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

The Arctic MX-4 thermal paste is very great. It spreads very well and it definitely keeps my 9800X3D very cool in temps and the paste is very thick to my liking. I would definitely recommend getting this and the value of the product is great.

Works great but no different than other brands I've used

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.

Worked great and is a reliable thermal paste!

As a tech enthusiast who's constantly tweaking and upgrading my gaming rig, I've slathered on my share of thermal pastes over the years—from the cheapo generics that turn into a crusty mess after a month to the overpriced "premium" ones that barely make a dent in temps. But the ARCTIC MX-4? Holy smokes, this stuff is a revelation. I slapped it on my overclocked Intel i7-13700K and RTX 3080 during a full rebuild, and it really knocks down the heat like nothing else I've tried. Idle temps dropped from 45°C to a frosty 32°C, and under heavy load—like grinding through Cyberpunk 2077 at 4K with ray tracing maxed—I'm seeing peaks of just 72°C on the CPU instead of the old 92°C furnace. That's not just a minor improvement; it's transformed my PC from a space heater into a whisper-quiet workhorse that lets me push components harder without the fear of thermal throttling or premature wear.What I appreciate most about the MX-4 is how straightforward and foolproof it is to apply, especially for someone like me who doesn't want to spend an afternoon scraping off old paste. The 4-gram tube comes with a handy spatula for even spreading—no mess, no fuss—and the viscosity is spot-on: thick enough to stay put during assembly but smooth enough to work into a thin, uniform layer without air pockets. It's 100% non-conductive and metal-free, so even if I get a smidge on the socket pins (hey, it happens), there's zero risk of shorting out my $2,000 build. Plus, ARCTIC backs it with an eight-year durability claim, and after six months of daily abuse—gaming marathons, video rendering, and even some light crypto mining—temps are still holding steady, with no drying, cracking, or migration issues. Compared to the Noctua NT-H1 I used before, this edges it out on pure thermal performance (around 2-3°C cooler on average in my benchmarks), and at this price, it's an absolute steal for the value.Application-wise, I followed the classic "pea-sized dot" method for the CPU and a thin spread for the GPU die, letting the mounting pressure do the work. Paired with a decent Noctua cooler, it's like the paste is engineered to bridge every microscopic gap, wicking away heat with its ultra-high conductivity (8.5 W/mK, if you're into the specs). The result? Not only lower temps, but quieter fans—my Noctua NF-A12x25s are spinning at half speed now, cutting noise by 20 dB and electricity draw to boot. It's eco-friendly too, free from nasty solvents or fillers, and the tube design minimizes waste (I still have half left for future swaps).If you're building, upgrading, or just troubleshooting high temps on an aging system, don't sleep on the ARCTIC MX-4. It's not hype—it's proven performance that really knocks down the heat and keeps your rig running cool, efficient, and reliable for the long haul. I've already stocked up on extras for friends' builds, and it'll be my go-to from here on out. Five stars aren't enough; this deserves a spot in every PC builder's toolkit!
