Storming the internet to find out what is thermal grease? This article is for you. It’s a fact that the term thermal paste is known to people who build a PC. Normal people like us are not very familiar with the term as most of us buy a PC instead of building one.
When you build a PC, other things like a graphics card, new processor, and RAM excites you more than the thermal paste you just bought. You need thermal paste for your PC’s health because without thermal paste your PC won’t survive for long.
Thermal pastes have other names like thermal grease and thermal compound. In this article, we will focus on what thermal grease is and what role it plays in a PC. Let’s get on with it then!
What Is Thermal Grease?
It is a substance that is applied in the middle of the processor and the heat sink, to apply the thermal grease you need a tool. When you buy the small tubes of thermal pastes which are available in electronic stores, they come with a miniature shovel-like tool known as an applicator.
While building a PC you should use thermal grease, as it runs the PC smoothly. There are some PCs that already come with applied thermal grease, but there are hardware fanatics who will take things in their hand, like apply thermal grease manually, that too as well using their favorite brand.
The Role Of Thermal Grease
The main job that the thermal grease plays is to shift heat away from the CPU and into the heat sink. The job of the heat sink is to then bar the heat from the hardware. This keeps the CPU cool especially when there is a lot of pressure on it.
Some manufacturers use “stock thermal paste” on a pre-built computer, but they also use some other compounds instead of other pastes, which are not that effective at conducting heat.
As we know CPUs can get hot due to a lot of pressure, therefore it is essential to move the heat as fast as possible. Since air is a bad conductor of heat, you need to keep as little air as possible in between the CPU and the heat sink for fine transfer.
If you have handled the CPU and taken a tour inside of it, then you will see that the heat sink is very close, almost pressed tightly against the CPU. Maybe it seems like it can stop air from getting in, but the scientific fact is, nothing can be so tight to keep air out of it.
This is when thermal grease is needed, it not only is a great conductor of heat but also makes its way in small gaps and channels, which creates a tight air seal. Therefore it boosts the heat transfer.
With time thermal grease gets dry and therefore it does not work well, so applying it again is a good move.
Why Need Thermal Grease?
Many of us have this misconception that thermal grease is not more important than a processor or power supply. Yes, your computer will boot without thermal grease but keeping it alive for a long time will be impossible for you if you don’t apply thermal grease.
If you think it’s going to be fine for your computer to work without the grease, then you will have random shutdowns, shuttering, and blue screens. Don’t tell me I didn’t warn you.
I know nobody gets excited when they buy thermal grease, but it is the most important part while building a computer.
Many of you might think that the grey goop will just destroy the look of your expensive processor. In that case buy a heat sink that already has pre-installed paste, though it is not of the best quality, at least it will make the installation easier for you.
How Do You Apply Thermal Paste?
If you want to search the internet for the best way to apply thermal grease, there are disturbingly unstable debates. Some have strategies, theorems and some give advice on it.
The simplest yet right method to apply thermal grease in your PC is: place a drop that looks like a pea on the middle of the processor, now, stick the heat sink with the processor. Apply pressure on the four sides equally. This pressure spreads the paste evenly on the surface.
If you get an applicator with the thermal paste tube, it’s well and good, as it will be easier to apply it. People often ask how long does thermal paste last? To which an expert has answered that every two to three years is a good idea for changing the paste.
Best Thermal Grease Brands
It varies among people because everybody has their own favorite brand. But there is a way of how you can choose from so many brands, take a look at the test results and base your decision on raw data.
The computer goes through a test to finally call a thermal paste worth the money. The computer’s idle temperature is measured by a tester first, then a brand of thermal paste is applied to the processor. Then the computer is put through a stress test. The tester monitors the maximum temperature of the processor it hits, during the test.
The next process is to compare the max temperature to the idle temperature. If there is a smaller difference between both the temperatures, then the thermal paste used is considered better at removing heat.
Conclusion
This article has information about what thermal grease is, how it is used, and the brands that can be used. This article is for the hardware fanatics as well for those who want to build a PC but know less about thermal grease. If you are reading the conclusion that means you are done eight the article.
