10 Best CPU Thermal Paste 2022 – Reviews & Guide


CPU thermal paste can be used between the heat sink and CPU to help improve the transfer of heat between the two components. Although less heat will be transferred to the heat sink than if there was direct contact between the two, a good thermal paste will maximize the amount of heat that is transferred.

The thermal paste between your CPU and heatsink is the most important part of your cooling system. Not only do you have to choose a thermal paste that performs well, but you have to apply it properly. So why not choose something that’s easy to apply?

One of the most important things to consider is thermal paste. Whether you’re installing a CPU, GPU, or heatsink into your PC build, you’ll need it. The thermal paste helps reduce the amount of heat that builds up in computer components by filling in microscopic imperfections on the surfaces where each component touches your heatsinks. While this paste isn’t absolutely necessary (though we highly recommend it), it can make a huge difference when it comes to keeping your PC running cool and quiet.

To help you find the best thermal paste for your PC build needs, we’ve put together this list of our top picks for different types of thermal pastes and thermal pastes for different uses.

Is expensive thermal paste worth it?

It is worth it to buy expensive thermal paste because the more expensive thermal paste typically performs better than the cheap stuff. However, this is only true if you are using it on a high-end CPU or GPU. For most people, it is not worth it to spend more than $5 on thermal paste.

There are numerous different types of thermal pastes out there on the market today, including ceramic, metal and non-metallic (also known as non-conductive) thermal pastes. When choosing a thermal paste for your PC, you need to consider what kind of computer you have and what type of usage you will be putting it through. You should also make sure that you purchase the right amount so that you do not end up wasting money by buying too little or too much of it.
