ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors

I was very happy with how well this thermal paste performed. It was easy to apply, spread evenly, and helped keep my processor temperatures under control. The syringe provides enough paste for multiple applications, and the quality feels consistent. I liked it enough that I am coming back to purchase it again. It is reliable, affordable, and does exactly what I need it to do.

This exceeded my expectations. My laptop was overheating from old thermo paste and replaced it with this thermo paste and the temperature is now regulated to normal temperatures again. My desktop is running like new again.

No problems with this paste, my CPU temps are better than ever!

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!

My first time using thermal paste. It didn’t disappoint, my 7500x3d runs well with it.

It works great to keep my cpu cool, love it.

I've used this for years on PCs and Servers No problems yet and you can usually get it for a great price comparatively.

This thermal paste is great. It says 4g, but don't let it fool you it's a lot since you only need a little bit. I have used it on two laptops and two desktops and still have some left over in the tube. Properties are good and definitely helps move heat and the devices do run cooler. Recommended!

Good results after using it. At peak Indian summer, I applied it to both my GPU & CPU. Recorded a 3-4 degree drop in temp at idle. Gaming & other activities had very little discernable difference.

It arrived fast

Använde den på mitt gamla grafikkort. Bort med den åtta år gamla stela pastan och på med denna. Fungerar utmärkt.

I got some of this a few months after purchasing a Dell XPS 9570 with 6 core i7. The CPU would hit about 83 Degrees C under high load on all cores and with GPU running hard. After re-pasting the CPU and GPU with this stuff, I no longer hit thermal throttling of any sort. Its a great product and re-pasting took minutes, literally. What I can say is you can take this a step further and add thermal pads to the VRM's and under-volt (-190mV currently) and the system runs perfectly. Battery life when on light load has doubled, up to 9 hours with 80% screen brightness on "Better Performance" mode in Windows 10. A lot of this comes from the re-pasting with this thermal compound, I was under volting before and couldn't achieve this level of thermal headroom! Great product, large amount in the tube and frankly you could probably do about 10 laptops with the amount you get.

Nothing new here, just a good, solid thermal paste that gets the job done and performs decently, and is extremely easy to apply as it's not super thick. Used in many systems, repasted multiple GPUs and all is well.
