## Summary description

Polartherm X-8 is a 40 g tube of thermal paste designed to improve heat transfer between processors, graphics chips and heatsinks. The compound provides reliable thermal conductivity for desktop CPUs, laptops, GPUs and custom cooling solutions. Use to replace old paste, reduce temperatures and maintain stable performance under load. Suitable for assembly, maintenance and overclocking.

## Long description

Polartherm X-8 40 g is a high-performance thermal paste formulated to improve heat transfer between CPUs, GPUs and heatsinks. Packaged in a 40 g tube, the compound is intended for desktop processors, laptop chips, graphics cards and custom cooling assemblies where effective thermal conductivity is required to lower junction temperatures and maintain stable operation under load.
Advantages
Polartherm X-8 offers a balanced viscosity that facilitates easy application and good surface contact without excessive running. The compound is engineered for stable thermal performance, helping to reduce operating temperatures when replacing aged or degraded thermal interface materials. With a non-curing formulation, it maintains consistent thermal conductivity over extended use and is compatible with typical metal heatsink bases and integrated cooler surfaces.
Suitable for
Desktop CPU installation and reapplication
Laptop CPU and GPU maintenance and repair
Graphics card GPU thermal interface replacement
Custom cooling loops and heatsink assembly
Overclocking setups that require improved heat transfer
Key specifications
Net weight: 40 g tube for multiple applications
Form: paste/thermal compound
Thermal performance: high-conductivity formulation suitable for CPU/GPU heat dissipation
Viscosity: medium to high viscosity for controlled spread and reduced run-off
Compatibility: suitable for metal and most heatsink contact surfaces
Stability: non-curing composition designed for long-term thermal consistency
How to use
Clean both surfaces thoroughly before application: remove old thermal paste with isopropyl alcohol and a lint-free cloth, then allow surfaces to dry. Apply a small, pea-sized or line amount of Polartherm X-8 to the center of the processor or chip, depending on the heatspreader size. Mount the heatsink or cooler evenly and secure according to the manufacturer’s instructions to spread the paste into a thin, continuous layer. For GPUs and unusual surfaces, adjust the paste quantity to ensure full coverage without overflow.
Usage recommendations
Use Polartherm X-8 in well-ventilated areas and avoid contact with electrical contacts or exposed circuitry. When replacing thermal paste, check mounting pressure and re-torque fasteners after a short run-in period. Store the tube capped at room temperature away from direct sunlight to maintain consistency.
