Thermal paste is one of the most critical components of any PC build. It's what ensures direct even contact between the CPU and cooling application, but not all thermal paste is created equal. Here are some of our favorites.
Arctic MX-4 (opens in new tab)
The MX-4 by Arctic is one of the better choices for most PC builders and is recommended by many. Not only is it affordable, but it also performs exceptionally well even in enthusiast applications. It's easy to apply, remove, and helps keep your CPU well cooled.
Thermal Grizzly Hydronaut (opens in new tab)
Thermal Grizzly's Hydronaut is designed for more severe applications, including water-cooled systems. If you happen to be an enthusiast and need some excellent performing paste, this is the one for you thanks to its optimal heat transfer capabilities.

When you're ready to do some tinkering to get the absolute best performance out of your CPU, the Kryonaut by Thermal Grizzly is an excellent thermal paste. Note that this price is for the 1g tube. It's best suited for applications that involve overclocking and sub-zero performance.
