    The Best Thermal Paste for CPU Cooling in 2020

    -

    Most people think of CPUs, RAM sticks, or drives when considering how to improve an old or new computer’s performance. But just like the oil in a car, there is an element that allows a computer to run smoothly and is usually overlooked: thermal paste.

    A computer’s CPU or GPU tends to heat up when working hard, which can result in thermal throttling if its temperature is not managed properly. A computer can have multiple fans or liquid refrigeration, but these elements are only as good as the thermal paste allows.

    Thermal paste is the medium that allows the heat produced by hardware to be transferred to the cooler solution, which will then get rid of it to keep your computer fast and fresh. Not all thermal pastes are the same, and you need to get the right one for your rig.

    Choosing the right thermal paste for your computer is essential to take advantage of everything it has to offer you, be it watching a show on your favorite streaming platform, playing videogames professionally, or creating the next big machine learning platform.

    Thermal Paste Application 101

    How to apply thermal paste
    Image: Corsair

    While applying thermal paste to your computer is an easy process, there are some things you will need to keep in mind to ensure you get the best out of it.

    If you are building a computer, make sure to insert your CPU in the Motherboard’s socket. If your computer is already built and you are just trying to replace the paste, remove the cooler that is located over the CPU.

    Once you have done this, you will need to make sure the surface is clean before applying the thermal paste to ensure maximum efficiency. You can do this by cleaning the surface with a microfiber cloth or paper towel and Isopropyl alcohol.

    Now that the surface is clean, you can apply the thermal paste. There are different methods to do this, each with a large following claiming it to be the best. However, the dot method is the easiest and will give you good results.

    Just use the applicator and add a drop of thermal paste the size of a grain of rice on the center of the CPU. It is a common mistake to think that more thermal paste will give you more heat dissipation, but the opposite is the case.

    Place the cooler over the CPU as straight as possible, as moving it to match the holes once in contact with the thermal paste will cause it to be spread unevenly. If you fail to do this, just clean the surface and try again.

    If you have your own method and you feel comfortable with it, use it. Just keep in mind not to use too much or too little thermal paste, to ensure the proper distribution, and to avoid spilling it over the motherboard.


    Types of Thermal Pastes

    The first thing you should consider when buying thermal paste is the purpose of your system. Are you a casual user just looking to work on some documents and browse the wave? Or a power user looking to squeeze every bit of processing power your hardware can provide?

    Knowing this is fundamental for choosing your thermal paste based on elements like composition, consistency, duration, thermal conductivity, and of course, price.

    You don’t want to buy a zinc oxide-based thermal paste for your gaming Intel Core i7 10700K processor or a liquid metal thermal paste for that computer that is only useful for basic tasks. Any of these choices would be either under or overkill and affect both your pockets and rig.

    So let’s have a short discussion about the different aspects you should consider when buying a thermal paste.

    There are a lot of different ingredients that can be used to create a thermal paste, each of them offering different performances that result in different prices. While there are many different types of compounds, we can divide them into 4 main categories: Silicone, ceramic, metal, and carbon-based thermal pastes.

    Silicon Thermal Pastes

    Chances are your computer came with this type of thermal paste pre-installed. This paste is easy to use and safe but provides the lowest grade of heat conductivity of any type of thermal paste.

    The low duration of this paste also means that it is recommended to change it more regularly and at the time of getting your new computer, as most times it will have lost a lot of its effectiveness by then.

    The Zinc Oxide silicon thermal paste is one of the most common pastes out there, offering the lowest price as well as capabilities. However, this does not mean that this paste is not useful for users but quite the opposite, it will work for most people looking to surf the web and create documents.

    Ceramic Thermal Pastes

    Being one of the most common types of thermal paste, they are considerably cheaper and safer than the next types due to not being electrically conductive.

    This makes them an excellent option for inexperienced users who don’t want to risk doing any damage to their computers or who just don’t need the extra conductivity.

    This type of paste is recommended for computers designed for regular use and as so, it should never be used if you are planning on doing video editing, visual design, intense programming or gaming, or anything that might require you to overclock your CPU.

    Metal Thermal Pastes

    These pastes contain metals like copper, aluminum, silver, or gold which provide great thermal conduction properties but also make them electrically conductive.

    This electrical conduction property means that users need to be careful when applying it, as any unintended drop or application on the wrong part of the motherboard could cause issues.

    This type of thermal paste is usually chosen by gamers due to the high performance it provides while also having a good price when compared with other options.

    Carbon Thermal Pastes

    We are now entering the area for power users or those willing to spend extra money to ensure their hardware operates as well as possible.

    Carbon-based pastes offer great heat conductivity while also having low electrical conductivity, which makes them a superior alternative to metal thermal pastes for most users.

    There are different types of carbon thermal pastes, such as those that contain diamond powder, graphite, and carbon nanoparticles.

    Conclusion

    Choosing the right thermal paste for you doesn’t need to be hard, but it is fundamental to your computer’s health and performance. Make sure to take time and understand everything that goes into the decision making process, and get the right thermal paste for the job.

    By making sure to choose the best option for you when taking into consideration price, performance, ease of application, and safety, you will ensure you will be able to use it smoothly and without headaches.

    All of the options we have provided you are great for most users, with the best options being for more demanding users, so as long as you identify your needs there is no way for you to go wrong.
