Description

ARCTIC, a leading manufacturer of PC coolers and components, initiated and continues to shape the trend towards quiet cooling systems. The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC‘s MX-4 thermal paste is composed of carbon microparticles which fill these cavities. This leads to extremely high thermal conductivity, ensuring that heat is dissipated quickly and efficiently from the CPU or GPU. With its outstanding performance, the MX-4 is not only an excellent choice for overclockers and enthusiasts, but also for other sapplications that require thermal transmission. Thanks to its consistency, MX-4 is easy to apply, even for beginners. The video in the picture gallery demonstrates the application technique to avoid air pockets between processors and coolers. In contrast to pastes based on metal oxides or liquid metal, ARCTIC’s MX-4 is metal-free and not electrically conductive. This eliminates the risk of short circuiting, and eliminates the need to worry about corrosion damage to the radiator floor caused by liquid metal. To ensure that your paste is genuine, there is the ARCTIC Authenticity Check. This allows every product to be reliably verified. A counterfeit offers neither the performance nor the durability of the original ARCTIC pastes.

As good as the product that cost 8x (yall know what brand I'm speaking of) I have used both on my very high powered gaming setup and this Artic MX4 is as good as any I've used. Enough in the tube for 4-5 applications and the best part is the price to performance. This stuff lowers my hot running I9 14900kf that's over clocked to the max running a quality 360mm AIO down 7 to 9°C over most products and matches the temps of the 40 dollar a tube stuff (you know the brand). The viscosity makes application super easy with just 5 dots and let the pressure from the AIO heat sink spread it out and no worries of air pockets. It holds it's viscosity well and doesn't dry out like a lot of pastes do and that's a huge bonus as it lasts a very long time. The thermal conductivity of this stuff is top tier and competes with the best but at a much more realistic price point. I wouldn't trust a 8k dollar machine to a poor product, I have used the best that cost a ridiculous price and checked it head to head VS this product and this product competes perfectly with it, temps are within +-1°c between this and the best product on the market. With my cooling setup and the infamous hot running I9 14900kf I have no problem maintaining sub 70c temps with higher loads on the system and it's really hard to get it to break 80c with this paste, you have to really be pushing the system HARD. with other budget priced pastes it's easy to get 80C without even pushing it all that hard but this stuff transmits the heat so well over to the cooler that it's just hard to get the temps up. Dollar for dollar easily the best thermal paste on the market. With the best product being around 45 a tube and this being 6 for the same amount of weight and having a +-1c difference between the pastes you have to be a kook to buy the expensive stuff as this performs IDENTICALLY TO IT. Do yourself a favor and save 40 bucks and get this. A 1g tube of the other stuff is 13 bucks and a 4g tube about 45 and here you get 4g of a equal performance product for 6-7bucks lol it's a total no brainer! ... show more

    • Noticeable Temperature Drop After Installation

I recently applied the ARCTIC MX-4 thermal paste to my CPU, and the results were impressive. Before replacing the old thermal paste, my CPU temperatures would regularly reach around 65°C during normal workloads. After applying the MX-4, temperatures now stay below 52°C under the same conditions. The paste was easy to apply, and the included spatula made the process simple and clean. I also appreciate that it's non-conductive, which gives extra peace of mind during installation. Overall, this thermal paste delivered a noticeable improvement in cooling performance and helped lower my CPU temperatures by more than 10°C. If you're looking for a reliable, high-quality thermal paste for your CPU or GPU, I would definitely recommend the ARCTIC MX-4. ... show more

    • Great product
Size: MX-4
First time changing my thermal paste. I was told a few tricks but I ended up using the spatula provided. I set an X on the top and then I spread it to every corner and aligned inward. Made sure the whole thing was covered before re-installing the radiator. Thickness is not too thick not too thin. Just right. Def value for money. Easy to apply. Running games on max settings and I’ve seen it hit no higher then 72. So think we doing good ... show more

    • This is the same great quality as the older version.
Size: MX-4
Newer version of what I got before. Had to do some computer cleaning so I got this to replace the 2018 version I bought before. This applied well, had the spatula to spread the paste and my CPU is like new again after I did the cleaning. My computer was fan revving after 6 years so I needed more paste and this worked just like the older version. I don't use any other brand because the liquid silver causes shorts and other brands are unpredictable. This is the first brand I used and the same brand because I have had good quality with it. ... show more

    • Great Paste. Not thick and great temps.
Size: MX-4
I have to say its good stuff, Put is a assassin cooler, a cheap one for my i5 12400f and the paste was a good viscosity, brought my temps with the mix of the air cooler down to room temp under idle and 40C under load. The assassin cooler for this cpu works wonders literally wont even touch 50C with the two combined So 100% recommend this paste. ... show more

    • A most under-appreciated item.
Size: MX-4
I am about a week on the other side of a recent system build. Meaning that the new system has been in service for about a week. Why did I label this an under-appreciated item? Because without it the CPU probably wouldn't have lasted a minute. Ok, the truth is that if one is building on a motherboard built this century, then the board itself is probably smart enough to shut things down before the CPU cooks. But if one has built a system in the past year, then one knows just how difficult it is to get the core components at present. So, yeah, cooking the CPU would have a more profound and less recoverable connotation. Enter, thermal paste. More specifically, enter one of the most recent formulations of thermal paste. I chose this one because it has significantly higher thermal transmission gradient than the best formulations available just a few years ago, and came in at half the price of its next competitor (at the time of purchase). In reality, they are all priced about the same, but many come with half the volume of stuff inside the tube. And suppose one makes a mistake the first time had needs a do-over (that didn't happen to me, but I prepared for it none the less). So, at about $9 for 4 ml; if this were gasoline it would cost over $170K to fill a 20 gal tank! The other guys were selling 2 ml for the same price so thankfully my car doesn't run on this stuff. But not using it can spend about $200 to $20,000 (Intel Xeon and AMD Epyc CPU builds can start touching this magnitude of cash) in less than a minute. So far, I have stressed my system during video rendering and compositing on a few occasions - it's ok, that's what it was built to do. The CPU is factory rated at 90 degrees C - that's almost hot enough to boil water, but that is the factory established LIMIT. Using this paste along with a liquid-cooled thermal management scheme, my CPU has never gone above 61C during any operation to date including the most stressful. The thermal paste is the transmitter between the CPU and the heatsink. So no cooling strategy will be any more efficient than the paste will allow. Another reason for purchasing a tube with extra paste; some builds use more than one CPU, and sometimes there's an options to provide additional cooling to the GPU. M.2 memory tends to run pretty warm and use heatsinks as well. The point being, anytime there's a heatsink, using thermal paste at the junction will enhance the heatsink's ability to cool the component - the better the paste, the more efficient the cooling. And cooler components run faster and smoother. Solid State memory slows down significantly at higher temperatures, it's called throttling for anyone looking at their first build. So I probably used less than 1 ml to install the CPU - it's more art than exact science, but having more left over is helpful if one has numerous heatsinks to treat during the build. This paste emerged from the tube in a predictable manner - which is good considering the cost per ounce. It came with a mini-spatula for spreading. It sort of resembles a pizza peel if one were providing their pet hamster with its own pizza oven, but I digress. Spreading the paste prior to installing the CPU cooler was very easy and controllable. I was able to achieve edge to edge over the CPU without any dripping to the motherboard - nice, neat, mess-free application. There's also a rating for noise level....ok....um...this paste is pretty quiet. (Amazon asks reviewers to rate a few areas that are not necessarily presented in the public review space other than as an aggregate score). My CPU was at 24C (room temperature) when I powered up this afternoon. It is now at 37C and hasn't gone above 43C during this session. That was probably during Windows boot up. It runs typically between 34C and 38C during low demand. I have read some reviews in which folks describe their systems as running nominally ay 70C! (Methinks these are gaming rigs under full load). So, I guess based on all of this, this paste is pretty effective. But it can only be as effective as the rest of the cooling system it supports. At least I can confidently say that it is not likely to be a weak link - and it has a rating for efficacy over 8 years! I would purchase it again - but I wouldn't fill the gas tank with it. ... show more

Quality thermal paste. I used this four years ago on my Intel i7 11th generation CPU. Along with my AIO it kept it cool even on heavy loads. Sadly she started to overheat from 80- 100°C. It has been a long time but it needed new paster so I had to get this again and now my CPU is cool as a cumbler run at temps of 29-32°C on idle and around 40-50 on heavy loads. It not too thick to apply. The tube is a perfect size to apply the paste. ... show more
