Thermal paste is vital to keep your CPU within an optimal temperature range. Although modern processors such as the AMD Ryzen 9 9950X are designed to run at up to 95C where the chip will scale back power, it’s best to keep it as cool as possible to improve longevity. But which thermal paste is best for this 16-core processor? That’s where our collection of the best thermal paste comes into play and is a good place to start.

Any reputable branded paste will work well enough, so long as you have ample cooling for the CPU. The AMD Ryzen 9 9950X could be cooled with a premium high-end air cooler, though I’d recommend considering an AIO liquid cooler with a 360mm radiator, or the largest your PC case would allow.
Any of these recommended thermal pastes will keep the Ryzen 9 9950X running as designed by AMD. The Arctic MX-6 offers excellent thermal performance for the price. At less than $10, you won’t have any trouble running the 9950X at boost speeds for longer periods with the best CPU cooling.

Keeping your CPU cool is essential if you want a working PC. If you want some of the best thermal paste around, here are your options.
Why use thermal paste with the AMD Ryzen 9 9950X?
Thermal paste is a vital component of any PC build or upgrade. When working with the CPU, you must ensure thermal paste is applied to facilitate the transfer of heat between the integrated heat spreader (IHS) on the CPU and the baseplate of the CPU cooler. Manufacturing defects and general wear can cause the two surfaces to form a compromised seal, which is where thermal paste comes in, filling the gaps, which helps move heat away from the CPU.
