If you’ve come across this article, we’re guessing you already know what thermal paste can do. But if you’re not in the know, we’ll break it down. Thermal paste (also known as thermal compound or thermal grease) is used in CPUs and GPUs. A quality thermal paste is meant to improve heat transfer between the processor or graphics chip and the heat sink. Since processors typically generate significant heat during operation, thermal paste fills microscopic gaps between the surfaces. Without it, poor heat conduction can lead to overheating, reduced performance, or even hardware damage.
So, say you’re working on your computer, and you realize you need thermal grease. You’ll need the right kind. While you can go straight to Amazon to buy some, you want to make sure you’re picking the best thermal paste on the market.
Here are some solid options:
Polartherm X-8 Thermal Paste for CPUs & GPUs
X-8 Thermal Paste from Polartherm boasts high thermal conductivity and durability. That means it offers stable performance for budget and midrange systems. This thermal paste, which is ideal for hobbyists and beginner PC builders, comes with a spatula to simplify application. You can also use the applicator or apply it directly. Its nonconductive formula also ensures safe usage on sensitive components, so you’ll have less to worry about.
Reviewers said they liked this thermal paste’s consistency. Several of them pointed out that its nozzle applicator works great for large, vertical items. Customers also appreciated its preloaded syringe.
Polartherm X-10 Thermal Paste for CPUs & GPUs
X-10 Thermal Paste is an upgraded version of the X-8. This solution offers increased thermal conductivity in comparison with X-8. That means it’s more effective for midrange and high-end systems that require enhanced cooling. Its formulation aims to help with long-term performance and offers good resistance even in the case of pump-out effect.
Its included spatula makes application seamless, much like with the X-8. And like the X-8, the X-10 is safe to use for hobbyists and professional PC builders alike.
One reviewer who was impressed with the X-10 had this to say: “The paste is thick, yet it is easy to spread with the included spatula and stayed in place as I was spreading. I didn’t end up using the attachment it came with as it didn’t seem necessary with the spatula that it comes with. This stuff is sticky, but in a good way. It stayed where it needed to and didn’t get all over everything else.”
The above options can maintain stable operating temperatures, prevent thermal throttling, and ensure consistent performance during high-demand tasks like gaming, video editing, or even 3D rendering. It’s a vital step for PC builders, overclockers, and anyone else looking to extend the life of their pricey components.
