What is thermal paste and why do you need to replace it?

Thermal paste is a substance that is used as a heat conductor between different components. It is a paste that has a very low thermal resistance, which means it has the ability to conduct heat very well. When the thermal paste is used, heat is conducted from a component that is hotter, such as your processor, to the cooler component, usually your heatsink. It is usually not a good idea to buy the cheapest thermal paste you can find, especially if you are overclocking your CPU. This is because the paste will conduct heat better than the stock paste and if you don’t apply it correctly, you will not see any results when you are overclocking. The thermal paste serves one purpose, and one purpose only – to transfer heat. Thermal paste is not made to be permanent, it will dry out or become worn with time and it will need to be replaced.

Why thermal paste gets old?

If you are like me and work in the computer industry, then you probably have heard from customers, friends or family that their computer is not working as well as it used to. The problem is always one of the following: either the computer is too slow, the internet is not working or the fans are making a lot of noise. I use to explain to people that the computer is only 4 years old and that these are normal problems for a computer that is 4 years old.

But now I have found a solution that might help people understand that computers will always have problems and that the problem isn’t that the computer is aging but that the hardware is not working as well as it used to. The solution is to explain to people why their computer is slowing down, why their internet is not working or why the fans are making too much noise and why the solution to the problem is replacing the thermal paste on the CPU.

How to clean off thermal paste

If you are having difficulty removing all thermal paste from your CPU, begin by wiping it with a microfiber cloth.

Wipe the top of the CPU gently with rubbing alcohol while dipping a cotton swab into it; this will help loosen any hardened thermal paste. To help remove the stubborn paste, you may use a plastic spudger.

If you still have any thermal paste left, you can use a clean portion of the cotton cloth or paper towel to remove it. The alcohol will evaporate almost instantly.

To remove any old thermal paste remaining on the underside of the cooler, repeat the steps above.

How to apply thermal paste

Place a small amount of thermal paste in the centre of your CPU after it has been installed on your motherboard.

Apply top-down pressure to the cooling unit as you install the CPU cooler. Installing the cooler will distribute the thermal paste evenly because the cooler’s pressure will do that for you. There is no need to spread paste itself.

Check the edges of the CPU after installing the cooler to see if any thermal paste spilled over, and clean it if necessary with a microfiber cloth or paper towel.
