Una pasta térmica muy buena y confiable
El producto llegó en optimas condiciones, por ese aspecto todo muy bien. Con respecto al producto, es muy buena pasta térmica, cumple excelente su función: dura bastante tiempo, disipa el calor de manera eficiente, no es costosa y te ayuda a mantener en buenas condiciones, no solo tu procesador del PC, sino que también es recomendada para consolas, tarjetas gráficas, laptops, etc.Como dato adicional, me agrada que tenga la espátula para que se pueda esparcir la pasta térmica en el procesador, algo simple, pero muy útil.Súper recomendado.

Worked On A Gigabyte Gaming Laptop
Worked On A Gigabyte Gaming Laptop. Laptop was 4 years old and it was thermal throttling on websites. Used a Youtube video to disassemble the laptop and re apply the paste. It works. The CPU temps are in acceptable values again. I still have a majority of the paste left. Good value for the money compared to other pastes for sale.

It works like thermal paste should. Spreads well.
It conducts heat. It spread easily using the little included spatula. I didn’t need much of the stuff, as I was merely reapplying the thermal paste after a keyboard replacement in a system that required removing the CPU heat pipe and fan and motherboard to get to the keyboard. The system is running fine after surgery. I’d buy this paste again.If anything, they could sell me half this amount of paste at 2/3 the price, and I’d have been even happier.

Dropped my temps and was super easy to apply
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.

Thermal Paste Review
I haven’t used it but it does seem to meet the expectations that’s been advertised. I can’t give it a 5 stars as I’ve not tested it myself but I’ve heard and seen some videos of people using this thermal paste and it looks astonishing! So good I even bought two tubes of it just in case and they’re very compact tubes! And they have a nice shelf life expectancy

Effective!
Lowered CPU heavy-load temps from 90-100 down to 80-90 celsius, normal-moderate load temps from 70-80 down to 60-70 celsius and light load/idle temp from 60-70 celsius down to 55-65 celsius. Not much difference with GPU temps pre and post-application.Easy to apply overall and once can use the spatula or just do the good ‘ol pea, line, 5 dots, etc. application type.

A most under-appreciated item.
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.

La verdad no sé mucho de pastas térmicas, solo estaba buscando una que tuviera buenos comentarios para poder darle mantenimiento a mi PC y a mi laptop. La verdad es que no tengo análisis de temperaturas antes y después del cambio (para eso seguro en youtube lo pueden ver), pero sí les puedo decir que es fácil de aplicar, tiene muy buena consistencia, rinde mucho en verdad, y no he tenido ningún problema de temperatura en las computadoras en las que la puse. La recomiendo ampliamente.

Lo que hace muy bien• Es una masa térmica de muy buena relación calidad/precio, que muchos usuarios consideran “clásica” y fiable para CPUs/GPUs.• Buena especificación técnica: conductividad térmica indicada de 8,5 W/(m·K).• No conduce la electricidad, lo cual la hace segura para uso en componentes electrónicos — menos riesgo si se aplica de más.• Garantiza una durabilidad relativamente alta: algunos datos hablan de hasta 8 años de eficacia. • Aplicación práctica: varios reviews señalan que se extiende bien (aunque no perfectamente).• Es ideal como opción general para la mayoría de montajes de PC, tanto para reemplazo como para nuevas instalaciones.⸻⚠️ Algunos “peros” o cosas a tener en cuenta• Aunque el rendimiento es muy bueno, no es el tope de gama que va a marcar grandes diferencias frente a otras pastas premium.• En cuanto a facilidad de aplicación, algunos usuarios mencionan que “tiende a hilacharse” o que la consistencia no es la más fácil para principiantes.• Dado que viene un tubo de 4 g (en este modelo), para muchos usos podrías necesitar más cantidad (aunque para CPU estándar es bastante).• Si estás en un sistema extremo (overclocking muy agresivo, refrigeración líquida de alta gama, GPU de muy alta potencia) quizá haya mejores pastas con unos grados de margen extra.Mi conclusiónPara la mayoría de usuarios, la ARCTIC MX-4 es una opción excelente: fiable, segura, buena prestación, y con una marca de renombre. Si estás montando un PC, reemplazando la pasta térmica o instalando nuevo disipador y quieres algo seguro sin gastar de más, es una elección muy buena.
