ARCTIC MX-4 (20 g) - Premium Performance Thermal Paste for All Processors

Here’s a practical, real-world review of the 20-gram tube of Arctic MX-4. It’s written with a natural, no-nonsense tone—like a seasoned builder sharing their experience on a forum or tech blog. Arctic MX-4 (20g) Review: The Old Reliable That Never Fails If you’ve spent any time building PCs or repasting old hardware, you already know about Arctic MX-4. It’s been a staple in the community for years, and honestly, there is a very good reason why people keep coming back to it. I recently grabbed the big 20g tube for a batch of system overhauls, and it reminded me why this stuff is so popular. Application & Consistency The absolute best thing about MX-4 is how easy it is to work with. It has the perfect consistency—not too thick, not too watery. It spreads smoothly under the pressure of the cooler, so whether you’re a fan of the pea-dot method, the "X," or spreading it manually with a spatula, it’s incredibly forgiving. It’s also completely non-conductive and non-capacitive, meaning if you accidentally mess up and spill a little on the motherboard components, you won’t short-circuit your system. It’s totally idiot-proof. Thermal Performance Is it the absolute highest-performing paste on the market today? No. Newer, pricier options might beat it by 1 to 2 degrees Celsius. But for 95% of builds—from mid-range gaming rigs to older console repastes—MX-4 is excellent. It dropped the load temps on my hot-running CPU by about 7°C compared to the dried-out stock paste, and it keeps things perfectly stable. Plus, it has zero cure time, so you get optimal performance the second you boot up the PC. Longevity Arctic claims this stuff lasts up to 8 years once applied. While I usually open up my main rig before that anyway, I’ve pulled apart older office PCs that I pasted with MX-4 five years ago, and the paste was still moist and performing great. You truly can just apply it and forget it. Why the 20g Tube? Buying the 20g tube is pure value. If you’re only building one PC, just stick to the small 4g version. But if you run a small repair shop, have a ton of consoles to refurbish, or just maintain multiple rigs for family and friends, the 20g size is a massive money-saver. The syringe seals up tightly, so it won’t dry out in your toolbox while waiting for the next project. The Verdict Arctic MX-4 isn't flashy, but it is the definition of a workhorse. It offers a perfect balance of easy application, solid thermal drops, long lifespan, and unmatched value. If you want a hassle-free paste that gets the job done right every single time, this is it.

Excellent product, easy to apply, cost effective, laptop ran way cooler after application for less wear & performance on the cooling fan. Highly recommend

Huge tube!!

Excelente disipación por un buen precio

Excelente producto

A tiempo y en exelentes condiciones.

There are better options available these days versus when this first came out -- but not a lot. The Arctic Cooling MX-4 is still an incredible choice with a great price compared to the better options. One of its key selling points from the start is also that it lasts a really long time -- and that hasn't changed. A lot of the options today that perform better still don't last as long. Of course AC MX-5 does, but that costs a fair bit more. This can be a really great compromise in price/performance with much better performance than even many in this price range and there is a lot of it, so this tube will cover a lot of devices for a long time. I've lost track of how many devices I've used it on. Since I have so much I feel free to even use it on things like Raspberry Pis and such that normally you wouldn't use such high grade stuff on.

It has good thermal conductivity and spreads easily. Lots of uses per tube. It's been my go-to paste for a while now.

Para mi, la mejor pasta térmica relación calidad-precio. Llevo usándola años en multitud de equipos portátiles y ordenadores de sobremesa e incluso en videoconsolas (Playstation 4), y el resultado siempre es excelente para su coste. El formato de 20 gramos es muy cómodo, aunque quizás para una aplicación esporádica me decantaría por menos cantidad. Es muy fácil de aplicar y se agradece tener la espátula para repartir de manera uniforme la pasta (yo al menos si la uso). Sin duda, es una de mis pastas térmicas de referencia para la mayoría de usos y usuarios. Recomendada al 100% a menos de que seas un hardcore gamer, que en tal caso quizás, necesites otra opción.

Excellente Pâte Thermique!
