Product Information
Full details
The Polartherm X-8 Thermal Paste is a high-performance thermal interface material designed for professional system builders, workshops, and PC enthusiasts who require a large-volume supply for multiple cooling applications. It provides excellent thermal conductivity to bridge the microscopic gaps between your processor and cooling solution, ensuring stable temperatures for both air and water-cooled CPUs and GPUs. While it offers superior long-term performance due to its pump-out resistance, the large 40g tube format is primarily suited for frequent users rather than a one-time casual upgrade.

Extended Product Information
FAQs
Is this paste electrically conductive?
Polartherm X-8 is designed to be a non-conductive thermal interface material, making it safe for standard PC components.
Can I use this on both my CPU and GPU?
Yes, this paste is optimized for both desktop CPU heat spreaders and bare-die GPU surfaces.
How should I clean off the old thermal paste?
Use high-percentage isopropyl alcohol (90% or higher) and a lint-free cloth or paper towel for the best results.
How long will a 40g tube last?
For an average user, 40g is enough for dozens of applications, making it perfect for long-term storage or frequent build cycles.
Do I need to spread the paste manually?
While the pressure of the cooler is usually enough to spread the paste, the included spatula allows for a manual 'spread method' if you prefer full surface coverage.
Troubleshooting
Temperatures remain high after application
Ensure that the cooler mounting pressure is even and that the cooler is fully locked into position.
Paste is difficult to spread
Ensure the CPU is at room temperature. The paste may be firmer in very cold environments; you can warm the tube in your hand for a minute before application.
Pros and Cons
Pros
- Generous 40g volume provides excellent value for frequent system builders
- Resistant to pump-out, ensuring consistent performance over time
- Includes professional-grade spatula and applicator tools
- Suitable for high-demand environments including water cooling loops
- Uniform consistency makes for easy, mess-free application
Cons
- The 40g tube may be excessive for a single desktop PC build
- Requires proper cleanup of old paste before application
- Not intended for non-thermal computing applications
Setup, Compatibility & Care
To ensure peak performance, follow these steps during your installation:
- Surface Preparation: Always use an isopropyl alcohol wipe to remove any legacy thermal paste from the CPU and the cooler base until both surfaces are clean and shiny.
- Application: Apply the Polartherm X-8 to the center of the processor heat spreader.
- Mounting: Secure your cooler with even pressure. Avoid lifting the cooler once it has made contact with the paste to prevent air bubbles.
- Care: Store the 40g tube with the cap tightly secured in a cool, dry place to maintain the viscosity of the compound for future use.
Compatibility: This product is compatible with all desktop CPUs and GPUs that utilize a heat spreader interface.
