## Summary description

PROLIMATECH PK-3 is a 1.5 g thermal interface compound with rated thermal conductivity of 11.2 W/m·K. Designed to improve heat transfer between CPU/GPU surfaces and heatsinks, the paste fills microscopic gaps to reduce thermal resistance. Suitable for desktop processors, graphics cards and cooling upgrades where a small tube is required.

## Long description

PROLIMATECH PK-3 is a high-performance thermal interface compound supplied in a 1.5 g tube and engineered to improve thermal contact between CPUs, GPUs and heatsinks. With a rated thermal conductivity of 11.2 W/m·K, the paste fills microscopic surface irregularities to reduce thermal resistance and improve heat transfer efficiency in compact applications where only a small quantity of thermal paste is required.
Advantages
PK-3 uses a formulation of engineered nano-particles that conform to uneven surfaces, reducing air gaps and increasing contact area between the heat source and cooling solution. Its relatively high thermal conductivity supports lower operating temperatures under load compared with generic compounds, while the small 1.5 g tube is convenient for single builds, upgrades or work on compact systems. The consistency balances ease of application with secure thermal contact after seating the cooler.
Suitable for
 Desktop CPU installations and reapplications
 Graphics card heatsink mounting or replacement
 Cooling upgrades in compact or small-form-factor systems
 Bench tests, single builds or occasional maintenance where a small tube is preferred
Key specifications
 Weight: 1.5 g tube
 Rated thermal conductivity: 11.2 W/m·K
 Formulation: nano-particle based thermal compound
 Intended application: CPU, GPU and heatsink interfaces
 Consistency: paste suitable for manual spreading or dot/line application
How to use
Clean both mating surfaces thoroughly to remove old compound, dust and oils using appropriate solvents or isopropyl alcohol and a lint-free cloth. Apply a small amount of PK-3 to the centre of the processor or chip — for most CPUs a pea-sized dot or thin line is sufficient — then mount the heatsink and fasten it according to the cooler manufacturer’s instructions to spread the compound evenly. For GPUs or irregular surfaces, apply an amount that will be fully compressed by the heatsink to avoid excess overflow. Reapply whenever you remove the cooler or after extended service intervals.
Usage recommendations
Use only the necessary amount to form a thin continuous layer between surfaces; excessive compound can reduce performance or cause cleanup issues. Store the tube capped and in a cool, dry place away from direct sunlight. Follow standard electrostatic discharge precautions when handling internal components.
