ARCTIC MX-7 vs Corsair XTM70 Extreme Performance Thermal Paste

Price Comparison

When considering price, the ARCTIC MX-7 is significantly more affordable at £7.29, while the Corsair XTM70 is priced at £14.99. This makes the ARCTIC paste nearly half the cost of Corsair's offering. For budget-conscious consumers or those looking to purchase thermal paste for multiple applications, the ARCTIC MX-7 presents a compelling choice without sacrificing quality. The price difference of £7.70 could be a deciding factor for many, especially given that both products aim to deliver high thermal performance.

Thermal Performance

The ARCTIC MX-7 claims next-level thermal performance due to its dense and highly viscous consistency, boasting a high filler content that ensures exceptional heat transfer. This specific formulation is designed to maintain long-term stability under thermal cycles, which is crucial for high-performance systems. In comparison, the Corsair XTM70 is advertised as ideal for high-performance processors up to 250W TDP, effectively transferring heat between the processor and the cold plate. While both products aim for high efficiency, the MX-7's focus on consistency over long periods may offer an edge for users with heavy workloads.

Application Process

The ARCTIC MX-7 is designed for a unique application style; it cannot be spread manually, allowing for natural distribution under cooler pressure. This design helps to avoid trapping air bubbles, which can potentially hinder thermal transfer. Conversely, the Corsair XTM70 features low viscosity, enabling it to spread evenly and cleanly using the included applicator kit. This difference indicates that while the MX-7 may require a more careful application process, the XTM70 simplifies the task for users who prefer a more hands-on approach, contributing to its ease of use.

Long-Term Stability

In terms of longevity, the ARCTIC MX-7 is engineered to prevent pump-out, dry-out, or bleeding, ensuring consistent performance without the need for frequent reapplication. Its high cohesion aids in this stability, making it a reliable option for users who wish to avoid the hassle of regular maintenance. The Corsair XTM70, while effective in performance, does not specifically claim to offer the same level of long-term stability. Users focused on durability might find the ARCTIC MX-7 more appealing, particularly for systems that experience significant thermal cycling.

Safety Features

Safety is a critical consideration in thermal paste selection, and the ARCTIC MX-7 is electrically non-conductive and non-capacitive, making it safe for use with CPUs, GPUs, laptops, and consoles. This eliminates the risk of short circuits or electrical discharge, a crucial feature for those working with sensitive components. On the other hand, while the Corsair XTM70 does not specify its electrical properties, the emphasis on effective heat transfer suggests a focus on performance rather than safety features. For users prioritising safety alongside performance, the ARCTIC MX-7 stands out.

Cleaning and Preparation

The ARCTIC MX-7 includes MX Cleaner, which thoroughly removes old thermal paste and prepares surfaces for optimal performance. This added feature ensures that users can start with a clean slate, enhancing the effectiveness of the new application. The Corsair XTM70 comes with three cleaning wipes to achieve a similar purpose, but it does not mention any additional preparation products. While both products offer a way to clean surfaces, the inclusion of a dedicated cleaner with the MX-7 may provide a more comprehensive solution for users looking to maximise thermal efficiency.

Brand Reputation

When comparing the brands, ARCTIC has built a reputation for producing high-quality cooling solutions, while Corsair is well-known for its gaming and high-performance hardware. Both companies have loyal followings, but ARCTIC's focus on thermal paste and cooling products may give it an edge in this specific category. Users looking for a brand with a strong emphasis on cooling performance might lean towards the ARCTIC MX-7 due to its specialised formulation, while those invested in the Corsair ecosystem may prefer the XTM70 for compatibility and brand loyalty.

Which should you buy?

Choosing between the ARCTIC MX-7 and Corsair XTM70 comes down to specific user needs and priorities. If budget, long-term stability, and safety are your primary concerns, the ARCTIC MX-7, at £7.29, offers impressive thermal performance with added safety features and a cleaner for preparation. Conversely, if you seek ease of application with an included applicator kit and are working with high-performance components, the Corsair XTM70 at £14.99 could be the better fit. Ultimately, both thermal pastes deliver quality performance, but your decision should align with your specific requirements and preferences.
