Thermal Paste Cryorig CP15 5.7 W/m·K — 4 g thermal interface compound

Cryorig CP15 thermal paste is a grey thermal interface compound with a thermal conductivity of 5.7 W/m·K supplied in a 4 g blister pack. Designed to fill microscopic gaps between processors, graphics chips and heatsinks, this low-viscosity paste improves heat transfer and helps maintain lower component temperatures. The package includes a specialized CRYO-Paste spreader sized to match common CPU widths and a single 70% isopropyl alcohol cleaning pad to prepare mating surfaces before application.

Advantages

CP15 offers a balance of thermal performance and ease of use: its low viscosity allows simple, consistent application while requiring minimal mounting pressure for optimal contact. The included spreader is dimensioned and flexible to produce an even, thin layer across typical CPU surfaces, and the supplied isopropyl alcohol pad aids in removing old paste, dust, and residue for a clean interface. The 4 g quantity is convenient for single builds, upgrades, or targeted repairs.

Suitable for

• Desktop CPUs and multi-core processors
• Discrete GPU heatsink replacement or reapplication
• Small form-factor PC builds and single-component repairs
• Other electronic components requiring thermal interface material (chipsets, voltage regulators)

Key specifications

• Thermal conductivity: 5.7 W/m·K
• Color: grey
• Net weight: 4 g
• Viscosity: low (easy spread)
• Included accessories: spreader card and 70% isopropyl alcohol cleaning pad

How to use

Clean the CPU or GPU contact surface using the supplied 70% isopropyl alcohol pad and allow it to dry. Apply a small, pea-sized amount of CP15 to the centre of the processor die or heat-spreader. Use the included spreader to evenly distribute a thin, continuous layer across the surface, avoiding excessive thickness. Refit the heatsink or cooler and secure according to the manufacturer’s mounting procedure, applying even pressure to ensure good contact. After installation, monitor temperatures during initial use to confirm proper thermal performance.

Usage recommendations

For best results, apply CP15 in a clean, dust-free environment and use the included spreader to achieve a thin, uniform layer. Use only the necessary amount — excess compound can reduce cooling efficiency. Replace thermal paste when removing or reseating a cooler, or if operating temperatures rise unexpectedly.
