Thermal paste fills the gaps between your CPU and its heat sink, helping to transfer the heat it produces into the cooler. Changing it annually is essential, and a good quality product can really improve performance.
When it comes to finding the best thermal paste, there are a few things you should look out for. The best thermal paste will have excellent heat transferability, be easy to apply, and provide a flat layer with no gaps or bubbles. You can also look for one that is non-electrical and safe to touch.
The ARCTIC MX-6 is our top choice and offers exceptional heat transferability, while being extremely easy to apply. It ranks at the very top of every third-party benchmark we tested and is a great option for gamers and serious overclockers who want to keep their temperatures in check. It is a little more expensive than some other options on this list, but a 5 gram tube can last several years and will easily outperform cheaper alternatives. It also comes with a spatula and cleaning pads that make cleanup very easy.
Another great option from ARCTIC is the MX-4, which is a solid option for PC builders on a budget. It is also a very good alternative for those who don’t want to pay a premium for the MX-6 or other higher-end options. Like the MX-6, it is very easy to apply and provides excellent results at a great price point.
