Kreatos Thermal Grease 5.0

A nano-carbon silicone paste that balances strong heat transfer with easy handling. Grey, creamy consistency that spreads cleanly and stays stable through high operating temperatures. The middle pick for makers: more conductive than the 1.8, easier to apply than the 12.3, suited to 3D-printer hot ends and high-power maker electronics.

What it is

Thermal Grease 5.0 is the mid-tier in the Kreatos thermal range. The nano-carbon-enhanced silicone formulation gives you a meaningful step up in conductivity over standard thermal compounds while staying non-conductive and easy to work with. The creamy, slightly thicker consistency makes it forgiving to apply and stable under load. This is the balanced pick for makers: 3D printer hot ends, high-power LED applications, single-board and custom maker builds, and any cooling job where you want a step up in performance without sacrificing easy handling.

Best for

• 3D printer hot ends and heater blocks
• High-power LED and maker electronics cooling
• Single-board and custom maker builds
• Maker electronics and re-pasting jobs
• Workshop equipment that runs hot
• Mid-power jobs needing a balance of performance and handling

What it does well

• 5.0 W/m·K thermal conductivity
• Nano-carbon silicone formulation
• Grey, creamy consistency for clean application
• Stable through high operating temperatures
• Non-electrically conductive
• Long-term stability without dry-out
