Thermal Paste Review 2019 — Protect Your Processor

You might be aware of the heating issues of CPU and possibly it will be bothering as you as well. But, you can get rid of it with a thermal paste.

In this article, we will discuss the best thermal pastes for the year 2019. This discussion will help you choose the right one for your PC.

What does Thermal paste do?

Thermal compound reduces the gap between the heat sink and the CPU/GPU. This gap-filling improves the overall cooling. It conducts the heat from the CPU/GPU and transfers it to the heat sink. As a result, the temperature of the CPU/GPU is lowered down. 

Why does your PC need a thermal paste?

Often it is ignored or not considered necessary but it is very important for your PC. Your processor always gets heated up while in use. Although it has heat sink and fan that avoids it get being overheated. Yet, it is not enough and there are high chances that it can damage your processor and graphics cards. So, better safe than sorry.

What about the existing paste on the CPU?

It is highly recommended to remove the old thermal paste first. For that, you can use 99% isopropyl alcohol. Just pour some quantity and wipe it off with a cloth, as simple as that. After that, you can apply the paste.

How to important is to apply the paste in the right way?

But remember that you need to apply the paste in a correct manner. Else, even the best thermal paste won’t perform well and won’t meet your expectations.  Make sure that you don’t apply too much or too less thermal paste on the processor. The simple way is to put a reasonable amount of paste on the center of the surface. It will spread itself as you will put the heat sink on it.
