Dust is one of the components that affect all kinds of electronic devices, including a CPU. To avoid a short lifespan, efficient cleaning can be applied in a few steps. Users who wish to obtain an accurate and error-free result should follow the procedure below.
How to Clean CPU Dust at Home? – An Ultimate Guide
Of course, a CPU has several enemies, and heat is one of the most dangerous. The cooling capacity of a CPU becomes less and less as dust accumulates inside. As the cooling capacity is lower, the heat increases and drastically affects the lifespan of the CPU components.
An efficient and thorough cleaning should be applied every six months minimum or 12 months maximum. Once the user begins this procedure, the computer should be turned off, and the power supply should be disconnected.
The surge protector should also be disconnected to avoid beginner’s error. Once all these conditions are met, the computer case must be opened. Some computers require simple tools, while others require special screwdrivers.
The computer case must be opened to apply an efficient cleaning one way or another. In no case is it possible to use a complete cleaning through the air ducts without removing the computer case.
1. Use Compressed Air
Among the tools that can be used to apply this cleaning, compressed air is one of the most recommended options. However, it is necessary to learn how to use compressed air inside the computer. Some parts or components may be somewhat vulnerable to excessive air pressure.
While using compressed air, you should keep a safe distance from each of the most critical components. This means staying away from expansion cards, processors, memory, motherboard surface. After making a general pass with the compressed air, you can proceed to the next step.
2. Remove all Dust Accumulation
A can of compressed air is more than enough to work with the CPU fans. This is where a large amount of dust usually accumulates, which turns out to be very problematic later on. When the compressed air is applied, the user will notice that the fan will start spinning.
It would be best to use your finger to hold the fan completely still while using the compressed air. At the same time, it should be considered that the CPU fan blades can be somewhat fragile. So they should not spin too fast as they may crack or break.
When it comes to applying the finishing touches to the fan, a cotton swab can be used. The fan blades can be cleaned with this implement and some isopropyl alcohol. These items are highly effective in providing a much longer-lasting result.
On some occasions, the design of the fans or the CPU may make the task more difficult. In such a case, it is recommended that the user remove the fans to clean them more conveniently and efficiently.
3. Working with the Power Supply
Another of the most problematic dust accumulations is explicitly generated on the power supply. The same can of compressed air can also be used for proper cleaning. As much dust accumulation as possible should be removed without damaging the more fragile components with the air pressure.
In some cases, users can be provided with a dust filter located underneath the power supply. For a much more complete result, it is recommended to clean this dust filter. Of course, the lifespan of this component must be taken into consideration, as some parts are only of limited use.
When the user decides to clean the dust filter and the power supply, a longer-lasting result can be obtained. Even when the power supply becomes too hot, an explosion may occur. This can undoubtedly lead to more significant damage to other dust accumulations from other components.
4. Clean the Rest of the Components
Using the same can of compressed air, short bursts should be made to clean the rest of the fan and heat sink. These components are usually mounted on the processor and collect dust like the rest of the ingredients. It is recommended to remove the processor fan and heat sink on some occasions.
In particular, too thick a layer of dust can accumulate. When this happens, remove these components while using the same can of compressed air. So also, the user needs to remember to clean the thermal grease off the heatsink and processor.
When the heat sink must be replaced on the processor, new thermal grease must be added. This is one of the most straightforward steps, but it complements the cleaning procedure mentioned above.
6. Correct Way to Remove Thermal Grease
The user can use 99% isopropyl alcohol together with a lint-free cloth. In this way, the thermal grease mentioned above can be cleaned. To avoid leaving residues, it is not recommended to use less concentrated alcohol. Other solutions are also available to remove this thermal material.
The user needs to finish the procedure using the can of compressed air over each of the computer ports. A cotton swab with isopropyl alcohol can be used again for each of the external vents.
A cleaning as mentioned above needs to be applied every six months. This is specifically recommended when the computer is on the carpet or the floor. When the computer is on a desk, cleaning can be applied every 12 months.
Remembering the correct date to reapply the cleaning process can be very beneficial for a CPU. The cleaning above procedure will allow the user to get the most out of the lifespan of their PC. At the same time, a few implements are needed to complete this procedure.
Undoubtedly, this can allow a user to avoid spending money every year on the purchase of dust-damaged components. This is why many users decide to learn how to perform this procedure and take care of their PCs.
