## Summary description

Qoltec thermal grease featuring a thermal conductivity of 5.15 W/m·K and low thermal resistance of 0.004 °C/W in grey color. Designed for efficient heat transfer between computer processors, graphics cards, and heatsinks to prevent overheating and ensure stable system performance during intensive computing tasks.

## Long description

Qoltec Thermal grease 5.15 W/m-K Grey Thermal Paste with 0.004 °C/W Thermal Resistance is an efficient thermally conductive paste designed to ensure reliable heat transfer in computer hardware. Featuring a thermal conductivity of 5.15 W/m·K and low thermal resistance of 0.004 °C/W, this grey thermal paste effectively fills connections and micro-gaps between components and cooling systems. It helps prevent overheating and maintains stable system performance during demanding computing tasks.
Advantages
The thermal paste stands out for its high thermal conductivity combined with high electrical insulation properties. It easily fills even the smallest surface irregularities between processors and heatsink bases to optimize cooling efficiency. The formulation allows for long-term use without requiring frequent replacement, as the paste maintains its physical and thermal properties over extended periods. Additionally, the soft consistency makes application simple and straightforward for both professionals and beginners.
Suitable for
Applying between computer central processing units and cooling heatsinks
Improving heat dissipation on graphics card processors
Filling micro-gaps in various electronic cooling assemblies
Maintaining stable temperatures during intensive computing and gaming sessions
When it may not be suitable
This thermal paste is not designed for direct metal-to-metal contact applications where no heatsink or cooling fan is present. It should also be avoided in extreme industrial environments that exceed standard computer hardware operating temperatures.
Key specifications
Thermal conductivity: 5.15 W/m·K
Thermal resistance: 0.004 °C/W
Color: Grey
Quantity per pack: 1 piece
How to use
Before applying the thermal paste, ensure that the contact surfaces of the processor and the heatsink are completely clean, dry, and free from any old paste residues or dust. Apply a small amount of the paste directly onto the center of the component surface. Spread it evenly in a thin layer using a spatula or let the pressure of the mounted heatsink distribute it naturally across the micro-gaps. Secure the cooling system firmly in place and wipe away any excess paste.
What to consider before purchase
Verify the required thermal conductivity for your specific hardware cooling requirements
Check the quantity needed for your planned number of applications
Ensure compatibility with your processor and heatsink mounting mechanisms
For optimal cooling performance, store the thermal paste in a cool, dry place away from direct sunlight, and always ensure surfaces are thoroughly cleaned before each new application.
