MX-4 (incl. Spatula)

I picked up this Arctic MX‑4 thermal paste because I ran out of paste on my current CPU and wanted something high quality to get my temperatures back down and make sure my cooler was properly seated. I do a lot of PC building for gaming, content creation, and occasional 3D work, so good thermal management is important to me. Even though it’s sitting in my PC parts bag right now waiting for my next re-paste, Arctic MX‑4 has a strong reputation in the enthusiast community as one of the go‑to thermal compounds for everyday builds. It’s composed of carbon microparticles designed to fill microscopic gaps between the CPU and cooler to improve heat transfer more efficiently than stock paste or cheap alternatives. In my system before I retired it, my CPU temps under load were around 55–60 °C, with idle temps around 38–42 °C—and that was with strong airflow around the cooler and stock paste that had seen better days. Based on typical results people get with MX‑4, switching to this paste often results in a noticeable drop in temps, around 3–5 °C, versus older or stock thermal compounds, which matches what many builders report when they upgrade. One of the things I like about MX‑4 is that it’s non‑electrically conductive, so there’s no risk of shorting anything while applying it. It’s also known for long‑term stability, Arctic advertises years of performance without needing to reapply, which gives me confidence that once I put it on, it’ll stay effective through several builds or CPU cooler swaps. Application was easy with the included spatula, and I appreciate that it’s a trusted, tried‑and‑true paste that many builders still use instead of stock stuff. If you’re upgrading your cooler or just need to refresh your TIM, this is a solid, affordable pick that’ll help keep temps in check without being overkill.

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!

This thermal paste works отлично. It’s very easy to apply, spreads smoothly, and significantly improves cooling performance. I noticed better temperatures almost immediately. Great quality, long-lasting, and totally worth it. I would definitely buy it again.

Though somewhat outdated, Arctic MX-4 is still a great performer and easier to apply than liquid metal, while consistently performing well. The product is neither thick nor thin and applies easily, as mentioned above. One tube has been used in over three builds, and up to this point, cooling performance is still good, leading me to confirm that this product is durable and does not dry out quickly. I would recommend this thermal paste.

I used the ARCTIC MX-4 while building my PC, and it performed really well. The paste spreads smoothly, especially with the included spatula, making application straightforward. My CPU temps dropped noticeably, and it feels reliable for long-term use. It’s non-conductive too, so I didn’t have to worry about safety during installation. The only minor downside is that it can be a little pricey for the small tube size, but overall, it delivers excellent thermal performance and peace of mind.

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.

This is a great thermal paste... My CPU has been the coolest it has ever been! Pay the 2 dollars more, seriously, that good.

Good size gives you a spatula amazing stickiness and keeps the cpu cool and works amazingly with great compatibility with the cpu

Très bon produit facile à appliquer

Great product for using with computer parts.

After having a disappointing experience with a cheaper thermal paste, switching to Arctic MX-4 made a huge difference. It was much easier to apply, and the cooling performance on my laptop improved noticeably compared to the previous paste. Temperatures became more stable, and the application process was smoother without the excessive thickness I faced before. Overall, MX-4 proved to be far better and totally worth the extra cost—I highly recommend it for anyone who wants reliable and effective thermal performance.
