Whether it is your cooling fan or the intricate parts that get blocked. It is worse when the cooler in your CPU is unable to dissipate heat quickly because of the accumulating dust in its parts.

We all know what happens when the cooler does not work as efficiently or stops working. The electronic device begins to overheat, which is not a good experience. Connected to this, once the device gets heated up, it begins to work slowly and lags. On the other hand, using a liquid cooling system is quite the best and most efficient way to cool your CPU.

How To Clean A CPU Cooler?

As understood by now, or by personal experience, if your CPU’s cooling system gets clogged up, your entire working system will become inconvenient. This might even cause you to spend a fortune later, by cleaning it professionally or getting it completely changed.

The first thing that you must do before going on to clean is to take safety measures.

Switch off all electrical outlets connected to your CPU to prevent any electrocution. Always wear your protective gear and keep your tools at hand. When you are moving on to open the CPU, do so in a clean and dry place. Finally, make sure that the cooling fan is not spinning, to prevent any drastic injuries to yourself or those around you.

There are two ways by which you can choose to clean- dry and wet.

Let’s discuss the dry cleaning first.

1. Canned Compressed Air

It is always recommended that your CPU should be cleaned using canned compressed air at first. This is especially helpful in cleaning the small electronic components that are present in your CPU. As the air is static-free, it helps in preventing any damage to the surrounding parts. I would say that it is the safest and most inexpensive method by which you can easily get your CPU as new as before.

You must make sure that the air is at a limited pressure because if force is applied, it could cause some wires or parts to tear or break. When you use the canned compression air method, you will see that a considerable amount of dust, if not all, has already vanished.

Using this method is extremely economical as well. You will get your smooth working and efficient cooling fan quickly.

2. Using a Vacuum

Another method that includes the usage of air is of vacuuming. If you have a small, compact vacuum cleaner at home, it will readily do the same job as an expensive one. But, if you wish and are not on a budget, you can also purchase a small electronic duster or else. It is recommended that you do not use any vacuum cleaner that plugs itself into the wall to work, as it may create electrostatic particles.

Still, if you wish to use an electronic cleaner, it is no issue. You can take the cooling fan out of the CPU and then clean it. This way, it does not produce any damage to your CPU or even to the other electronic parts.

Now, coming to cleaning the CPU using a damp fabric.

Sometimes, the placement of the cooler concerning other parts makes it suitable that you use a damp fabric. Such fabrics are suggestive to be cotton or something that will be easy to wipe with. Make sure that your fan is not connected to the CPU to be able to cool much easier and to prevent you from facing any electric shocks.

Initially, you must dust off the CPU cooler and then go on to wipe it clean. Although this is an easy and economic method, it does have some risks. You must try not to touch any of the surrounding tables or parts, given their fragility. If you do so, you may end up damaging their working system with the water. Alternatively, you can switch to using cotton pads or swabs dipped in isopropyl alcohol for more accurate and deep cleaning.


You will notice that after you have finished cleaning, there will of course be some dust residue at the bottom of the CPU. What do you do now? Replace or change the covering? No! All that you have to do is wipe it off clean or suck up the dust with the vacuum cleaner.
