Its metal-free, non-conductive formula ensures safe application without risk of short circuits. With a proven, unchanged formula trusted by professionals and hobbyists alike, MX-4 offers easy application and long-lasting performance, making it a top choice for maintaining optimal CPU and GPU temperatures. ## 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: Great product - This is a great product that sells for itself. Seller was fast and product well packaged. Review: Still among the best options. Especially for this price. - There are better options available these days versus when this first came out -- but not a lot. The Arctic Cooling MX-4 is still an incredible choice with a great price compared to the better options. One of its key selling points from the start is also that it lasts a really long time -- and that hasn't changed. A lot of the options today that perform better still don't last as long. Of course AC MX-5 does, but that costs a fair bit more. This can be a really great compromise in price/performance with much better performance than even many in this price range and there is a lot of it, so this tube will cover a lot of devices for a long time. I've lost track of how many devices I've used it on. Since I have so much I feel free to even use it on things like Raspberry Pis and such that normally you wouldn't use such high grade stuff on. ## 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 | |---------------|-------| | ASIN | B07LDJY4X2 | | Best Sellers Rank | #24 in Silicon Grease | | Brand | ARCTIC | | Brand Name | ARCTIC | | Cooler Heatsink Compatibility | Various cooler types (not specific to socket or mounting mechanism) | | Customer Reviews | 4.9 out of 5 stars 5,256 Reviews | | Global Trade Identification Number | 00872767009653, 04895213701723 | | Included Components | ARCTIC MX-4 (20 g) | | Item Dimensions L x W x H | 4.72"L x 4.72"W x 0.79"H | | Item Weight | 33 Grams | | Manufacturer | ARCTIC | | Model | ACTCP00001B | | Part Number | ACTCP00001B | | Product Dimensions | 4.72"L x 4.72"W x 0.79"H | | UPC | 872767009653 | | Unit Count | 1.0 Count | | Warranty Description | / | ## Product Details - **Brand:** ARCTIC - **Cooler Heatsink Compatibility:** Various cooler types (not specific to socket or mounting mechanism) - **Item Weight:** 33 Grams - **Manufacturer:** ARCTIC - **Product Dimensions:** 4.72"L x 4.72"W x 0.79"H ## Images ![ARCTIC MX-4 (20 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/51UwZy8qqKL.jpg) ![ARCTIC MX-4 (20 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/519Hvwq4a-L.jpg) ![ARCTIC MX-4 (20 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/61apcOjSDQL.jpg) ![ARCTIC MX-4 (20 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/51clofQ9waL.jpg) ![ARCTIC MX-4 (20 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/61eKo7ocpYL.jpg) ## Questions & Answers **Q: Is it electrically conducting, cuz someone in reviews sayibg that it is conductive?** A: No, it is not conductive thermal paste. There is no metal oxide material in MX-4. Therefore it is not electrically conductive material. **Q: I have an unopenned mx-4 20g tube that I ordered 8 years ago. Would it still be good? Thanks** A: I think as long as it hasn't been exposed to heat or froze it will most likely be okay. You could test it on a CPU and see if it flows out of the syringe like it should. If it is chunky or doesn't want to flow at all then it is probably no good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by D***S on April 28, 2026* This is a great product that sells for itself.
