High-End Thermal Compound
Phobya HeGrease Extreme is a thermal interface material rated at 8.5 W/mK for CPU, GPU and chipset applications. The 3.5 g syringe targets enthusiasts who want measurable temperature drops without changing hardware. Model 31078 delivers the conductivity figure usually reserved for premium pastes.
Viscosity And Practical Use
The compound ships in a syringe with a screw-on cap that preserves unused material between applications. Its 85000 cps viscosity lets you spread a thin, even layer that minimises the gap between die and cooler. Electrically non-conductive formulation removes the risk of short circuits if paste bridges nearby components.
Upgrade From Standard Pastes
Replacing stock or generic grease with this 8.5 W/mK compound can lower peak temperatures on existing coolers. The gain is most noticeable when the original paste has dried out or was applied too thickly. Users whose thermal solution already performs within specification will see smaller returns.

Questions about this item
What thermal conductivity does the 8.5W/mK rating provide?
The 8.5W/mK thermal conductivity enables efficient heat transfer between the CPU, GPU, or chipset and the cooler, helping to lower operating temperatures in high-performance systems.
What volume does the 3.5g syringe contain, and how is the remainder kept fresh?
The syringe holds 3.5g of compound; the screw-on cap seals the unused portion to prevent drying and keep it fresh for future applications.
How do I apply the paste correctly with its 85000cps viscosity?
Apply a thin, even layer directly onto the heat source using the syringe tip; the 85000cps viscosity allows smooth spreading without excess, ensuring minimal gap between die and cooler.
