Discover Polartherm X8 40g

Designed for convenience and performance, the Polartherm X8 uses a silicone oil-based carrier with aluminum and zinc oxide powder. Its key advantage is its low viscosity, making application incredibly simple – it often spreads effectively just from the cooler’s mounting pressure. This makes Polartherm X8 40g exceptionally user-friendly, even though applicator tools are included.

This thermal paste delivers high thermal conductivity suitable for processors with a Thermal Dissipation Power (TDP) up to 70 watts, covering popular mainstream series like Intel® Core™ i3/i5 & Core™ Ultra 3/5, and AMD Ryzen™ 3 & 5. While its lower viscosity might offer slightly less resistance to the “pump-out effect” compared to the higher-viscosity X10 over extreme long-term use on hotter chips, the Polartherm X8 40g provides reliable high durability for its intended applications. Find compatible mainstream CPUs here.

Optimized for CPU and GPU cooling in standard air and liquid cooling systems, Polartherm X8 is a versatile workhorse. Its non-electrically conductive formula (0 pS/m) ensures safety during application. This large 40g quantity is highly economical, providing enough paste for approximately 70-80 typical CPU applications, making it perfect for volume builders or extensive maintenance schedules.
