PTM7950 Thermal pad 40x80x0.25mm phase change thermal pad vs Thermal Grizzly TG Putty Advance - 30 Gram - Electrically Non-Conductive Thermal

Overview of the Products

The PTM7950 Thermal pad is designed for high-performance cooling applications, while the Thermal Grizzly TG Putty Advance offers a versatile solution for various components. At £19.99, the PTM7950 is more affordable than the Thermal Grizzly TG Putty Advance, which is priced at £22.94. Both products are aimed at improving thermal transfer, but they utilise different materials and applications.

Material Composition

The PTM7950 is a phase change thermal pad made from a proprietary material that exhibits high thermal conductivity of 8.5 W/mK. This makes it effective at dissipating heat, particularly in high-performance integrated circuits. In contrast, the Thermal Grizzly TG Putty Advance is an electrically non-conductive thermal putty, allowing it to fill gaps and bridge height differences ranging from 0.2 mm to 3.0 mm. The choice of material in each product impacts their application suitability, with the PTM7950 being more stable under high temperatures.

Application Process

Applying the PTM7950 is straightforward, as it comes as a pre-cut thermal pad. In addition to the pad, the package includes a Phillips screwdriver, cleaning cloth, spatula, and cleaning brush, providing a comprehensive kit for installation. On the other hand, the Thermal Grizzly TG Putty Advance requires manual application, ideally with gloves, and includes three spatulas for precise application. Each method has its benefits, but the PTM7950 offers a more user-friendly experience for those less comfortable with manual application.

Thermal Conductivity

The PTM7950 boasts a thermal conductivity of 8.5 W/mK, making it highly effective for high-performance cooling. This level of conductivity ensures efficient heat transfer, critical for demanding applications. The Thermal Grizzly TG Putty Advance does not specify an exact thermal conductivity but mentions that its Advance variant offers improved conductivity compared to its Basic variant. While both products aim to enhance cooling, the PTM7950 provides a clear numerical advantage in thermal conductivity.

Versatility in Use

The Thermal Grizzly TG Putty Advance is touted for its flexibility, as it can compensate for height differences between components, making it adaptable for a variety of uses. This makes it particularly useful for GPU modifications where traditional pads may not suffice. Conversely, the PTM7950 is specifically designed for high-performance integrated circuits, making it less versatile but highly effective in its intended applications. Users looking for a multi-purpose solution may favour the Thermal Grizzly, while those focused on performance might prefer the PTM7950.

Longevity and Reliability

The PTM7950 offers impressive longevity, withstanding 1000 hours at 150 °C and maintaining low thermal impedance, which contributes to its reliability in high-performance applications. This durability is crucial for users who require consistent performance over time. The Thermal Grizzly TG Putty Advance does not provide specific longevity metrics, focusing instead on application flexibility and performance. For long-term reliability, the PTM7950 presents a more robust option.

Cleaning and Maintenance

Cleaning the surfaces before applying either product is essential, but the PTM7950 simplifies this process with included cleaning tools. The Thermal Grizzly TG Putty Advance advises thorough cleaning and degreasing before application, which may require additional effort from users. The PTM7950's included cleaning brush and cloth enhance convenience, making it more appealing for those who prefer an easier maintenance routine.

Which should you buy?

Choosing between the PTM7950 Thermal pad and the Thermal Grizzly TG Putty Advance ultimately depends on your specific needs. If you require a high-performance solution with superior thermal conductivity and ease of application, the PTM7950 at £19.99 is an excellent choice. However, if you need a versatile thermal paste that can adapt to varying component heights and offers flexibility in application, the Thermal Grizzly TG Putty Advance at £22.94 might be the better option. Take into account the specific requirements of your setup and the benefits of each product to make the best decision for your cooling needs.
