Thermal compound PROLIMATECH PK-1 heat sink paste 5 g (thermal grease)

PROLIMATECH PK-1 heat sink paste 5 g is a thermal compound formulated to improve heat transfer between processors, GPUs, chipsets and their heat sinks. Supplied in a small syringe-style tube, the PK-1 paste fills microscopic surface irregularities to create a thin, continuous thermal interface that reduces thermal resistance and helps maintain lower component temperatures. The formula is designed for long-term stability and low dry-out, making it suitable for regular desktop and workstation cooling applications where consistent thermal performance is required.

Advantages

PK-1 offers long-term stability and low dry-out while remaining non-electrically conductive and non-corrosive. The paste is easy to apply and requires only a small amount to achieve effective contact between the chip and heatsink. In comparative tests, the compound demonstrates competitive thermal performance versus other major brands and retains reliable heat transfer over time.

Suitable for

• CPU to heatsink interfaces in desktop and workstation systems
• GPU and graphics card cooler contacts
• Chipset and voltage regulator modules requiring thin thermal interfaces
• System maintenance, repasting and performance tuning

Key specifications

• Form: syringe/tube of thermal paste
• Net weight: 5 g
• Thermal interface type: non-electrically conductive thermal grease
• Performance characteristics: low dry-out and long-term stability
• Application thickness: formulated for thin, even spread to minimize thermal resistance

How to use

Ensure both the chip and heatsink surfaces are clean and free of old thermal material, dust and oils before application. Apply a small, pea-sized amount of PK-1 to the center of the processor or follow the thin-line method appropriate for your cooler contact area. Mount the heatsink and apply even pressure so the compound spreads into a thin, continuous layer. Remove and reapply the paste during maintenance or if thermal performance degrades; routine reapplication every 12 months is recommended to maintain optimal heat transfer.

Usage recommendations

Use sparingly — a thin, even layer provides better conduction than excessive paste. Avoid contact with exposed electronic traces. Store the syringe capped in a cool, dry place to preserve consistency and shelf life.
