits or other issues.

5. Heatsink Cleaning

Next is to clean the heat sink, using a low torque clean the dust particles. If the accumulated particles are high, remove the fan and the heat sink, then clean it ( for better cleaning.)

There is thermal grease on the heatsink and the processor: ensure to wipe it and apply more before connecting it back to the processor.

Then clean the heatsink ( fan), which is important for the processor. Use a nozzle attachment to get all the dust buildup removed. That will help you protect friction in the unit.

6. Clean the All the Ports

Lastly, use your compressor’s compressed air to clean the ports. You can also use alcohol to rub and wipe the particles. After these steps, your computer is ready to be used without having any dust on it.

What are the Pros and Cons of Using an Air compressor for Cleaning a PC?

1. Prevents Overheating

Air compressors play a great role in preventing components of the unit. The compressed air from the compressor easily cleans the dust particles from the compressor, which prevents the system from overheating and results in damage control and a longer lifespan.

2. Safety of components

Using an air compressor provides safety to the parts of the compressors. How? Because it cleans the components without the need to touch them. For example, if you use any cotton or cloth, it will leave scratches. And any small scratch can ruin your computer.

3. Quick – Saves time

Using an air compressor saves time; how? Because it quickly and easily cleans the dust particles without the need to waste your time for a long time. That is why it is a time-saving method.

4. Cleans Not Reachable Parts

Air compressor will help you reach those parts where you cannot reach. It can clean the hidden parts of sockets that are required for the functioning of the compressor, sound cards, and graphic cards. The cloth might reach the tiny hollows and spaces, but the nozzles of the compressor are much easier.

5. High Pressure can Cause Damage

The only disadvantage of using compressed air is it can damage the sockets or other components of the compressor if you do not use it carefully. High torque or PSI can aggressively work and damage the tiny components of the unit.

Can Compressed Air Damage a Computer?

Compressed air can damage your computer, but it only happens when you do not take precautions and are not gentle. Consider these things to prevent damage.

How Much PSI Do I Need to Clean My Computer?

How much PSI will be used from cleaning the computer is as important as the low torque setting. If you clean with high torque, it will cause damage same goes for PSI. the high PSI can lead to components damage in the unit.

While blowing the fans of the unit, be careful. They can chip on the fast speed. That is why it is great to use compressed air, which does not exceed 125 PSI. That can easily clean the dust particles without damaging anything.

Most compressors ( home and small) have 90-120 great PSI. Remain at a suitable distance while cleaning from the unit (5-6/6-7 inches). Do not exceed this limit!!

What about CFM?

Depending on the amount of time or period you need your compressor. If you are professional, then you need a higher CFM compressor. Otherwise, you can use a 4-5 CFM compressor for general use, and it only ensures the airflow rate.

Tank Size

It does not matter that much because tank size only stores air, so it will be help full for your while working. Alternatively, you can use a high-capacity tank if you have one, but use less torque and PSI to prevent damage.

How do you clean computer and laptop fans with compressed air?


  • Turn off the computer and unplug all the cords and wires.
  • Dust away the interior particles from the CPU.
  • Then put a pencil or pen or your finger to keep the fans still and remove the particles.
  • Clean the blades of the fan with a cotton
  • Clean the surroundings, and your job is done!!


Air is probably the best thing you can use because you can blow out the dirt without having to touch components with your bare hands. In the long run, an air duster with an appropriate mini air compressor ensures that your computer runs smoothly for many years.
