How to Clean PC With Air Compressor

For computers to operate successfully, they must not overheat. Heat to them can be very damaging, they don’t like it. Dust is very common in every household, and if it was to build up inside a computer, the cooling components of the computer could be sabotaged. This will then cause the computer to overheat, reducing the life span of itself and its components.

To avoid this life span reduction, and allow your computer to function correctly, it is advised that you clean the interior of your computer every 6 to 12 months. You may now ask, but how do I clean my PC with an air compressor? Well, this step-by-step guide should provide you with enough help to successfully do that.

  • motherboard
  • processor
  • memory and expansion cards

Use the air compressor for computer dust cleaner to get rid of all the dust build-up on the fans of the case. It’s important to place your finger on the fan when blowing at it to stop the fan from rotating. This allows the dust to be freed.

Use Rubbing Alcohol

Step 3 incorporates using rubbing alcohol and the aid of a cotton swab to wipe the blades. If you struggle to clean them properly, you can take them off the case to do a better job.

Get Rid of the Dust

Benefits of Using a PC Air Compressor

As mentioned, using an air compressor to clean your PC and computer can help protect its components from overheating. This overheating is a very non-desirable issue. Preventing it, can certainly boost your computer’s lifespan, no brainer right?

Using an air compressor to clean your computer instead of other methods can guarantee the safety of expensive components of the pc. Any small errors with some components can result in significant costs. Costs you certainly don’t want to have to face, so, clean your computer properly with an air compressor!

You must be very careful in the cleaning process of a computer. Most people would quickly turn to something handy, for instance, cloth. Using a cloth to clean your pc can cause numerous scratches on components that are delicate like the motherboard. These little scratches can lead to bigger scratches, and make the device fail at some point in the long run.

People think cotton or cloth can get to the very small spaces or holes in the device, but so can an air compressor? If anything, it will do a far better job. Not only does it protect your computer from scratches but it also will be done A LOT quicker, meaning you can move on and focus on other issues.

Another key benefit would be that the air compressor can be used to clean other components that aren’t too easy to get to otherwise. For instance, components like graphics or sounds cards.

How Much PSI do I Need to Clean my Computer?

This is equally as important as the torque setting on the air compressor. Applying too high a PSI when cleaning your computer could potentially cause a significant amount of damage to it and its components. You must be delicate when blowing the fans as they can chip easily if sped up too fast.

It is therefore recommended that you do no exceed 125PSI when removing the dust from your pc. This is a sufficient amount to clear the dust without causing any unnecessary damage. Most home and shop compressors will produce about 125 PSI because the majority of air tools like to work on pressure between 90 and 125 PSI.

175 PSI is also very commonly found in home and shop compressors, but this causes air tools to destroy themselves sooner rather than later due to excess pressure. Therefore, it is recommended to avoid 175 PSI air compressors.

When using your 125 PSI air compressor to clean your computer, it is vital to remain a suitable distance away from the device, say, around 6-8 inches. This will help reduce the likelihood of damage occurring.

Is it Safe to Use an Air Compressor to Clean a Computer?

A simple answer to these questions, yes. It is certainly safe to use an air compressor to clean a computer, you just need to be wary of the amount of torque the air compressor is set to. It is important to keep this torque value low. Another important consideration is the distance at which you’re using the air compressor from the PC. Do not use it too close to the computer, and do not allow the fan’s blades to aggressively rotate from the force of the air compressor dust blower.

Can I clean my PC with air?

Yes. By now you should be able to answer this question! Air is certainly an extremely suitable choice for cleaning your PC. In fact, it’s probably a better option than anything else you have considered up to this point.

Some people prefer to use canned air, as they believe it is safer than compressed air. Both are as effective and safe as the other, as long as you correctly use them.
