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.

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.

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.

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.

It conducts heat. It spread easily using the little included spatula. I didn't need much of the stuff, as I was merely reapplying the thermal paste after a keyboard replacement in a system that required removing the CPU heat pipe and fan and motherboard to get to the keyboard. The system is running fine after surgery. I'd buy this paste again. If anything, they could sell me half this amount of paste at 2/3 the price, and I'd have been even happier.

I’m like an old dog with her favorite bone, I still believe the MX-4 is the best thermal paste on the market for the price when dealing with older powered cpus/gpus and overheating issues. I have been using MX-4 for about the past 10+ years. Both formula and performance has not changed throughout the years making it a reliable go-to thermal (knock-on-wood) to depend on. The syringe applicator makes it easy to control the amount & spread when using your fingers to cover the chip. If you don’t trust your fingers or don’t want to get them dirty, a small blue spatula (usually wedged into the bottom of the box) is included for your convenience. Should you make a mess and leak a little, there’s no need to stress since it’s metal free or non-conductive, non-capacitive and won’t cause a short circuit. The paste has a medium viscosity that’s not too thick or thin, but more like creamy peanut butter or nutella. It’s easy to apply and you’ll notice an almost immediate improvement in lower load temperatures and performance that will last for at least 7-8 years. You should be able to get 3-4 applications from the syringe. The stuff is also durable and has a long shelf life of best before date of Jan 2032, so it won’t degrade or go bad anytime soon. If you’re like me, you’ll need to buy another tube for the next time only because you lost/misplaced the open one. LOL! Overall, it does what it’s suppose to do and does it reasonably well. It’s cheap, readily available, has a loyal fan base due to its long lasting effectiveness & cooling performance, and price/performance ratio. German engineered. 5 Stars!
