If you’re a PC gamer, you might already be somewhat acquainted with these terms, but you might not know precisely what they indicate.
This guide will explain what these things are, how they are utilized, and compare thermal paste vs. grease vs. pads to explore how they differ from one another.
All of these things are thermal (heat) conductors. This means they will absorb the heat produced by the CPU or the GPU (the chip specifically) and conduct it securely and efficiently to the heatsink, from which it will be further dispersed.
It’s crucial to know why there is even a need for such things, so let’s take a closer look.

Why Heat Needs To Be Dissipated
The processing unit (whether it is graphical or central) has to perform an incredible amount of calculations each second. They accomplish this by transferring electricity, which in turn generates heat. Due to the sheer number of processes that the chip performs, it can become extremely hot.
This is where the heatsink and fans come in as the most prevalent cooling methods. There are also alternative methods, such as water cooling, but the heatsink/fan combo is the most prevalent one because it is straightforward (and comparatively cheap).
Before that combination enters the picture, there needs to be something that will conduct the enormous amounts of heat from the chip to the heatsink. That is where a thermal paste or thermal pad comes into play.
Thermal Paste
Before proceeding, we should rapidly get this out of the way. Thermal paste is the same thing as thermal grease.
The phrase thermal paste is commonly used, thus we will employ it to explain its purpose. Other terms for thermal paste include thermal compound, thermal goop, thermal gunk, heat paste, and others.
Thermal compound is distinct from a thermal adhesive, which you shouldn’t use unless you know exactly what you’re doing. Adhesive only needs to be used in extremely rare cases, as the chip is already pressed down and secured using other methods.
As its name suggests, thermal paste is a liquid that will transfer heat and is situated directly between the chip and the heatsink. Because of this, it’s vital to know how to apply the paste properly. If you’re able to do that, then it will fill all of the gaps and make sure that the heat is transferred efficiently.
The most commonly used ‘intersect‘ and ‘spot‘ methods will be adequate to ensure the equal distribution of thermal paste and, thus, the uniform dispersal of heat.
Thermal Paste (Thermal Grease) vs. Thermal Pads
Thermal pads are not the same thing as thermal paste. They are solid and provide a particular sort of coverage in the way that it might leave some air pockets, which is something that you do not want.
It would be unfair to say that thermal pads don’t provide proper heat conduction when, in fact, they do. Most of the time, the distinction between a thermal paste and a thermal pad will be almost impossible to discern in terms of performance.
Thermal pads are significantly easier to install, and you can’t really mess anything up as you might with a thermal paste. With the paste, someone new to the process or uncertain about it might accidentally apply too much paste, which can lead to a specific set of problems.
However, properly applied thermal paste can be a noticeably better heat conductor than a thermal pad.
Ultimately, our advice is to go with a thermal pad if you’re uncertain how much thermal paste you should apply or consider the procedure too intricate. However, if you’re willing to perform the process, then a thermal paste is an excellent option.
