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.

Turn Off Computer

Step 1 of course is to turn off your computer, ensuring you have removed its plug from the mains, and then open its case.

Use the Air Compressor

Now into the fun stuff, step 2. Use your air compressor for computer cleaning to clear the interior of the computer of dust. It’s important to keep the torque low and the distance of the dust blower for pc some way away from key components like:

  • 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. Also note that you should not allow the fan’s blades to rotate too quickly if at all, due to their fragility they may chip if spinning fast.

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

Step 4 is focused on removing the dust build-up from the power supply with the dust blower for pc. This step is sometimes to forget about, but it is certainly important. Sometimes the power supply can have a dust filter underneath it, if so, make sure you clean it to your best capability.

Clean the Heatsink

Step 5 is to clean the heatsink, as this is sometimes disregarded, it is as important as the fan on the processor. It is crucial to again, get the dust off the heat sink using a low torque, like with the fan.

If the dust build-up is significantly high, you can take off the heat sink and the fan to complete a better job on the part. Note, do not forget to wipe the thermal grease that is on the heatsink and processor. After wiping the thermal grease, apply some new before connecting the heat sink bank to the processor.

Clean the Ports

Finally, step 6. Here you should use the air compressor for computer dust to clean all the ports on the PC. You can again use the rubbing alcohol and a cotton swab to wipe down any external vents.

Now that these 6 steps are completed, your computer is back ready for daily use, and most importantly, dust-free!

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.

Otherwise, you risk serious damage being done to components. Damage such as chips, bending, and bearing damage on the fans is possible.

How do I clean my computer without compressed air?

There are multiple possibilities, not necessarily good ones, however. It is recommended to use an air compressor if possible, to avoid damaging your computer. Some possible methods include: taking out the heatsink and cleaning it with a brush, using a silicone blower as a cheaper alternative, using your vacuum cleaner, and reversing it to act as a blower, use a hair dryer.

Probably the best alternative is described in the step guide presented in this article… using a cotton swab and rubbing alcohol to clean as much as you can.

How often should I clean my PC?
