Trusted by professionals and enthusiasts alike, it ensures efficient heat transfer, protects hardware from electrical damage, and offers easy application with guaranteed authenticity. ## Description Product description High thermal conductivity The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC‘s MX-4 thermal paste is composed of carbon microparticles which fill these cavities. This leads to extremely high thermal conductivity, ensuring that heat is dissipated quickly and efficiently from the CPU or GPU. With its outstanding performance, the MX-4 is not only an excellent choice for overclockers and enthusiasts, but also for other sapplications that require thermal transmission. Easy application Thanks to its consistency, MX-4 is easy to apply, even for beginners. The video in the picture gallery demonstrates the application technique to avoid air pockets between processors and coolers. Secure usage In contrast to pastes based on metal oxides or liquid metal, ARCTIC’s MX-4 is metal-free and not electrically conductive. This eliminates the risk of short circuiting, and eliminates the need to worry about corrosion damage to the radiator floor caused by liquid metal. 100 % original through Authenticity Check To ensure that your paste is genuine, there is the ARCTIC Authenticity Check. This allows every product to be reliably verified. A counterfeit offers neither the performance nor the durability of the original ARCTIC pastes. Technical Specifications Density: 2.50 g/cm³ Viscosity: 31,600 Poise Volume Resistivity: 3.8 x 10¹³ Ω-cm Continuous Use Temperature: -50~150 °C Colour: Grey Review: PERFECT - Fantastic value. Great to have around for refurbishing laptops. I use this stuff on my own desktop computer and was happy to find an "industrial size". Can't recommend it enough for everyday mid-range processors. Makes older i5s and i7s totally usable in 2026, which I love since the average laptop's build quality just gets worse and worse as time goes on. Review: Excellent thermal paste - Arctic Cooling MX-4 is an excellent choice for most users due to its reliability, good thermal conductivity (8.5 W/mK), and a convenient consistency that does not dry out over time and is easy to apply. It significantly reduces CPU temperatures, as confirmed by numerous user reviews, and is suitable for high-power systems and even overclocking. Overall, it's a versatile thermal paste that deserves a high recommendation. ## Features - WELL PROVEN QUALITY: The design of our thermal paste packagings has changed several times, the formula of the composition has remained unchanged, so our MX pastes have stood for high quality - EXCELLENT PERFORMANCE: ARCTIC MX-4 thermal paste is made of carbon microparticles, guaranteeing extremely high thermal conductivity. This ensures that heat from the CPU/GPU is dissipated quickly & efficiently - SAFE APPLICATION: The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards - 100 % ORIGINAL THROUGH AUTHENTICITY CHECK: Through our Authenticity Check, it is possible to verify the authenticity of every single product - EASY TO APPLY: With an ideal consistency, the MX-4 is very easy to use, even for beginners ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #30 in Silicon Grease | | Customer Reviews | 4.8 out of 5 stars 1,323 Reviews | ## Images ![MX-4 (45 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Image 1](https://m.media-amazon.com/images/I/51H6L6vY3qL.jpg) ![MX-4 (45 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Image 2](https://m.media-amazon.com/images/I/616SjFXLvaL.jpg) ![MX-4 (45 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Image 3](https://m.media-amazon.com/images/I/61WTAsGQ5nL.jpg) ![MX-4 (45 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Image 4](https://m.media-amazon.com/images/I/61eKo7ocpYL.jpg) ![MX-4 (45 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - Image 5](https://m.media-amazon.com/images/I/61hRt2VUslL.jpg) ## Questions & Answers **Q: what is the number of Thermal Conductivity , Thermal resistance and density ?** A: It's listed on the bottom of the page. Specific Gravity: 2.50 g/cm3 Thermal Conductivity: 8.5 W/(mK) Volume Resistivity: 3.8 x10^13 ohm-cm **Q: I know this good for ps4 but can pad be good too and what size.** A: There's enough in it that it should be good for any size CPU. **Q: La pasta termica tiene fecha de caducidad o de vencimiento?** A: hola amigo, mientras tengas la pasta a temperatura ambiente y en su caja o su defecto en en lugar oscuro te puede durar muchos años, en la caja de igual forma no generan fecha de vencimiento, y la verdad te la recomiendo 100% la he utilizado en todos mis portátiles y en dos consolas ps3 y si nota su mejora ante recalentamientos ni los video juegos ni los portátiles se me apagan **Q: Will this product work on a vertical surface? Or, once it heats up will it drip?** A: Yes, this will work just fine in a vertical surface. Most CPU's in PC's are mounted vertical and that's what this is designed for. ## Customer Reviews ### ⭐⭐⭐⭐⭐ PERFECT *by T***I on January 22, 2026* Fantastic value.
