Protect Your System from the Heat Within
When building a PC or refurbishing an older one, you may want to keep some of the heat at bay. This is where thermal paste/grease or thermal compound comes in. Most tube applicators come with a small shovel to make spreading it out easier.
The purpose of this stuff is simple. You apply it between the processor and heatsink. Once applied, it transfers heat away from the CPU and into the heat sink more effectively. The heatsink can then more easily expel the heat away from your hardware. When using the CPU for gaming or other situations, this can prevent the fan from having to run as hard.
To help you discover the best thermal paste for your CPU, we have come up with our list of the 10 best thermal pastes for CPU or GPU in 2020. We hope that it helps you to make a good choice for your system.
