Thermal Putty Alphacool Apex X1 50 g — Alphacool thermal interface compound

Alphacool Apex X1 Thermal Putty 50 g is a thermal interface compound formulated to improve heat transfer between electronic components and cooling solutions. Supplied in a 50 g container with a paste-like consistency, this thermal putty fills microscopic gaps and uneven surfaces on CPUs, GPUs, heatsinks and water-cooling blocks to reduce thermal resistance and support stable operating temperatures during heavy loads.

Advantages

The Alphacool Apex X1 offers a balance of thermal conductivity and ease of application, making it suitable for both initial assembly and maintenance. Its paste-like texture enables precise placement and good surface conformity without hardening, which facilitates rework and component replacement. The product is non-abrasive and designed to maintain consistent contact between mating surfaces, supporting more efficient cooling in air- and liquid-cooled systems.

Suitable for

• Applying between CPU heat spreaders and cooler bases
• Improving thermal contact on GPU dies and graphics card coolers
• Filling interface gaps on heatsinks and water-cooling blocks
• System maintenance, repasting and component upgrades

Key specifications

• Form: paste-like thermal putty
• Net weight: 50 g
• Compatibility: suitable for CPU, GPU, heatsink and water block interfaces
• Application temperature range: designed for typical PC operating temperatures (ambient to elevated load conditions)
• Reworkability: remains workable for removal and reapplication during maintenance

How to use

Clean both mating surfaces thoroughly to remove old compound, dust and oils before application. Apply a thin, even layer of Alphacool Apex X1 to the component surface or cooler base, ensuring sufficient coverage without excessive overflow. Assemble the cooler and apply even mounting pressure to spread the putty and establish full contact. After installation, monitor temperatures during initial operation to confirm proper thermal performance. For removal, gently separate components and clean residual putty with an appropriate solvent or isopropyl alcohol.

Usage recommendations

Use a small amount to avoid over-application; excessive compound can impede mounting or contact. Store the container sealed and in a cool, dry place to preserve consistency. If the product will be used on liquid-cooling blocks, ensure surfaces are fully clean and dry to prevent contamination of the cooling loop. Follow standard electrostatic discharge (ESD) precautions when working with electronic components.
