Thermal paste Thermal Grizzly Mycro Direct-Die Pro RGB V1 — transparent black, for direct-die CPU/GPU applications

Thermal Grizzly Mycro Direct-Die Pro RGB V1 — transparent black is a thermal interface compound formulated for direct-die CPU and GPU applications where the cooling surface is intended to contact the processor die directly. The paste is developed to provide a thin, thermally conductive layer between the die and the cooler in performance-focused systems, compact form factors and overclocked setups that require careful application and precise thermal coupling.

Advantages

The formulation offers a balance of thermal conductivity and stability suitable for low-gap, direct-die mounts. Its transparent black appearance helps visual alignment during application while maintaining a minimal bond thickness to reduce thermal resistance. The product is designed to remain stable under typical operating temperatures for high-performance processors and to support efficient heat transfer in situations where conventional integrated heat spreaders are not present.

Suitable for

• Direct-die mounting on desktop and workstation CPUs
• Direct-die GPU cooling solutions and custom GPU cooling projects
• High-performance builds and overclocking where thin thermal interfaces are required
• Small form factor systems with minimal gap between die and cooler

Key specifications

• Formulation: transparent black thermal compound designed for direct-die use
• Application type: direct-die (die-to-cooler) thermal interface
• Compatibility: suitable with metals and typical cooler base materials used in CPU/GPU coolers
• Thermal behavior: engineered for low bond line thickness and efficient heat transfer in tight mounting conditions
• Physical state: paste suitable for precise manual application

How to use

Prepare the die and cooler contact surface by carefully cleaning both with an appropriate solvent or isopropyl alcohol to remove oils and residues. Apply a small, controlled amount of the thermal paste directly onto the processor die and spread only as needed to achieve a thin, even layer; the goal is to minimize thickness while ensuring full coverage of the die surface. Mount the cooler according to the cooler manufacturer's instructions, applying even pressure to achieve a consistent bond line. Avoid excess paste that could overflow onto surrounding components.

Usage recommendations

Use gloves and work in a static-safe environment when handling processor dies. For best thermal results, check contact after initial assembly and retorque mounting hardware if necessary following the cooler maker’s guidelines. This product is intended for users familiar with direct-die procedures; inexperienced users should consult detailed guides or professional services to avoid damage to the processor or socket.
