    • Reliable Thermal Paste with Great Performance
Size: MX-4
I’ve used ARCTIC MX-4 on several builds, and it consistently performs well. The paste is easy to apply with the included spatula and spreads evenly without much effort. After applying, my CPU temperatures dropped noticeably compared to the old paste I replaced. It doesn’t dry out too quickly, giving you enough time to work. Overall, this is a solid thermal compound I’d recommend for most PC builds. Consistency: Smooth and easy to spread. Longevity: Lasts a long time without losing effectiveness. ... show more

    • Exceptional Performance at an Unbeatable Price!
Size: MX-4
I recently purchased the Arctic MX-4 thermal paste, and I must say, it has exceeded my expectations in every way. After applying it to my CPU, I noticed a significant drop in temperatures compared to the pre-applied thermal paste I was using before. The application was straightforward, thanks to its smooth consistency, which made spreading it a breeze. What impressed me most was the value for money. For a product that performs on par with some of the leading brands, the price is incredibly reasonable. I've seen temperatures drop by about 10-15 degrees Celsius under load, which is a fantastic improvement for my gaming rig. One of the best features of the MX-4 is that it doesn’t dry out over time, ensuring long-lasting performance. I appreciate that it's non-conductive, so I have peace of mind while applying it. If you’re looking for reliable thermal paste that offers excellent performance without breaking the bank, I highly recommend Arctic MX-4. ... show more

    • Decent thermal paste
Size: MX-4
It's good. Not the best, but it works decently. Keeps an OC'd 10700kf cpu temperature in check. Not sure of longevity, it's been a few months, temps still the same. Assumingly, it does not dry out quickly.

    • Great improvement over stock compound on gaming laptop
Size: MX-4
Definite improvement with thermals. Bought this to replace the stock compound on my laptop because I had noticed the temps were really high (105°C CPU, 110°C GPU under load) so I replaced the stock thermal compound on the Ryzen 9 CPU and RTX 3060 GPU in my laptop and now under heavy load the temps are both on the high 60s. Huge improvement! ... show more
