Thermal grease Alphacool 13098 — heat sink compound, 17 W/m·K, 100 g

Thermal grease Alphacool 13098 is a high-conductivity heat sink compound designed to enhance thermal contact between electronic components and cooling solutions. With a rated thermal conductivity of 17 W/m·K and a density of 3.2 g/cm³, this compound fills microscopic gaps between surfaces to improve heat transfer from CPUs, GPUs, VRMs and other heat-generating components. Supplied in a 100 g package, the grease is suitable for multiple applications in desktop and server systems where consistent thermal performance is required.

Advantages

Alphacool thermal grease offers elevated thermal conductivity to reduce junction temperatures and improve thermal stability under sustained loads. Its paste-like consistency ensures good surface wetting and gap filling without hardening, maintaining long-term contact between surfaces. The 100 g supply provides enough material for repeated applications or multiple systems, and the formulation is suitable for use with typical metal heatsinks and cold plates.

Suitable for

• Improving heat transfer between CPUs and heatsinks in desktop and workstation builds
• Thermal interface between GPUs and aftermarket coolers or water-blocks
• Cooling VRMs, chipsets and power stages on motherboards and custom electronics
• Server and rack systems requiring reliable, repeatable thermal compound performance

Key specifications

• Thermal conductivity: 17 W/m·K
• Density: 3.2 g/cm³
• Form: thermal grease / paste
• Package weight: 100 g
• Compatibility: metal heatsinks, cold plates, water-block mounting surfaces

How to use

Clean both mating surfaces thoroughly to remove old compound, dust and oils before application. Apply a thin, even layer of the thermal grease to the component heat spreader or heatsink contact area—only a small amount is required to ensure effective thermal conduction. Assemble the cooler and fasten according to the manufacturer’s instructions to create even pressure and spread the compound into a thin film. Reapply whenever the cooler is removed or if thermal performance degrades over time.

Usage recommendations

For optimal results, use the thermal grease in environments with good airflow and within the operating temperature ranges of your components. Avoid excessive amounts that can cause spillage onto the motherboard; use a modest, controlled application to achieve a thin continuous layer between surfaces. Store the product in a cool, dry place and reseal the container after use to preserve consistency.
