Thermal Compound Thermal Grizzly Kryonaut 12.5 W/m·K 37 g

Thermal Grizzly Kryonaut is a high-performance silicone-based thermal grease formulated for demanding applications such as overclocking and critical industrial cooling. With a thermal conductivity of 12.5 W/m·K and a 37 g tube size, Kryonaut provides effective heat transfer between processors and heatsinks while remaining electrically non-conductive and resistant to drying up to 80 °C.

Advantages

Kryonaut offers excellent thermal conductivity, long-term durability without curing, and the absence of electrical conductivity. Its formulation contains nano-aluminum and zinc-oxide particles that help compensate for microscopic surface unevenness between the CPU or GPU and the heatsink. The grease is suitable for high-load scenarios and cryogenic applications referenced by its name.

Suitable for

• Overclocked CPUs and GPUs
• High-performance gaming and workstation systems
• Critical industrial cooling applications
• Environments requiring stable long-term thermal interface material

Key specifications

• Thermal conductivity: 12.5 W/m·K
• Weight: 37 g (0.037 kg tube)
• Density: 3.7 g/cm³ (as stated in summary)
• Operating temperature range: −250 °C to 350 °C
• Base: silicone-based, non-electrically conductive
• Manufacturer MPN: TG-K-100-R, EAN: 0753677507197

How to use

Clean the surfaces of the CPU/GPU and heatsink with isopropyl alcohol and a lint-free cloth. Apply a thin, even amount of Kryonaut thermal grease to the processor heat spreader — a pea-sized or thin-line application is typically sufficient depending on CPU size and socket type. Mount the heatsink and secure it according to the cooler manufacturer’s instructions to spread the compound evenly and ensure good contact.

Recommendations

Do not use Conductonaut procedures or follow warnings about aluminium compatibility for this product; Kryonaut is non-electrically conductive and suitable for common heatsink materials. Avoid applying excessive amounts of paste — more does not improve conductivity and can impede proper mounting. Replace the thermal grease when performing major maintenance or if thermal performance degrades.
