Features
- The Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer
- Made With 99.9% Pure Silver
- Controlled Triple-Phase Viscosity
- High-Density Polysynthetic Silver Thermal Compound
Description
Thermal compound is necessary to create a reliable transfer of heat from your computer's processor to its heatsink to keep your CPU from overheating. Arctic Silver 5 thermal compound does this with three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer. It's optimized for use between modern high-power CPUs and high- performance heatsinks or water-cooling solutions. This 12-gram tube contains enough compound to cover at least 50 small CPU cores, or 20 large CPU cores, or 7 to 15 heat plates.

Arctic Silver 5 is a solid choice for anyone who wants reliable, long-lasting thermal paste with high thermal conductivity. It's particularly favored by those who are looking for a more traditional paste for high-performance systems, but be prepared for a bit of a learning curve during application and some wait time as it cures. If you're building a system for the long haul and can handle the slightly tricky application, it’s a great pick. For newcomers, there are more user-friendly options out there, but if you know what you're doing and want a proven performer, Arctic Silver 5 delivers. Pros -Great thermal conductivity Cons: -Thicker consistency can make application harder -Needs curing time to reach full performance -Can be a bit messy to work with, especially for beginners -Slightly more expensive compared to some budget options

There my be better performing thermal compounds nowadays , but none are as consistent, or as inexpensive as Arctic Silver 5. Over the last decade I've tried many other compounds, and except for expensive Diamond based TIm's, none have been all around as good. I've used AS-5 in commercial cryogenic applications, on electronic components ( Mosfets, bridge rectifiers, etc), and on every PC that I've built. The things I like about it are,.. It cures / sets up fast, (after a few dozen hours usage, temps will drop and level off.) Is easy to remove when servicing. Provides excellent thermal conductivity. And, is not too expensive, :) If you need a really great thermal compound for a good price, no other brand even comes close. Side note ! If you need some compound for more sensitive applications like video cards GPU's, memory, delicate electronic components etc , use Arctic Silver Ceramique.

I don't care what people claim about other pastes, this paste is the best PASTE you can buy. Obviously you could buy liquid metal, but then you aren't talking about paste anymore.... In terms of paste, this is the best you can buy. I have tried so many brands, and ran them all through their paces. This paste consistently outperforms all others. There is another paste brand, that has to do with bears (you either know or you don't but im not gonna say the name outright) and that brand is trash.... Firstly I bought that bear brand from multiple sources. EVERY SINGLE SET would dry out when applying it. Paste should not dry out like that.... now I read online about a bad batch, but lets be honest here, 5 different sellers, 5 different order dates, and all of them would dry out when applying.... to me that says the paste is crap. Apparently the person who invented and sells said paste, doesn't spread the paste? They just do a dot or line. which I guess would stop it from drying out? but still. The best way to apply paste is to spread it. The metal "lid" on top of a cpu is called the heat spreader or IHS. The whole point of that chunk of metal, is to absorb heat from the cpu. If you know about metal, heat expands in metal. So in practice, you want to cover the entire surface area for maximum performance. You got some youtubers who claim to orient your cooler a specific way to help reduce cooling. Bullshit. Maybe if you were doing direct die cooling sure. But for mountain typical coolers, this is not needed. They claim there is a 1-2c difference. They are just full of poop (can't curse on reviews). Anyway, the bear brand dries out, and then doesn't get the same temp results. ALSO NOTE, you HAVE to do the break in period. AS5 used to be sold in plastic packages like everything else back then. That package would specifically state you should break in the paste, 200-500 hour break in. NO REVIEWER will EVER do this break in period. They simply apply paste, test, and record. Which 100% is WRONG. That's like building a house without following instructions, and when it collapses you blame the wood.... no, its USER ERROR. The paste after its break in period will consistently out perform every other PASTE on the market. Its just fact. My 3950x with 4.4ghz overclock (manual OC none of that crap boost nonsense) will idle 32c, gaming 50c, and stress 72c.... I am consistently told that I am a liar by wanna be tech nerds. This cpu is cooled by a 360mm AIO from CM. Those temps are real. I even screen shot my temp reading, and immediately posted it online. And was accused of photoshopping the image.... I didn't even have time to photoshop.... but whatever. People gonna follow mass opinion instead of following actual facts. Best paste. Period.

I use this on all of my computer builds...not the paste that comes with the motherboards.

Been using Arctic Silver Thermal Compound for over a dozen years and have found them to be a very good at keeping my computers cool without noticeable degradation. Application was easy regardless of what method I use. Would recommend them as they are one of the best. Cannot say much more at this time. Will watch temps to ensure no degradation occurs over long periods of time.

Thermals are important. When I first built my PC Two years ago i used the thermal paste provided with the cooler. Just refurbished my setup with a newer cooler and decided to go with arctic silver and I am amazed at how well it disperses the heat. Running AMD products things get hot. Went from 60C to 35C at idle. Hardly break over 65C while under load now.

This is simply a must for system builders who are devoted to the best results! I might also add that I've been building high-performance PCs for many years and have found that this really does produce the best heat transfer temps for CPUs, APUs & GPUs... Best way to apply is a small amount on either heatsink or processor (whichever is smallest), then in a circular fashion, using a very clean finger, spread compound evenly over entire surface, taking care to NOT use too much, just enough to spread under pressure so entire contact surface is covered... I know a lot of guys think it best to put a dot and trust the pressure of heatsink will spread it. While this is true some of the time, it is NOT always true and you want to be sure, especially if you are building your own rig... obviously, clean up finger well afterward before consuming your favorite pizza (or whatever...)
