Best Thermal Pastes for CPU You Can Buy (2021)

Best Thermal Pastes for CPU

Are you a big fan of overclocking? If you have been one so, you probably know that CPU temps seem to rise when you overclock it. So basically, to protect your processor we have to use a thermal paste. It can fill in all nooks and crannies and bind both surfaces of your processor along with its heat sink thus ensuring that the heat generated is adequately taken care of by the heat sink attached to your processor. We have compiled a list of some of the thermal pastes that are out there in the market.

Best Thermal Pastes for CPU

1. ARCTIC MX-4 – 4grams

Arctic MX-4 comes with an ideal consistency, and it is relatively easy to use, even for beginners. This thermal paste compound is composed of carbon micro-particles which lead to a too high thermal conductivity, and hence it guarantees that heat produced from the CPU or GPU is dispersed rapidly and efficiently. Moreover, it is safe to use as it does not contain any metallic particles so electrical conductivity would not be an issue. It is a value for money product.

2. Cooler Master High-performance thermal paste

It is perfect for CPU, chipsets on Mainboard, VGA card, etch, and it is easy to use. It comes with a ZIF Socket Templates that ensures correct applying area with various CPU socket types. It is a thermal compound, and it is designed to act as a chemical layer between the sources of heat. These products are intended for high-performance CPUs and GPUs. So don’t fret when overclocking your beast.

3. Thermal Grizzly Kryonaut

The Thermal Grizzly Kryonaut is made for the most dedicated and hardcore PC gamers. This paste comes with no conductive power, and this makes it an ideal thermal pastes. Moreover, it comes with no settling time requirement. Hence, you can easily apply it to your computer. However, it has three to four per cent lower temperature cooling capabilities than Arctic Silver 5.

4. Arctic Silver 5 Thermal Compound

Arctic Silver 5 is a thermal paste that is made almost entirely of micronized silver. However, it is still a ceramic paste, but it should not be placed on other components in your computer. The micronized silver helps in conducting heat, meaning it will help dissipate more heat when the CPU is working overtime. Unlike other thermal pastes, this thermal paste does have a settling time attached to it. As it is made up using silver, it is undoubtedly the best paste to purchase.

5. CORSAIR TM30 Performance Thermal Paste

It is a premium zinc oxide-based thermal compound for optimal thermal performance to improve heat transfer and lower temperatures. It comes with enhanced CPU cooling that features ultra-low thermal impedance that lowers CPU temperatures vs ordinary thermal paste. Its low viscosity allows it to quickly fill microscopic abrasions. It then channels in your CPU’s heat spreader and cooler’s contact plate, for maximum thermal transfer area. Overall, it a reliable and safe thermal paste.

6. Nabob Deals Arctic Silver 5 Thermal Cooling Compound

Arctic Silver 5 does not contain any silicone, and the suspension fluid is a proprietary mixture of refined polysynthetic oils. It comes in the form of the syringe, and hence the consistency is engineered for easy application. It contains over 88% thermally conductive filler by weight. Arctic Silver 5 offers excellent performance and stability because of its unique high-density filling of micronized silver and updated thermally conductive ceramic particles.

7. Thermal Grizzly Hydronaut High-Performance Thermal Paste

This high-end thermal paste is recommended for people who want to try grease reasonably. It works by reducing the volume of grease and replacing the container with a simple one. It is priced reasonably, and it is easy to use as it provides excellent heat transfer performance for overclocking. Since it does not contain silicone, it is flexible and can be applied easily. You will also receive a spatula with a thermal Grizzly logo for the convenient application.

8. ARCTIC MX-4 – 8 grams

Arctic MX 4 is a very popular thermal paste because it is inexpert I’ve and very easy to use. You don’t have to wait for it to settle and the applicator doesn’t have any metal components, so it won’t conduct electricity. MX-4 is ideal for CPU and GPU cooling as it sports an excellent temperature reduction performance.


There are more of these thermal pastes out there in the store (offline or online), but when it comes down to your own use, you can go ahead and choose anyone that seems to fit your purpose. These products allow you to keep your processors cool and help increase their longevity. In case you are wondering on when you should be replacing the thermal paste, a general suggestion would be to change it every 1-2 years.
