10 Best Thermal Pastes for CPU You Can Buy Now

Computers overheat and have heat sludge components to mitigate the heat. A heatsink is a passive heat swap that uses electronic equipment to dissipate heat and use a liquid or air coolant to monitor the heat from the system. This is necessary to prevent overheating as effectively as possible at a basic level. The thermal paste is part of this whole cooling equation.

The CPU coolers bundled with the processors that are today on the market are comparable to each other and do not offer the best cooling efficiency. This is exactly why most buyers tend to purchase better aftermarket coolers for major thermal efficiency improvements. Similarly, the thermal paste that typically comes with these coolers is not similar to the best.

Therefore, we strongly suggest the purchase of a high-quality thermal paste if you hope to increase the absolute best thermal efficiency out of your CPU. There are many in the market, which one you want is the 12 best thermal paste for CPU to buy, if you’re confused about.

Best Thermal Pastes for CPU

1. Gelid Solutions GC-Extreme Thermal Compound

2.Great thermal paste for overclocking – Noctua NT-H1

Overclocking your PC creates a great deal of heat, and the Noctua NT-H1 thermal paste is made exactly for this purpose. It keeps a computer’s CPU up to two degrees cooler, and the application process is remarkably easy with no settling time required. It’s also a very cheap alternative, though it should be noted that Noctua’s offering actually includes less of the paste itself (which is how the company keeps the price down).

3.Thermal Grizzly Kryonaut Thermal Grease Paste

The Thermal Grizzly Kryonaut is right at the top with respect to cooling performance, if you plan to push the CPU to its limits by overclocking. Thanks to its 12.5 W/mK thermal conductivity that is quite high with a roasting rack compound, it delivers maximum heat transfer between your CPU and the cooler. It uses a special structure that prevents the drying process up to 80° Celsius at temperatures. The Kryonaut can currently skillfully fence some of the world’s most popular thermal compounds.

4. Cooler Master MasterGel Maker Nano Thermal Paste

This is a comparatively recent but very premium thermal paste produced by Cooler Master for maximum thermal performance that can be expected from a fat-based compound. It has a thermal conductivity of 11 W/mK, which gives the most popular GC Extreme a run for its money. As far as Cooler Master’s bold assertions are concerned, the thermal paste has nano-diamond particles capable of handling a wide range of temperatures ranging from-50 to 150°C. This thermal paste also has excellent viscosity, making it easy to spread and remove without cracking or drying out. All in all, this affordable thermal paste is well suited for people looking forward to overclocking their K Series CPUs.

5. Best carbon-based thermal paste — Arctic MX-4

6. Arctic Silver 5 Thermal Paste

The Arctic Silver 5 was considered a pinnacle of thermal paste, offering the best possible thermal performance over time. Although quite a few relatively newer thermal compounds have recently outperformed, it is still the most popular thermal paste used by enthusiasts and overclockers all over the world. The Arctic Silver 5 is made of 99.9 percent pure micronized silver, as the name suggests. However, it’s not electrically conductive, so there’s no need to worry about it. Its thermal conductivity is measured at 8.7 W/mK by the company, which is slightly better than the GC-Extreme and even the Arctic MX-4.

7. Noctua NT-H2 Thermal Compound

The Noctuna NT-H1 was one of my favorite thermal compounds that I recommended to many of my friends and family who were looking for a thermal paste. Now, the company has launched a much-improved version of the NT-H1. Dubbed as the Noctua NT-H2, it is a premium-grade thermal compound that ensures optimal heat-transfer from the CPU or GPU to the heatsink for bringing the best cooling solution. The NT-H2 uses a new fine-tuned mixture of metal oxide micro-particles for even lower thermal resistance and reduced bond-line thickness at typical mounting pressures. It is also not conducive to electricity thus ensuring that there’s no chance of a short-circuit accident.

8. Thermal Grizzly Conductonaut Thermal Grease Paste

With an outstanding thermal conductivity rating of 73 W/mK, Thermal Grizzly Conductonaut is one of the best thermal pastes you can buy in 2019. It will reduce the operating temperature of the CPU or GPU by 10°C, giving you a significant headroom for overclocking. It has a peak operating temperature range of-50°C to 180°C, which is one of the best on the market. Thanks to its exceptional results, it has become a hot paste for computer nerds who want to run their machines to the extreme. If you want to test the limits of your system as well, you can buy.

9. Antec Formula X Thermal Paste

According to the makers, this paste can make sure you get good performance even in extreme environments, when temperatures are ranging from -30~240℃. Apart from that, the Formula X paste is easy to apply, even if you are a beginner and it comes with all the tools you need like a scraper, grease, rag, fingertips etc. 

It is also highly durable, not volatile, odorless, and non-corrosive and very importantly, comes at a great price tag. The Antec X thermal paste is a high-performance heatsink paste compatible with all CPU coolers and has a high thermal conductivity of 11 w/mk, which is pretty good as far as thermal paste is concerned, which means it can quickly dissipate heat from the CPU.

10.  Thermalright TF8 Thermal Compound Paste

Like other successful thermal pastes, the Thermalright TF8 does not contain any metal, thus eliminating the risk of short-circuiting accidents. It’s got a very long life, too. When applied, it will work effectively for up to 8 years. That means you don’t need to open your device every couple of years to re-apply it. Talking of some numbers, the TF8 has a thermal conductivity rating of 13.8 W/mK, which is one of the highest thermal conductivity ratings we have seen in thermal paste. What that means is that it will transfer heat from your CPU to a heat sink to give you better cooling. Overall, one of the best thermal paste on the market.
