ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC, PS4, Xbox), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive, Non-capacitive

Needed this for a PS4 and Nintendo Switch thermal paste replacement. No issues whatsoever; in fact, this is probably higher quality paste than what the factory uses. The Switch uses paste in multiple spots and layers, no issues with adhesion between the various metals. Arctic is the name brand in paste and I am satisfied with the durability and versatility, as well as the ease of application. Highly recommend this paste.

Applying the “ARCTIC MX-4 thermal paste” immediately showed why it’s so highly regarded in the PC repair world. The application was smooth, clean, and easy to control, making the entire process feel precise rather than messy. Once everything was back together, temperatures stabilized quickly, and the system ran noticeably cooler under load. That kind of reliable performance is exactly what you want when working with CPUs or GPUs. What impressed me most is how dependable and straightforward this product is—no gimmicks, just solid thermal transfer and long-lasting results. For anyone maintaining computers, gaming systems, or upgrading hardware, ARCTIC MX-4 proves itself as a trustworthy addition to the toolbox.

No problem applying it and the computer is running find good product no heat spikes

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!

Used this for some maintenance work on some older gaming laptops I got, the application was easy enough after application I ran some thermal stress tests and it seems to have done its job well leaving my temps keeping steady and within good operating conditions. It’s not super thick it spread decently, it stuck to the components enough for me to not worry about application..overall I have no complaints so far- I have little experience with thermal paste but I’m not unhappy with the ease of application/results.

Good quality with a generous amount of paste

I just used this Artic MX-4 in an 11 year old HP Pavilion Elite PC M9350f and it's back up and running! (it had not been running for about three years). I gave this PC (new) to my mother in 2008 and it's a great all-around PC, but four years later (2012), a relative talked her into spending around $2000 on an iMac (less RAM, HD, processor, etc), so this HP PC has been sitting a lot. I've asked her repeatedly if she wants me to take it back and she hasn't answered me. So there it sits, not in use, since 2012. The "Apple genius" relative talked her into an iMac with half the RAM and slower processor because she kept complaining that "this computer is too slow", when I had the sense enough to know the problem wasn't the HP computer, it was that she was using dial-up for her internet & I repeatedly informed her of this! Apparently our relative did not have the same good sense. They push Apple products on her because that's what they use, yet her 2012 iMac's CD drive has since died (about two years ago) and some of the monitor's lighting isn't functioning so 1/2 screen is dimmer than the other half...that's been about three years. About two years ago, I powered up the HP at her home to make sure it got some updates (she now has cable modem, but it's really slow, about 3mbps), I noticed the PC didn't stay powered up. I thought the heat-sink had died because the PC shut down within a minute of starting to heat up. I briefly opened up the box to look at the heatsink and it almost looked slightly corroded(?) ….the home is located near the beach so I'm not sure it that could be the problem. Nothing else inside the box looked affected. I figured I would need to clean or replace the heatsink, but it would need to be a "pull" from another similar era PC. Either way, I still needed thermal compound. I recently found an OEM heatsink pull to use if needed (just in case the original heatsink was indeed bad), and ordered the Arctic MX-4 based on many positive reviews. I decided to first try to clean the OEM heatsink (& processor) and use this Thermal paste before either swapping the heatsinks, especially since the OEM heatsink looks pretty beefy (photos attached - the center photo shows the bottom of the copper-color heatsink to the left in the photo with the top of the processor in the center of the photo). When I removed the heatsink, I could see that the OEM paste was completely dried up (not surprised considering the age). After thoroughly cleaning the top of the processor and the bottom of the original heatsink with alcohol, I brushed all the areas of the heatsink I could access, with a stiff bristle brush because of possible moisture/corrosion (the rest of the PC looked fine, other than a bit of dust)... I placed about a pea-sized dollup of MX-4 paste on the processor, then promptly re-installed the original heatsink, clamping it down tightly & making sure no paste had oozed out (a pea-sized dollup is all you need) & powered up the PC. It booted up, opened windows, proceeded to do over 200 updates (Windows 7 Home Prem) and kept running. We let it run several hours since it had not been run in a few years. I'd say this paste is pretty amazing to be able resurrect an "old" workhorse HP. Would similar pastes do the same, probably, but I'll monitor how well it lasts and prevents the processor from overheating. I'm typing this review on my HP that's the same age & very similar model, except it has an Intel processor (my PC is an HP Pavilion Elite M9200t). If my PC starts overheating and shutting off, I'll definitely do the same procedure as I did with my mother's HP. I'll be able to get several applications out of the syringe of paste.

It worth every penny. I have a computer with the same thermal paste of this brand for a long time and it still working in a normal temperature.

Bardzo dobra pasta. Spełnia swoje zadanie do procesora Intel i5

Ótimo produto, era esperado que reduzisse cerca de 20 graus da minha CPU do notebook no máximo e reduziu 27, fiz um mod num VAIO de 2011 de 4 GB de RAM que agora tem 16, e está voando veio no prazo e bem embalado. Vou aproveitar o que sobrou e trocar pasta antiga para aplicar num xbox 360 e em um One, Nota 10!

Ho scelto l’ARCTIC MX-4 perché avevo bisogno di una pasta termica efficace per migliorare il raffreddamento del mio PC da gaming e, all’occorrenza, di una soluzione sicura anche per altre CPU o GPU. Prima impressione La confezione è compatta e ben protetta, con il tubetto facile da usare. La pasta ha una consistenza densa ma morbida, che permette un’applicazione uniforme senza difficoltà. Il fatto che sia non conduttiva dà subito un senso di sicurezza durante l’installazione. Uso nella vita quotidiana L’ho applicata sul mio processore e sui dissipatori della GPU: già dai primi test si nota una riduzione delle temperature di alcuni gradi rispetto alla pasta termica precedente. La pasta mantiene la sua consistenza nel tempo e non secca facilmente, il che la rende pratica per aggiornamenti o manutenzioni future. Funziona bene anche su console come PS4 senza alcun rischio di cortocircuito. Cosa funziona bene Conducibilità termica molto alta, migliora effettivamente il raffreddamento. Facile da applicare grazie alla consistenza ottimale. Lunga durata, non si asciuga rapidamente. Non conduttiva, quindi sicura anche per applicazioni delicate. Compatibile con CPU, GPU e persino console come PS4. Cosa convince meno Non è inclusa una spatola di precisione, quindi serve un piccolo accessorio per stendere al meglio. Tubetto da 4 g sufficiente per alcune applicazioni ma potrebbe non bastare per più build o aggiornamenti frequenti. Prezzo leggermente superiore ad alcune paste termiche base, ma giustificato dalla qualità. Conclusione L’ARCTIC MX-4 è una pasta termica eccellente per chi vuole mantenere CPU e GPU a temperature ottimali senza rischi. Affidabile, durevole e sicura, rappresenta un’ottima scelta sia per PC da gaming che per console.

I’ve used this on everything: own laptops, own PCs, friends and family's machines, and even on people that are coming to me to repair their machines. It never misses. Nobody complained, no returns due to heating issues. Why 5-Star? First, foolproof application. The consistency is perfect not too runny, not too thick. It spreads evenly without making a mess, which is a lifesaver for beginners and pros alike. However, please pay attention at how to handle it - or maybe watch some videos online before applying, if you don't have experience. Applied in excess is also not good :) Then, it's the peace of mind. This is carbon-based and non-conductive, so you don't have to sweat if a tiny bit escapes onto the motherboard. Unlike liquid metal or silver-based pastes, there is zero risk of short-circuiting your expensive hardware. Remember, read carefully before trusting people on internet. Longevity. Well, ARCTIC claims it lasts for 8 years, and they aren't kidding. I’ve opened up builds from five years ago and the paste was still tacky and performing well, rather than turning into a useless dry crust. Results as you go, how I like to call it. On my last GPU repaste, I saw a drop of 12°C under load. It’s the cheapest way to extend the life of your hardware and keep your fans from screaming. Pros: Excellent thermal conductivity. No "burn-in" time required (reaches peak performance immediately). 4g is plenty (some people say for at least 5–10 applications, my experience says that depends on the builds :) ) Very affordable. Final thoughts. Don't overthink it. Unless you are doing extreme sub-zero overclocking, this is all the thermal paste you will ever need. It’s reliable, safe, and performs brilliantly across PC and console hardware. Highly recommended!
