Thermal Grizzly Kryonaut vs PTM7950 Thermal pad 40x80x0.25mm phase change thermal pad

Overview of Thermal Solutions

When it comes to cooling your computer components, selecting the right thermal solution is crucial. In this comparison, we will examine the Thermal Grizzly Kryonaut and the PTM7950 Thermal Pad, both popular options in the cooling market. While the Kryonaut is a thermal paste, the PTM7950 is a thermal pad, and each product has unique characteristics that cater to different needs. The Kryonaut is priced at £6.95, while the PTM7950 comes in at a higher price of £19.99.

Performance Comparison

In terms of thermal conductivity, the Thermal Grizzly Kryonaut boasts an impressive rating of 12.5 W/mK, making it an excellent choice for high-performance applications. This high conductivity ensures that heat is efficiently transferred away from critical components, which is especially vital for demanding CPUs and GPUs. On the other hand, the PTM7950 Thermal Pad has a thermal conductivity of 8.5 W/mK, which, while still effective, is lower than that of the Kryonaut. Thus, for extreme performance needs, the Kryonaut outshines the PTM7950.

Application Ease

When it comes to ease of application, the Thermal Grizzly Kryonaut stands out with its specially designed spatula, allowing users to spread the thermal paste evenly. This feature ensures optimal coverage over the component surface, maximising cooling performance. The optimal viscosity of the Kryonaut also aids in filling microscopic gaps effectively. Conversely, the PTM7950 Thermal Pad, while packaged with a spatula and cleaning tools, requires precise placement due to its rigid structure. For users who prefer a fuss-free application, the Kryonaut may be the better choice.

Compatibility

The Thermal Grizzly Kryonaut is marketed as being widely compatible with a variety of components, including CPUs and GPUs. This versatility makes it suitable for a range of cooling requirements, whether for personal computers or industrial applications. In contrast, the PTM7950 Thermal Pad is specifically designed for integrated circuit devices, making it ideal for certain applications but potentially limiting in broader uses. If you need a product that works across multiple components, the Kryonaut is likely the more suitable option.

Longevity and Reliability

Longevity is a crucial factor when choosing between thermal solutions. The PTM7950 Thermal Pad is designed to last longer than conventional thermal pads, withstanding 1000 hours at 150 °C and 1000 thermal cycles. This reliability makes it a solid choice for environments where heat management is critical. On the other hand, while the Thermal Grizzly Kryonaut is reliable, specific longevity metrics are not provided. Therefore, if longevity under extreme conditions is a priority, the PTM7950 has a clear advantage.

Thermal Impedance

The PTM7950 Thermal Pad offers low thermal impedance of less than 0.04 °Ccm²/W without washers, which contributes to its efficiency in heat transfer. This property is particularly beneficial in high-performance settings where every degree counts. While the Thermal Grizzly Kryonaut does not provide a similar metric, its high thermal conductivity suggests that it also performs effectively in reducing heat buildup. However, if thermal impedance is a primary concern, the PTM7950 stands out with its quantified lower value.

Included Accessories

Both the Thermal Grizzly Kryonaut and the PTM7950 Thermal Pad come with useful accessories to aid application. The Kryonaut includes a spatula specifically designed for easy application, ensuring that users can achieve an even coat. The PTM7950 package is more comprehensive, including a Phillips screwdriver, cleaning cloth, spatula, and cleaning brush. This additional toolkit may be more appealing for users looking for a complete setup. If having extra tools is essential, the PTM7950 offers more in this regard.

Price Consideration

Price is a significant factor for many consumers. The Thermal Grizzly Kryonaut is available for £6.95, making it a cost-effective option for those seeking high-performance thermal paste. In contrast, the PTM7950 Thermal Pad is priced at £19.99, which may deter budget-conscious buyers. While the PTM7950 offers additional reliability and features, the price difference of £13.04 could influence purchasing decisions, especially for those who do not require the advanced capabilities of a thermal pad.

Which should you buy?

In conclusion, the choice between the Thermal Grizzly Kryonaut and the PTM7950 Thermal Pad largely depends on your specific cooling needs. If maximum thermal conductivity and ease of application are your priorities, the Kryonaut is a clear winner with its 12.5 W/mK rating and user-friendly spatula. However, if you are looking for longevity and reliability in extreme conditions, the PTM7950 Thermal Pad, despite its higher price, offers advantages such as low thermal impedance and a comprehensive accessory package. Ultimately, your choice should reflect your cooling requirements, budget, and preferences in application methods.
