Best Thermal Pastes 2022: Buying Guide

When a plethora of best options is present before us, we tend to get confused which one to opt for. Therefore, you should consider several factors before buying the best CPU thermal paste in 2021.

Does your computer overclock?

The first and foremost thing to consider is the workload of your computer. Does it overclock? Or you do very nominal work on it. If you have a demanding workload, then you need to use the best thermal paste to make sure that your system does not heat up when used extensively. Or else there are chances for the system to crash when the processor is producing too much heat.

Applying method

Just buying the best and most expensive paste is not going to solve your problem at all. You have to make sure that you have applied it in the correct manner and amount so that heat can get transmitted to the cooler.

Type of paste

There are basically two kinds of thermal compounds

  • conductive
  • non-conductive

The conductive pastes are composed of metals. The nonconductive ones are made up of non-metals like silicone and zinc. While, the conductive ones are better performers, but users need to extra cautious while applying it because if the slightest amount of it spills into the motherboard it can cause short circuit thereby damaging the motherboard.

On the other hand, with non-conductive paste users need not worry about such things. So, the non-conductive ones are recommended for the beginners.

How to apply thermal pastes to CPU?

thermal paste is a crucial component in keeping your computer cool. It is a substance that is applied to the surface of a CPU or GPU in order to create better contact and thermal conductivity between the two. This helps to transfer heat away from the components and into the surrounding air more effectively.

Applying thermal paste may seem like a daunting task, but it is actually quite simple. First, remove any existing thermal paste from the surface of the CPU or GPU. Next, apply a small amount of thermal paste to the center of the component. Be sure to use an even layer that is not too thick or too thin.

Finally, use a spreading tool to spread the thermal paste over the entire surface of the component. Allow the thermal paste to set for at least 30 minutes before turning on the computer. By following these simple steps, you can ensure that your computer stays cool and runs smoothly.

Vertical Line Method

As suggested in the name itself, all you need to do is take a small pinch of the taste and apply it on the CPU in a single vertical line. This way the whole of the CPU can be filled.

Pea Method

Apply a pea-sized paste on the IHS and thereafter mount the heatsink on top of it. This is the most popular method amongst all.

Circular Method

In this method, you need to place the thermal liquid in a circular motion on the IHS. But be careful. A uniform thin layer of the compound should be placed on the IHS.

Alternatives to Thermal Pastes

Thermal pastes are essential for keeping your computer cool. They help to fill in the gaps between your CPU and heatsink, and they also help to conduct heat away from your CPU. However, thermal pastes can be expensive, and they can also be difficult to apply. As a result, many people are looking for thermal paste alternatives.

Some common thermal paste alternatives include thermal pads, thermal grease, and thermal adhesive tapes. Each of these options has its own advantages and disadvantages, so it’s important to choose the right one for your needs.

Thermal pads are often the easiest to apply, but they don’t always provide the best thermal conductivity. Thermal grease is more effective at conducting heat, but thermal grease can be messy to apply. Thermal adhesive tapes are somewhere in between, offering good thermal conductivity while being relatively easy to apply.

However, they are not as effective as thermal paste in terms of thermal conductivity, so they may not be the best option for high-performance applications. Another option is to use liquid metal. This is an excellent thermal conductor, but it can be difficult to apply and can cause damage to sensitive components if not used correctly.

Finally, you can try using alternative materials such as carbon nanotubes or diamond powder. These materials have extremely high thermal conductivity, but they are also very expensive and may not be suitable for all applications.

Some Benefits of Thermal Pastes

Applying thermal paste to a CPU can help to improve its thermal conductivity, which in turn can help to improve its cooling performance. Thermal paste is often made from metal oxides or other materials that are good at conducting heat.

When applied correctly, thermal paste can help to fill in any voids or irregularities between the surface of the CPU and the heat sink, resulting in better contact and improved thermal conductivity. In addition, thermal paste can help to fill in any gaps that may be present between the heat sink and the CPU.

By improving the thermal conductivity of the contact between the CPU and the heat sink, thermal paste can help to improve the overall cooling performance of a CPU. As a result, it is an important component for any PC that is overclocked or used for gaming.

Thermal paste is a thermal interface material, often used to fill the gaps and inconsistencies of thermal contact between heat sinks and CPUs or GPUs. Many builders consider thermal paste to be an essential part of any PC build, as it can help improve thermal transfer and prevent overheating.

While there are many different types of thermal paste available on the market, they all serve the same basic purpose: to improve thermal conductivity between two surfaces. In most cases, thermal paste is applied to the surface of a CPU or GPU before a heat sink is mounted.

This helps to ensure that there is good contact between the heat sink and the device, allowing for better heat transfer. In some cases, thermal paste can also be used to fill in gaps or irregularities in the surface of a heat sink. Thermal paste can be purchased from most computer stores or online retailers.

It is important to choose the right type of thermal paste for your needs, as different materials have different thermal conductivity properties. Applying too much thermal paste can also result in poor thermal contact, so it is important to follow the manufacturer’s instructions carefully.

When used correctly, thermal paste can help improve the cooling performance of your PC and prevent overheating.


A plethora of options are available for a different kind of use and all of them are equally capable. So, jot down your priorities and then select the best thermal paste 2021 suit your purpose to run your computer for a long time without compromising on its performance level.
