    • Dropped my temps and was super easy to apply
Size: MX-4
I used this paste while re-seating the cooler on my gaming PC, and the difference was immediate. My CPU temps dropped about 8–10 degrees compared to the old, dried-out paste I scraped off. It spread easily with the included spatula, which made the job way less messy than trying to guess with just the tube. The consistency is smooth — not too runny, not too thick — so even if you’re not a pro at building PCs, it’s hard to mess up. I’ve had no overheating issues since applying it, and the paste doesn’t feel like it’ll dry out quickly. Honestly, for the price, it’s a no-brainer if you want something reliable and beginner-friendly. I’ll probably keep a tube of this around just in case for future builds. ... show more

    • Just what you are looking for
Size: MX-4
Easy to spread and apply, makes my cpu cooler work better. Thick enough and high quality and sticky. Compatible with any tech you will need and 10000x better than liquid metal messes.

    • Great performance, Easy application
Size: MX-4
I used the ARCTIC MX-4 while building my PC, and it performed really well. The paste spreads smoothly, especially with the included spatula, making application straightforward. My CPU temps dropped noticeably, and it feels reliable for long-term use. It’s non-conductive too, so I didn’t have to worry about safety during installation. The only minor downside is that it can be a little pricey for the small tube size, but overall, it delivers excellent thermal performance and peace of mind. ... show more

    • Perfect Replacement
Size: MX-4
This worked perfectly for my GPU. Though I would need a good amount but still ended up having a good amount left over. Spatula was also clutch. Wasn't too sticky or too water. Great value overall.

    • Easy to use and works well
Size: MX-4
I ordered this to re-seat the CPU heat sinks on two ASUS K513 laptops when I replace the batteries. The paste spreads easily and covered the CPU/heat sink interface completely. It works very well and the CPUs have run cool since the maintenance.

    • The original and best.
Size: MX-4
I've been using Arctic as my go-to thermal paste since time immemorial, and it's never disappointed. The included spreader is a great bonus, and makes chip coverage much easier and less messy. My Core i7 runs nice and quietly with this paste transferring heat to the heat sink.
