The best thermal compound I've used
597806
To start off, I've not actually started using this 20g tube. I'm still using the 4g tube that I've bought a couple of years back. Ever since I started assembling desktops as a hobby, I've found it indispensable.

The 20g tube is good value for 19.90. So instead of going for the smaller 4g tube, I decided to just get the 20g tube since I doubt I'd stop assembling desktops any time soon.

The Arctic MX-4 is easy to apply and it's very effective. It brought my CPU's temperature down significantly. When I upgraded to the Intel 2500K processor, I was able to get very good temperatures on air, even after overclocking it to 4.5GHz. This was with the CM Hyper 212 cooler. The MX-4 is also non-electricity conductive, so for beginners, or even advanced users, it can be a good thing when you've accidentally gotten some onto the board. At least you know the board won't short.

Also, I applied it on my GTX460 and managed to bring those temperatures down as well.

All in all, I'm a very happy user of the Arctic MX-4 and will recommend this to anyone looking for an effective, easy to use and value for money thermal compound.

This has  been the  king of all thermal pastes. Unfortunately, there are better options out there, like Primatech PK-3 or Gelid GC Extreme, or even Arctic MX-4. I used this up until 2014 and once I discovered better options were out there I went to those.

Arctic Silver is probably the best heat conducting paste available. Any person who repairs or builds computers should have a tube of this on their work bench. When I am installing a new new heat sink on a computer, I discard the heat conducting paste provided by the heat sink manufacturer and use this stuff. For best results, it is necessary to make sure that the contact surfaces are perfectly clean. A paper towel dipped in rubbing alcohol works well for this purpose. You just need to make sure the components are perfectly dry before applying the Arctic Silver and assembling the components. Also it is important to use the correct amount of paste. Some people tend to cake it on. If for example the heat sink contact area is about the size of a postage stamp, you only need to use the amount of paste equivalent to a large water drop. Properly applied, this tube will last for several computer repairs/builds.

I put it to the test, it passed. I ran the same CPU intensive operation comparing stock vs silver vs gold. Even before the 200 hour break-in period, under 80% load on an i7 4790k it outperformed Intel's stock thermal compound by 1-2*c. It outperformed the "gold" thermal compound by 4-5*c. It is nice and thick consistency, making application easy.

First off, I LOVE THIS STUFF. It cools way better than Arctic Silver. I've already used it in a rebuild of an&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/EVGA-GeForce-GTX-560-Ti-DS-Superclocked-1024-MB-GDDR5-PCI-Express-2-0-2DVI-Mini-HDMI-SLI-Ready-Graphics-Card-01G-P3-1567-KR/dp/B004XUCCRM/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">EVGA GeForce GTX 560 Ti DS Superclocked 1024 MB GDDR5 PCI Express 2.0 2DVI/Mini-HDMI SLI Ready Graphics Card, 01G-P3-1567-KR</a>&nbsp;and the upgrade of an old PC from Pentium III 866 to Pentium III 933 (super fast and awesome). Highly recommend.

This keeps my CPU super cool. I paired this with Arctic Silver 5 Thermal Compound 3.5 Grams as well.

I purchased this thermal paste since my laptop was having heating issues, after using this amazing heat paste temperature has come down now my machine is very stable as new. I applied it on CPU as well as GPU and works perfect now.

This compound is definitely ahead of the game as far as cooling goes; on average I saw 4-7C differences going from AS5 to this. My only complaint is that the benefits deteriorate over time. You will notice after 8 months or so(in one case I noticed after 4 months) that your temperatures start to increase. This is because the TIM dries out over time and will need to be reapplied periodically. I would imagine that this issue is less pronounced in systems that are not using high end overclocks, but let's be honest here: we would not be on this page if we were not trying to overclock our systems.

Overall I would say this is a commendable product. It is easy to apply and clean and does not leave residue on the surface it is applied to. If you find you are constantly adjusting or changing parts in your system and want a TIM that provides great performance for its price, then this TIM is for you. If you want something that is more "set it and forget it," then you should consider other options.

Excellent product.

My build is a AMD Phenom IIx4 965 Black Edition CPU with a Cooler Master TX3 heatsink. The stock thermal paste was applied almost 4 years ago. My CPU temp while sitting on win7 desktop in idle was about 52 degrees Celsius with 50% fan speed. I removed the old paste using isophyl alcohol (basically concentrated rubbing alcohol: 91%) which can be purchased from any common store and found in First Aid supplies. After removing the old paste and applying the Arctic Silver 5 as best as humanly possible and blowing out all the dusk in my heatsink, I am now getting 38 degrees Celsius on the same desktop at 50% fan speed. Pretty awesome people.

The consistency of the old paste was clearly on the edge of being considered caked and practically baked bread crumb on my CPU. I definitely think thermal paste should be reapplied every couple of years if you have any hope of continuing to overclock or extending the life of your CPU.

First off I bought this with my Coolermaster Hyper 212 Plus CPU Cooler expected to get just another thermal compound. There was more compound in the tube than most that I've used before, I had to enough to cover my CPU and GPU easily. Since it was an upgrade by getting the cooler I wasn't so sure of the effiency of the compound. The solution applied to the GPU was the noticable one, I was worried that I would have to buy a new Video Card due to overheating. After I applied it, I turned it on and instantly I noticed a 9-11C drop. I thought this was weird because it usually runs hot until the compound molds, this is just good stuff. Don't go wrong, stick with these guys and buy the lastest and greatest in thermal compounds!

(just remember to clean your chips good before applying.)

This thermal paste is an excellent option for your hi heat needs. I have noticed a 5 deg Celsius  drop over any other pastes I have used. I highly recommend it

I was a computer technician for 4 years and I have worked on many computers. This thermal paste seemed to work the best out of any other thermal paste that I have used! I've even used this thermal paste on my processor for my personal desktop computer. It has been on there for 2 years now and it is still holding up and in great condition.

Excellent without doubts the best thermal paste, I use it for my processor and for a video card that had no pasta, works perfectly with low temperatures.

About once a year, I replace the thermal paste on all my electronics (laptops, routers, etc), and I always use Arctic Silver 5.  This stuff is almost like magic.  Back when I redid the paste on my wife's 2008 MacBook Pro (remember the Nvidia controversy/recall, anyone?), the screen tearing during video playback literally disappeared.  Of course, the laptop ran about 10-15 C cooler than it had been running, but the visual improvement in operation was just remarkable.

I now make sure to keep my thermal paste nice and clean on all my electronics, and they last much longer than most people would assume they would last.  Great stuff!

Great Thermal paste! Over the years i've been using many thermal paste like Arctic silver 5, Arctic matrix, Ceramique and some Antec like Antec 5. In my opinion this one Noctua its better than all of them. Im using it with an CoolerMaster Hyper 212+ and it works awesome!

Thermal compound works great on electronic assemblies. Perfect heat transfer.

This stuff just absolutely does not work. I thought all thermal compound should be the same but something about this stuff just makes it never stick. You apply it to your CPU and it just seems to disappear. I don't know if it's a matter of the stuff being too runny when it gets exposed to heat, or what, but it doesn't work, it doesn't stay on the CPU and it doesn't keep it cool for more than a couple of days before you have to reapply. Not worth it at all. It claims it will never 'migrate' but it seems to 'migrate' a hell of a lot. Once a week my computer overheats, I check the heatsink, and the damn stuff is all over, but not where it should be.
