Thermal paste PROLIMATECH PK-Zero 8 W/m·K — 150 g thermal compound

PROLIMATECH PK-Zero 8 W/m·K — 150 g is a thermal compound formulated to improve heat transfer between processors and heatsinks. With a thermal conductivity of 8 W/m·K and a net weight of 150 g, this paste fills microscopic surface irregularities to create a more efficient thermal contact. The compound is non-conductive electrically, has low dry-out characteristics and does not require a burn-in period, making it suitable for initial assembly and repeated reapplications.

Advantages

The PK-Zero offers high thermal conductivity for its price class while remaining easy to apply. Its nanoparticle-enhanced formula increases contact area at the microscopic level, improving heat dissipation without posing electrical conductivity risks. The product has a stable density that supports consistent spreadability and a long service life with low tendency to dry out, enabling multiple reuses from a single 150 g package.

Suitable for

• Thermal interface between CPUs and air or liquid coolers
• GPU cooling pads and heatsink contact surfaces
• High-volume assembly or repeated maintenance where a larger quantity is needed
• Desktop and server systems requiring reliable thermal transfer at budget cost

Key specifications

• Thermal conductivity: 8 W/m·K
• Net weight: 150 g
• Density: 2.6 g/cm³
• Electrical behavior: non-conductive
• Formulation: nanoparticle-enhanced paste

How to use

Clean the CPU/GPU and heatsink contact surfaces with isopropyl alcohol and a lint-free cloth to remove old compound, dust and oils. Apply a small, even amount of PK-Zero to the center of the processor or onto the heatsink surface, then mount the cooler and secure it according to the manufacturer's instructions to spread the paste evenly. For larger surfaces or reapplications, use appropriate amounts while avoiding excess that could squeeze out beyond the contact area. Allow normal operating cycles; no burn-in period is required before the compound reaches effective thermal performance.

Recommendations

Store the thermal paste in a cool, dry place and keep the container tightly closed when not in use. Use protective gloves if preferred and avoid contact with skin or eyes. For best results, apply a thin, even layer and replace the compound during major cooling upgrades or if thermal performance degrades. Not electrically conductive, but avoid contaminating other electronic components when applying.
