Wadermoon Thermalright TF8 2g thermal paste 13.8 W/mK

High-conductivity carbon paste

Wadermoon Thermalright TF8 is a 2.0g syringe of carbon-based thermal compound rated at 13.8 W/mK. The grey paste is non-electrically conductive and metal-free, so it poses no short-circuit risk if it contacts pins. It is designed for CPU and GPU interfaces on any cooler type. The supplier states durability of at least eight years without re-application.

Practical limits of the interface

The compound operates from -250 °C to 380 °C, with long-term use specified up to 300 °C. Thermal resistance is quoted below 0.01 cm²·K/W and density is 2.9 g/cm³. Because it contains no metallic particles, it remains safe on exposed electrical traces. The 2.0g volume covers multiple standard desktop sockets but may be insufficient for large server heat-spreaders or repeated reapplications.

13.8 W/mK conductivity rating

This single figure determines whether the paste meets a builder's thermal budget. At 13.8 W/mK it exceeds many mainstream compounds such as the referenced 8.5 W/mK alternative, making it suitable for overclocking and sustained high loads. Buyers who need lower thermal resistance for extreme sub-ambient cooling should verify the rating against their target delta-T.
