Polartherm X10 40g Thermal Paste

Polartherm X10 Thermal Paste (40g)

Keep your high-performance system cool and stable with Polartherm X10 40g thermal paste. This large 40g package offers excellent value and is designed for experienced mainstream PC users, system integrators, and frequent builders. Born from German innovation, X10 features an improved high-viscosity formula for excellent thermal conductivity and outstanding long-term durability, resisting the pump-out effect common with high-heat components. Furthermore, application is made easy with the included tools.

Discover Polartherm X10 40g

Experience the next level of cooling with the X10 thermal compound. Its advanced silicone-based formula contains a higher concentration of aluminum and zinc oxide powder compared to the X-8, resulting in very high thermal conductivity suitable for processors with TDPs over 70 watts. Consequently, this makes Polartherm X10 40g ideal for demanding CPUs like Intel® Core™ i7/i9 & Core™ Ultra 7/9 series, as well as AMD Ryzen™ 7 & 9 series processors.

A significant advantage of X10 is its long-term stability due to its relatively high viscosity. This formulation minimizes the “pump-out effect,” where paste is gradually squeezed out from between the CPU/GPU heat spreader and the cooler base due to thermal cycling. This ensures consistent, reliable cooling performance over time, especially critical for high-heat components. Moreover, despite its viscosity, application is user-friendly with the included PT Spatula and Applicator, allowing for thin, even layers using various methods. Explore compatible high-performance CPU coolers here.

Optimized for diverse applications including CPUs, GPUs, notebooks, and ICs, Polartherm X10 40g excels in both air and water-cooled systems. Its non-electrically conductive nature (0 pS/m) guarantees safety during application. This generous 40g size provides exceptional value, containing enough paste for approximately 70-80 typical CPU applications, making it perfect for system builders or users maintaining multiple machines.
