Kryonaut 5.5 g overclocking paste

Thermal Grizzly Kryonaut TG-K-015-R-5.5g is a high-performance thermal compound formulated for extreme overclocking and critical cooling applications. The syringe contains 5.5 g of silver-grey grease with a rated thermal conductivity of 11.0 W/mK. It operates reliably across a long-term range of -150 to 130 °C and remains electrically non-conductive at 0 pS/m.

Ideal for extreme overclockers

This paste suits enthusiasts pushing CPU or GPU frequencies beyond stock limits and professionals maintaining high-density server or workstation thermal interfaces. The carrier structure resists drying up to 80 °C, preserving contact quality over time. Builders who only need a basic replacement for stock coolers or who prefer a lower-cost ceramic compound will not benefit from the premium specification.

Fits any CPU or GPU socket with standard mounting

The 5.5 g volume covers multiple applications on mainstream and high-end desktop processors as well as discrete graphics cards. No curing time is required, so the cooler can be seated immediately after spreading. The non-conductive formula eliminates the risk of short circuits if excess paste contacts surrounding components. The syringe design allows precise dispensing without additional tools.

Questions about this item

Does the 5.5 g syringe cover both a CPU and a GPU application?

The 5.5 g net weight provides enough compound for several CPU and GPU mounts, so a single syringe can handle both components.

Will the 11.0 W/mK conductivity work with an older aluminium heatsink?

Yes, the paste is compatible with aluminium and its 11.0 W/mK rating improves heat transfer even on legacy coolers.

How can I verify the paste is performing correctly after installation?

Monitor CPU and GPU temperatures under load; they should stay within the -150 to 130 °C long-term operating range and show lower peaks than before.
