How to Cleaning Thermal Paste?

In this article I’ll teach you how to correctly Cleaning Thermal Paste from the CPU. Thermal paste is required while creating a computer to guarantee that the central processor unit (CPU) does not overheat. The paste is a conductive material put into your CPU to provide as much contact as possible between the hot CPU and the cooler.

Your CPU is referring to overheating without thermal paste. Whether you’re putting thermal paste on a new build or an older computer that has to be cleaned off the prior paste.

It can result in various performance issues and possibly affect the lifetime of your computer. PC maintenance includes a variety of tasks that many people ignore, such as how to clean the thermal paste from your CPU. Existing computers may also need fresh thermal paste since it tends to dry over time.

Moreover a paper towel is the most straightforward technique to remove the old thermal paste. To start, you must take basic steps to protect yourself and your computer. Then it’s only a matter of cleaning and replacing the old paste.

What is Thermal Paste?

A material known as the thermal paste is sensitive to temperature and aids in transferring heat by filling up any air gaps that could typically exist between two surfaces. To guarantee that heat is dissipated from the processor as efficiently as possible, technicians insert a small amount of thermal paste between the CPU and the CPU cooler while assembling computers. Your CPU would overheat without using thermal paste, resulting in damage.

How to Cleaning Thermal Paste

You must first clear off the old thermal paste from a functional computer before applying the new thermal paste. Ensure the CPU cooler has been removed before you start and that you can see the thermal paste, often white or gray. I’ll explain how to clean the thermal paste from your CPU here:

You will need the following items:

  • A microfiber cleaning cloth (not paper towels, as they can scratch the surface)
  • At least 90% rubbing alcohol
  • Cotton swabs (optional) 
  • A plastic spudger

I’ll explain how to clean the thermal paste from your CPU here:

  1. Gently wipe the old thermal paste away using a dry microfiber towel. It will aid in the removal of any “loose” bits.
  2. To the microfiber cloth, dab a small quantity of your preferred solution (isopropyl alcohol or thermal paste cleaning).
  3. Wipe the CPU from top to bottom until no visible thermal paste remains. Do it cautiously and slowly; otherwise, the CPU may be damaged.
  4. Take care to clean around the borders as well.
  5. Allow the CPU to dry. The drying period may vary depending on the solution used; however, experts recommend waiting around an hour. If you used a thermal paste remover, the directions should specify how long you should wait.

How often should Thermal Paste be cleaned off the CPU and Reapplied?

Thermal paste should be reapplied every 3 to 5 years, depending on the operations you do on your computer and the quality of the original thermal paste. You may need to reapply it for a variety of reasons, including:

  • If the original thermal paste was not correctly applied.
  • Your CPU is operating at temperatures that are greater than typical.
  • You’re either removing (for cleaning) or changing the CPU cooler.

Why Is It Necessary To Reapply Thermal Paste?

Thermal paste is the substance applied between your CPU’s lid and the baseplate of your CPU cooler.  Nevertheless, thermal paste does not stay forever. Because thermal paste may dry up and become less efficient at transporting heat from the CPU to the cooler over time, you should wipe it off your CPU and reapply it regularly.

While the thermal paste is unlikely to dry up soon, there are multiple causes you may need to reapply it.

Cleaning your CPU cooler is typically simpler after dismounting it, and you will need to reapply thermal paste before remounting it. If you purchase a new CPU but still using the old cooler, you’ll need to remove it for the new installation and then reapply thermal paste before reinstalling it.

Tips When Purchasing Thermal Paste

Several thermal pastes are available on the market, making it difficult to decide which one to use. Here are a few things to consider:


A thermal compound with a high viscosity will be easier to apply and attach to the surface.


If you’re using the thermal paste for the CPU, you only need a minimal quantity. Furthermore, you won’t be able to reuse it since opened thermal paste will expire before you need to reapply it again.


Thermal paste is classified into two types: conductive and non-conductive. PC Gamer offers a helpful rundown on the advantages and disadvantages of each kind. As a general guideline, if you’re unskilled, stick to non-conductive types.

Metallic thermal pastes might short out your system if they get on the motherboard. However, their heat conductivity is more significant, as is their pricing, and they are therefore aimed toward extreme or record-breaking builders.


This article will explain Cleaning Thermal Paste from the central processing unit (CPU). If you wish to remove thermal material from your CPU, I hope this article will be helpful to you. In addition to alcohol and water, you may use various other items to clean them. Moreover a paper towel is the most straightforward technique to remove the old thermal paste. However, thermal paste does not have an indefinite life span.

The thermal paste can dry up over time and become less efficient at transporting heat from the central processing unit (CPU) to the cooler; thus, you should periodically clean the thermal paste from your CPU and reapply it.
