POLARTHERM by Thermal Grizzly

Keep your system running smoothly with our reliable and cost-effective thermal pastes. They are the perfect choice for everyone, whether everyday users, gamers, or professionals who want to keep their systems cool, quiet, and stable under any load.

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.
