Perfect for Beginners and Experienced Users Alike

Designed with both performance and convenience in mind, X-8 thermal compound is the perfect choice for everyday users, gamers and DIY PC builders alike. X-8 features a silicone oil-based carrier mixed with aluminum and zinc oxide powder. Created to enhance thermal performance in CPU and GPU cooling, X-8 is ideal for use in both air and liquid cooling systems. The well-balanced formula provides very good thermal conductivity and good resistance that makes application easy, while still offering the durability needed to resist the pump-out effect.

Durable enough To Resist Pump-Out Effect

The pump-out effect occurs when thermal paste is gradually squeezed out between the heat spreader and the CPU cooler’s base plate due to deformation from temperature changes under load. Materials like silicon and copper have different thermal expansion rates, which makes the effect more pronounced, especially with a copper cooler on a graphics chip. At lower temperatures, the pump-out effect is less severe, making X-8, with its low viscosity, ideal for CPUs with lower heat output. Signs that the thermal paste needs replacing include rising CPU temperatures and reduced clock speeds.

Application Aids

Each Polartherm thermal paste comes with an applicator and spatula, offering you three convenient application methods:

• Direct Application: Apply the paste directly to the CPU without using a spatula or applicator. The cooler's pressure will evenly spread the paste, filling microscopic gaps.
• Spatula Method: Use the included spatula to spread the paste across the CPU surface. The cooler will compress the paste, ensuring complete coverage even in the smallest areas.
• Applicator Method: Use the supplied applicator to apply a thin, even layer of paste directly onto the CPU's heat spreader. The cooler's mounting pressure will ensure all remaining gaps are completely filled.

Packaging Sizes To Fit Every Project

Polartherm thermal pastes are available in sizes ranging from 2g to 40g, making them ideal for individual upgrades or multiple builds.

For Intel Core Ultra or AMD Ryzen processors, the average application count per package size is:

• 2g = 3-4 applications
• 5g = 8-10 applications
• 10g = 18-20 applications
• 40g = 70-80 applications
