High-performance thermal paste is an essential component for the efficient operation of a CPU. The primary function of the TIM is to transfer heat between the CPU and the cooling system, reducing the temperature of the CPU. In addition to the transfer of heat, TIMs also provide a seal to prevent moisture and contaminants from leaking in and damaging the CPU.
Despite being a simple, yet important part of a computer build, the process of applying a TIM can be confusing for newcomers. There are many different types of TIMs on the market, all of which perform differently. Most are sold in a tube with an applicator, but some are available as sachets or even in stencil kits to take the guesswork out of application and reduce plastic waste. Each sachet of Arctic MX-6 provides the tried and tested ‘pea sized’ amount to ensure adequate coverage for standard desktop CPU IHSs. The packaging is designed to reduce the amount of plastic, and is supplied in a recycled card envelope with coated foil sachets (no applicator included).
Some TIMs are electrically conductive, such as those that use silver particles (like Arctic Silver 5), while others are not. Pastes that conduct electricity should only be used on dies with a heat spreader and no exposed components nearby. Otherwise, the metal particles may run and short-circuit the components.
Some TIMs are designed to be resistant to drying out, like the Thermal Grizzly Kyronaut. These types of TIMs can outperform traditional pastes in some cases, but they may not be suitable for all builds. For example, if your CPU is in a small cooler that’s not designed to be air-cooled you should stick with a traditional thermal paste.Non-conductive thermal paste
