Overview of Thermal Pastes
When it comes to thermal pastes, two notable contenders are Thermal Grizzly Kryonaut and Thermal Grizzly TG Putty Advance. Kryonaut is priced at £6.95, while TG Putty Advance is significantly higher at £22.94. The primary distinction between these products lies in their intended applications and thermal conductivity capabilities. Kryonaut is designed for extreme performance with a thermal conductivity of 12.5 W/mK, making it suitable for CPUs and GPUs in demanding configurations. Conversely, TG Putty Advance is a flexible thermal putty aimed at replacing traditional thermal pads, offering versatility in bridging height differences between components.
Application Methods
The application methods for both Thermal Grizzly Kryonaut and TG Putty Advance are designed for user convenience, albeit in different contexts. Kryonaut comes with a specially designed spatula, allowing users to easily spread the paste for optimal coverage. This ensures that the thermal paste fills microscopic gaps effectively, maximising cooling performance. On the other hand, TG Putty Advance can be applied using included spatulas or by hand, although the latter requires gloves for cleanliness. The putty's flexibility allows it to fill gaps ranging from 0.2 mm to 3.0 mm, making it suitable for various components that do not have uniform heights.
Thermal Conductivity
Thermal conductivity is a crucial factor in determining thermal paste effectiveness, and here, the Thermal Grizzly Kryonaut excels with its impressive 12.5 W/mK rating. This high level of conductivity supports its use in high-performance applications, ensuring that heat dissipation is maximised. In contrast, TG Putty Advance does not specify a numerical conductivity value but is positioned as a product with multiple variants, including Basic, Advance, and Pro. The Advance variant is noted for improved thermal conductivity compared to the Basic, making it suitable for enhanced heat dissipation, though it does not reach the levels provided by Kryonaut.
Versatility in Usage
Thermal Grizzly Kryonaut offers wide compatibility, being effective for various applications involving CPUs, GPUs, and other components. This versatility makes it a go-to option for users looking for a reliable thermal paste across different hardware configurations. In comparison, TG Putty Advance is tailored specifically for GPU modifications and excels in applications where traditional thermal pads are used. Its ability to bridge height differences adds another layer of versatility, but this is largely constrained to specific scenarios rather than the broader range of uses provided by Kryonaut.
Safety Features
One of the standout features of Thermal Grizzly Kryonaut is its safety profile; it is neither electrically conductive nor capacitive. This characteristic eliminates the risks associated with short circuits or discharges during application, ensuring the protection of valuable hardware. Meanwhile, TG Putty Advance is also described as electrically non-conductive, making it safe for use in a variety of applications. Both products prioritise user safety, but Kryonaut’s risk-free application adds an extra level of assurance, particularly in situations where precision is critical.
Performance in Extreme Conditions
For users who operate in extreme conditions or require reliable performance under stress, Thermal Grizzly Kryonaut is the superior choice. Its extreme performance capabilities, marked by high thermal conductivity, make it well-suited for demanding environments, whether in gaming rigs or professional workstations. In contrast, while TG Putty Advance does offer good performance, particularly with its flexible design, it is not specifically geared towards extreme high-performance scenarios. Instead, it serves well in applications requiring a flexible thermal solution, making it less suited for those pushing their hardware to the limits.
Price Comparison
The price difference between Thermal Grizzly Kryonaut and TG Putty Advance is significant, with Kryonaut retailing at £6.95 and TG Putty Advance at £22.94. This price discrepancy may influence user choices based on budget constraints and specific application needs. While Kryonaut offers exceptional performance and value for its price, TG Putty Advance’s higher cost can be justified by its unique attributes, particularly for users needing a gap-filling solution. Therefore, budget-conscious consumers may lean towards Kryonaut for general use, while those with specific needs may consider the investment in TG Putty Advance.
Which should you buy?
Choosing between Thermal Grizzly Kryonaut and Thermal Grizzly TG Putty Advance depends largely on your specific needs and application scenarios. If you require high-performance thermal conductivity for CPUs and GPUs and value ease of application, Kryonaut is the clear winner at £6.95. However, if you are looking to replace thermal pads in GPU modifications and require a flexible solution that can bridge height differences, TG Putty Advance, priced at £22.94, may be the better option. Ultimately, each product serves a distinct purpose, making the best choice contingent on your individual cooling requirements and hardware configuration.
