Corsair XTM70 Extreme Performance Thermal Paste vs PTM7950 Thermal pad 40x80x0.25mm phase change thermal pad

Introduction to Thermal Solutions

When it comes to keeping your CPU or GPU cool, choosing the right thermal solution is crucial. The Corsair XTM70 Extreme Performance Thermal Paste and the PTM7950 Thermal Pad are two popular options, each with distinct features and benefits. Priced at £14.99 and £19.99 respectively, both products aim to optimise heat transfer, but their approaches and applications differ significantly.

Application Method

The Corsair XTM70 is a thermal paste that is applied directly to the surface of your CPU or GPU. It features a low viscosity that allows for easy spreading with the included applicator kit, ensuring an even and clean application. The PTM7950, on the other hand, is a phase change thermal pad that is simply placed between the component and the cooler. This difference in application method means that the XTM70 can be more tedious to apply, but it allows for a closer connection to the heat source, potentially improving thermal transfer.

Thermal Performance

In terms of thermal performance, the Corsair XTM70 is designed for high-end processors with a thermal design power (TDP) of up to 250W and more, making it suitable for demanding applications. The PTM7950 boasts a thermal conductivity rating of 8.5 W/mK, which is impressive for a thermal pad. However, the Corsair XTM70’s ability to effectively transfer heat from high-performance components may give it an edge in scenarios where maximum cooling is vital.

Longevity and Reliability

The PTM7950 thermal pad is engineered for longevity, offering superior reliability withstanding 1000 hours at 150 °C and enduring 1000 thermal cycles. This makes it a durable choice for long-term use. Meanwhile, the Corsair XTM70 also contains enough material for multiple applications, which suggests a degree of longevity but does not explicitly state its lifespan under high stress. If you’re looking for a solution that will last through many uses, the PTM7950 may be more appealing.

Cleaning and Maintenance

The Corsair XTM70 comes with three cleaning wipes, making it easier to remove old thermal paste before application. This feature can be particularly handy for users who frequently upgrade their systems or need to replace thermal paste. The PTM7950, while not requiring frequent replacements, does not offer specific cleaning tools. Therefore, if regular maintenance is a part of your routine, the Corsair XTM70 provides a more comprehensive cleaning solution.

Included Accessories

When it comes to included accessories, the Corsair XTM70 offers an applicator kit alongside cleaning wipes, promoting ease of use. The PTM7950, in contrast, includes a Phillips screwdriver, a cleaning cloth, a spatula, and a cleaning brush. This assortment of tools is beneficial for preparing your system and installing the thermal pad. Depending on your needs, the choice of accessories might influence your decision: if you prefer a straightforward paste application, Corsair is the way to go; if you need tools for a broader installation, the PTM7950 is better equipped.

Price Comparison

The Corsair XTM70 is priced at £14.99, making it a more affordable option compared to the PTM7950, which retails for £19.99. This difference of £5 may seem modest, but it could sway budget-conscious buyers who are looking for effective cooling solutions without overspending. However, it’s important to consider the features each product offers for the price; the PTM7950's durability and included accessories may justify its higher cost for some users.

Which should you buy?

Choosing between the Corsair XTM70 Extreme Performance Thermal Paste and the PTM7950 Thermal Pad ultimately depends on your specific needs and preferences. If you require maximum thermal transfer for high-performance processors and prefer a paste application, the Corsair XTM70 is your best bet. However, if you’re looking for a long-lasting, easy-to-install solution with a range of included tools, the PTM7950 may be the superior choice. Both products provide effective cooling, but their unique features cater to different types of users in the overheating battle.
