Frequently asked questions (FAQs)

We've answered some of the most commonly asked questions to help your search.

Should I buy compressed air to clean my PC?

In our humble opinion, we'd say that compressed air can be used to clean your PC by forcibly removing any dust and dirt in a flash. For a low cost, canned air is quite the versatile option and should allow you to clean most, if not all of your PC in one sitting, which is rather useful.

Is compressed air good for PC cleaning?

In our humble opinion, compressed air is rather good for PC cleaning, offering you a quick and convenient solution for removing any dust or lint buildup inside your computer’s case.

Compressed air cans spray with a pressure of about 145 Psi, so they easily have enough force to provide a deep clean.

In addition, with the extra straw attachments that some canisters have, they should allow you to clean your entire case in easy and hard-to-access places.

How frequently should you clean your PC?

As a general rule, we’d say to clean your PC every couple of months, just to keep on top of things, and to ensure that not too much dust or unwanted debris builds up over time.

Does cleaning your PC improve performance?

In a roundabout way, yes. Whilst cleaning your PC may not appear to help performance, it can keep things running efficiently if no dust gets in the way of fans spinning at full tilt, for instance. 

PC cleaning is more of an act of maintenance than specifically improving performance, but keeping things running as efficiently as possible is likely to improve performance as your PC should be kept running.

Does dust slow down a PC?

In short, it could. If dust is left to build up inside your PC, then it can physically slow down things as fans, which could then limit airflow into your PC.

In turn, this could raise the temperature of key components as they are not being cooled properly, which would then cause the CPU to throttle for instance and its performance to be inhibited by those high temperatures.

Will cleaning a PC increase FPS?

Unfortunately, no, not unless components have been running particularly warm. Cleaning your PC can help cooling performance if the dust buildup has got so bad that it's stopping fans from spinning at the speed they should be, which in turn causes components to not be cooled properly.

Is all compressed air the same?

No, some compressed air is unsuitable for use on circuitry like a motherboard, because of added chemicals like bitterants for example, which discourage inhalation.

Can you clean a motherboard with compressed air?

In short, yes, but not as the only means of cleaning. Compressed air can be blown across your motherboard as a first pass of sorts to remove dust build-up.

For the best results, you'll want to use compressed air in conjunction with a soft bristle brush to remove dust buildup. Use the compressed air for general removal, while the soft bristle brush can be used for finer applications.

Should you shake compressed air?

In short, no. Compressed air should not be shaken, or even tiled, as it may result in liquid being propelled as opposed to vapor. This could result in improper cleaning or a risk of the liquid coming into contact with the eyes or skin.
