Frequently Asked Questions

How many times can I repaste with the 5.55 gram tube?

This is the 5.55 gram (1.5 ml) size, the larger Kryonaut tube. Exact coverage depends on die size and how thick you spread, but it is sized for repeated CPU, GPU, and console applications rather than a single build.

Does Kryonaut work on a PS5 or Xbox?

Yes. Thermal Grizzly lists PS4, PS5, and Xbox alongside CPU and GPU as intended applications for this paste, which is why the larger syringe is popular for console teardowns.

Will it dry out over time?

Thermal Grizzly states Kryonaut does not dry out even at 80 degrees Celsius, citing its specialized structure for long-lasting performance. Real-world lifespan still depends on your mounting pressure and thermal cycling.

Do I need to buy a spreader separately?

No. The package includes a spatula designed for spreading, alongside the application syringe, so you can lay down an even layer without a separate tool.

Is this paste worth it over a cheaper option?

At $23.99 for 5.55 grams it is priced above budget compounds, but the 4.7/5 rating from 59,170 reviewers reflects broad buyer satisfaction, and it is aimed at overclocking and high-heat builds where headroom matters.
