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

I used this when I attach a small heat sink to a fan motor for my garage heater. Worked really well for the application and should add years to the fan motors life. No longer runs hot! Came with far more paste than I thought it would. Really like the applicator. Easy to use. Easy to clean up.

Used this for some maintenance work on some older gaming laptops I got, the application was easy enough after application I ran some thermal stress tests and it seems to have done its job well leaving my temps keeping steady and within good operating conditions. Itβs not super thick it spread decently, it stuck to the components enough for me to not worry about application..overall I have no complaints so far- I have little experience with thermal paste but Iβm not unhappy with the ease of application/results.

This item is amazing. Being a newbie to "building" my own PC, I quickly learned how every little detail matters. When I thought I could forgo using it, I stood corrected immediately. My processor overheated and shut the whole computer down. So I can genuinely say that it performs the way it's supposed to. A little goes a long way so it's quite easy to apply. I had to wipe some off the sides and it was easy to clean off. It is a very strong glue so once I cleaned it off, it stuck and I've had no problems. I play Sims so you know that's a LOT of time spent so I can say the performance is amazing. For the noise level, there is none. It hear absolutely nothing after the computer starts up. If you are building a PC, definitely use it. You will need it. No questions.
