If you have been into PC building, you must have heard of thermal paste. But what is it, and why are all enthusiastic PC users so obsessed with it? Is it that important? So to help you with these vague queries, we will cover a comprehensive discussion about the best thermal paste in this article. You might not consider it an essential component of your rig, but it guarantees the health and sustainability of your system. A thermal paste is a chemical compound that helps efficient thermal conductivity due to its nature and composition.
This polymerizable liquid matrix consists of substances that are electricity insulators yet conduct heat. This simple thing changes the thermal game and makes a huge difference. How? Let’s find out! Some manufactures provide components pre-applied with this paste, but most of the time, you have to buy something off the shelves for the sake of your computer. The CPU and the heating are arranged in a tight-squeezed way to avoid the air staying between the two, but no matter how tightly you press the two against each other, the air still stays. So the ultimate solution is a thermal paste that fills the hollow grooves between the processor and heatsink and conducts the heat to provide maximum performance.
This way, it conveniently transfers the heat from the CPU to the heatsink, so the heat does not mess with the internal components. Once it dries out, you can reapply it to reap the same benefits over and over again. Now go ahead and check out the list of most effective thermal pastes that we narrowed down for you.
Quick Shopping Tips:
You can also consider some simple shopping tips to take help for picking the most suitable product.
Thermal Conductivity: The very first thing that you should consider while opting for a suitable thermal paste is the thermal conductivity levels it provides. The thermal conductivity is a parameter to show how efficient the paste is at keeping the system cool. It is the rate of heat transfer from your CPU to the heatsink of your rig. The higher the conductivity rates, the better is the performance. Liquid pastes tend to be more efficient than non-metallic compounds since they have higher conductivity rates than the latter.
Electric Conductivity: If you are new to this area of PC building, avoid getting liquid metal pastes as they are electrically conductive. Slight negligence can cause a short circuit and can burn down the internal parts. So to prevent malfunction and damage of the system, prefer pastes that are not electrically conductive. But it’s a fact that such pastes are more effective for power-consuming rigs. So careful application of such products can guarantee efficient heat conductivity.
Viscosity: Thermal pastes vary significantly in terms of their consistency. Some products are liquid and flowy while others, on the contrary, are thick. Compounds with high viscosity are notorious for tedious application, but they provide safety to the components. Mildly viscous or semi-liquid thermal pastes spread readily and evenly, making the system vulnerable to damage. If applied more than the required quantity, they can run over the surface and seep through the gaps, which is not a desirable thing, right? So use it the right way with expertise and care.
Thermal Design Power: People also call it TDP, and the specification list of your processor shows it. If you know the TDP of your processor, you can guess how the system will get to quite an accurate extent. If your processor is a power-hungry thing and has a significantly high TDP, it will require more effort to cool down for sure. This factor bears importance since it helps you determine the correct thermal paste type for your system. Once you get the paste that matches your needs, your rig’s performance boosts.
Type: There is a wide range of thermal pastes, and there is no standard paste that fits everyone’s needs equally. So you need to choose the right kind of thermal paste for your system according to our rig’s usage and power demands. The most popular types are metal compounds, ceramic compounds, and silicone compounds. All these have different compositions and performance levels. You should avoid choosing sticky and adhesive thermal paste as removing it and reapplying another paste would be challenging that way.
