Are you looking for the best thermal paste? If you’re setting up or correcting any part of your cooling system, getting the right paste is critical for optimum performance. After all, you need to make sure that your CPU stays nice and cool. And that’s where thermal paste comes in.

The best thermal paste transfers the excess heat from your CPU to the heatsink and gives you with a high-functioning rig. If you’re hoping to get the best bang for your buck, we’ve put together a list of the best thermal pastes of 2020. Let’s get started.

What is Thermal Paste?

Thermal paste is a heat-conductive paste placed between a heat sink and the device it is meant to cool. It can also be placed between other components, especially between a CPU and an ac cooler. The thermal paste helps get better heat conduction. Heatsinks, CPUs, and coolers have tiny, invisible imperfections that can potentially trap air and bring down the heat sink’s general performance.

Thermal paste smoothes out these surfaces and makes them work as efficiently as possible. Air isn’t suitable for conducting heat, and conducting heat is what the heat sink is made for. Heat conduction takes heat and transfers it away from the component that is generating the heat in question.

Corsair Tm30 Performance Thermal Paste (Silver)

Corsair TM30 is a premium zinc oxide-based thermal composite. That means it is non-conductive, non-toxic, and safe to use. This 3gm paste can be worked effectively to improve heat transfer. It also helps to lower the temperature of the microprocessor.

It can be used to your CPU and GPU to fill the microscopic abrasions and channels for peak thermal transfer. Corsair TM30’s high-stability liquid paste lasts for years with no drying, cracking, or change inconsistency after the application.

Arctic Silver 5 Thermal Compound 3.5G

It is a conductive thermal paste that includes thermally enhanced ceramic particles. It comes with three unique shapes and sizes of pure silver particles. This particular also ensures the best physical contact between the heatsink and CPU core along with electrical conductivity.

Keeping the conductive nature in mind, you must apply it very carefully. If used to the microprocessor’s pins or other such electrical pathways on the circuit board, it can cause electrical shorts.

Noctua NT-H1 Thermal Compound

Noctua NT-H1 is a perfect thermal compound that can be used effectively for optimal thermal performance. Usually, it won’t depart, run, migrate, or bleed, and it provides long-term stability.

Noctua NT-H1 is a hybrid compound of other micro-particles. It also allows for minimum thermal resistance. Its application is straightforward. This 1.4ml paste can be utilized for at least 15 applications.

Thermal Grizzly Kryonaut 1.0 Gram Thermal Grease Paste 

If your device is having heating issues, then this is the perfect solution to it. Thermal Grizzly Kryonaut is a beneficial thermal paste.

If you are a strong gamer, then you must apply it to your device. It can reduce the temperature significantly. It can be helpful in the cancellation of noise also. It is a 1.0-gram paste but can be applied for many times.

Cooler Master Gel Thermal Paste

A more relaxed Master Gel is an excellent thermal paste that can drop the temperature of your device very effectively. This product comes with a free scraper and an alcohol-based cleaner that will help you clean the CPU and cooler base without damaging parts.

It offers high electrical conductivity. So, it should be applied very carefully. This 1.5ml thermal paste can be used very quickly, and it is not that hard to remove.

How Much Thermal Paste to Use

When gaming on a system, the CPU is the component that will require thermal paste. That said, there are many different ways to apply it. Your goal when applying thermal paste is to make a paper-thin layer of it over your CPU. For this, use just a dot of the paste on every side of your CPU.

How to Apply the Thermal Paste and Remove it

When it comes to applying thermal paste, the first step is to insert the CPU into your computer’s motherboard’s proper socket.

The second step is to place a dot of thermal paste onto the center of the CPU. It should be the size of a small ball bearing, or potentially a bit smaller than a pea. Take the component and press it down on the dot. Lock that component into its proper place. This will spread the drop of thermal paste out. You can always lift the part to see if the paste was distributed evenly. If it didn’t go as planned, mop it up and try again.

If you want to know how to remove the thermal paste, well, that’s pretty simple. Wipe it up with a lintless microfiber cloth (a coffee filter will also do just fine as a cheap option). This will avoid creating even further microscopic holes that reduce head conduction while wiping up thermal grease. If you want to know how to clean the thermal paste, well, that’s the best way. It’s effortless; wipe it up with the proper cloth.


Q: What is the best thermal paste for overclocking?
A: Thermal Grizzly Kryonaut is the best thermal paste for overclocking applications that costs double that of the other carbon-based pastes and is suitable for hardcore PC build users. It is entirely non-capacitive and electrically neutral; no settling time is required; hence it is easy to apply.
Q: Can too much thermal paste be sour?
A: Putting too much paste on a socket generally won’t hurt thermal performance because of the act of tightening down the cooler squeezes out the excess. Too little paste is terrible, but anything above the minimum threshold will have the same effect once the cooler is tightened down.


If you’re seeking to pick up some thermal paste, chances are you already know a bit about building a computer. If you don’t, be sure to read up on the types of components you’re using so you can buy the very best kind of thermal paste for the job.
