Features

  • CONSISTENT QUALITY: Our thermal paste packaging design has evolved over time, but the formula has remained the same, ensuring reliable performance.
  • 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
  • HIGH DURABILITY: In contrast to metal and silicon thermal compound, the MX-4 does not compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years
  • EASY TO APPLY: With an ideal consistency, the MX-4 is very easy to use, even for beginners

Description

ARCTIC, a leading manufacturer of PC coolers and components, initiated and continues to shape the trend towards quiet cooling systems. 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. 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. 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. 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.

  • Excellent thermal paste, buying it again
I was very happy with how well this thermal paste performed. It was easy to apply, spread evenly, and helped keep my processor temperatures under control. The syringe provides enough paste for multiple applications, and the quality feels consistent. I liked it enough that I am coming back to purchase it again. It is reliable, affordable, and does exactly what I need it to do. ... show more

  • Good quality paste
This thermal paste is great. It says 4g, but don't let it fool you it's a lot since you only need a little bit. I have used it on two laptops and two desktops and still have some left over in the tube. Properties are good and definitely helps move heat and the devices do run cooler. Recommended!

  • New Paste was very needed
Thermal paste was effective and fixed my overheating issue with this old ps4 I had laying around, It's no longer a "jet engine" the teardown was simply enough :D Also price was great, cheap enough for this 1 time job and more in the future if needed

  • Excellent thermal paste!
Paired with a 280 water cooling setup, I’m getting 40C idle and 75C stress test load on an 11th gen i7. Tons of headroom for overclocking should I desire, and it keeps the machine near silent. Easy application. Spend the 50 cents on the spatula!

  • Coolest my laptop has been in the 4 years I've had it!
I never write reviews, but over the weekend one of the fans in my Dell Precision broke. While inspecting it, I saw my 2 processors with a died out layer of thermal paste, so I decided to get it. I was worried it wouldn't be enough when I saw it in person, but spread a full layer on my 2 processors with more than half to spare. My laptop has never been quieter and colder running programs that would have made it too hot to touch just last week. Such a great product, I'm so happy with it. ... show more
